Yes, you know what you are getting

Cheap chinese parts that are good for prototyping simple circuits, but not for production or permanent use. They have no datasheets or specs, and likely wouldn't meet them even if they had them. You know what you are getting when you pay this little for a huge set of parts. Don't expect miracles, and buy good parts from a reputable dealer if you are building or repairing something that you care about.

Pros
  • The item appears to be "AS ADVERTISED", thank you.
Cons
  • Not suitable for inexperienced electronic enthusiasts

Revainrating 2 out of 5

3v and 3.3v diodes are defective. so far

at 50mA max through the diode, the voltage drop across the 3.3V diode was 4.05V and 3.95V for two that I tested. One of the 3V diodes had a 3.85V drop. These are essentially useless, and I will have to buy a different set. I will need to double check all of the remaining diodes since in electronics, accuracy matters.

Pros
  • Many more than I needed but it is a good assortment.
Cons
  • Some diodes can malfunction, resulting in a waste of money

Great assortment for the price

Appears to be good quality, I was able to match a defective/burnt component through trial and error. System is working and stable to date.

Pros
  • They work as good as any other. So why pay more?
Cons
  • The voltage selection does not include higher voltages

Nice assortment for my opinion

Great assortment of Zener diodes. Wish there were some documentation but I guess if you’re buying you kinda should know.Used on kids science project. As far as I know these worked, but I don’t really have the knowledge to know for sure. The science project kinda flopped but I don’t know if was the diodes fault.

Pros
  • Used for repairs and project / experimenting.
Cons
  • The plastic storage box is fragile and not high-quality

Revainrating 5 out of 5

Guatanteed a full year! Free replacement.

Have not tried these yet but they appear to be good quality. The fact that they a guaranteed for a full year gives me plenty so if I find any subpar ones I can get them replaced. So far very pleased with the purchase.

Pros
  • Nice to have pack of zeners if you’re prototyping circuits.
Cons
  • The assortment may not have sufficient voltage options for some projects

Revainrating 5 out of 5

So far so good good for me

Review based on product as received, not yet tested. Item is as represented in photos, printing on body is very small, so if you do breadboarding, you'll want to take care to keep them separated or keep a jeweler's loupe handy.

Pros
  • Arrived in a day, good assortment, well marked so no magnifying glass required...
Cons
  • The package is not customizable to specific voltage requirements

Revainrating 5 out of 5

A tiny piece of component!

Very good product for a must reliable component on a any regulator circuit. Good power margin and price. Recommend it! The size of the package can be improved for easy storage.

Pros
  • Exactly as described. Diodes clearly marked. Great price.
Cons
  • The size of the package can be improved for easy storage

Only needed one of these for my specific project, however the price was good so rather than paying a very similar cost for a single diode or a pack of multiple diodes of the same spec, i figured sooner or later I’ll need another one with a different voltage spec so it’s nice to have a decent selection now in my electronics parts toolbox. I’ve only had the diode installed for a day now but it appears to be working as it should.Can’t speak to the long term reliability as of yet, but they seem to…

Pros
  • Exactly as described and what was purchased. Very satisfied customer
Cons
  • The diodes in the kit come in a random mix, making it difficult to find the one you need

Great Zener diode assortment

I am totally impressed by the quality and affordability of this handy Zener Diode kit. The diodes are new with full-length axial leads, grouped by value and clearly marked. I have measured the breakdown voltage on the lower values and they also appear to be accurate. I can recommend this kit for any electronic hobbyist/engineer.

Pros
  • Revain is always accurate and on time, items matched description perfectly.
Cons
  • The packaging needs to be more secure

Zener diode assortment protects MOSFETs

This has been a very good assortment of voltage references and most importantly protection diodes. They are used in I/O designs and MOSFET gate protection. I did have to build a current limited reverse voltage tester but have not found any diodes miss-marked or out of range.

Pros
  • Used several of them , no defective ones thus far.
Cons
  • Some diodes will experience voltage drift over time

Revainrating 5 out of 5

A useful selection of Zener voltages

Bought these for a hobby project where I needed varying voltage regulation/over-voltage protection (lead acid battery constant voltage charging circuit). A nice selection of useful Zener voltages also means I have plenty for other projects (older computer power supplies particularly where 0.5W Zeners don't last well).

Pros
  • They are nice and allot for future projects
Cons
  • The kit may contain diodes with a high drop-out voltage

Revainrating 5 out of 5

Inexpensive and retty accurate for the money

Large selection. Low cost. Low levels accurate to within a few percent which is great for hobby use. Higher levels slightly better overall.

Pros
  • Item as described, great set of parts. Had all the values I needed. Prompt shipping.
Cons
  • Returned - no longer needed.

Revainrating 5 out of 5

Good parts, super value

easier, quicker and cheaper to buy this whole assortment than to get just the few I needed from an electronics store or distributor like Mouser.

Pros
  • Complete set for my project, all popular range, for now and future.
Cons
  • The diodes may not be compatible with all applications

A great assortment to have on hand

I was repairing a Tivoli radio that had a problem in the power supply. It has a Zener diode I was not sure the diode was the problem and I couldn't read the number on it to order one. I didn't want to un solder it to find the number. For a little more money than buying just the exact diode and having it shipped I bought this comprehensive selection on Prime. The Zener diode was not the problem and I didn't use one out of the kit so I can't comment on them. Now I have a good selection of Zener…

Pros
  • Good Quality Nicely packaged fast shipping
Cons
  • The length of the leads on the diodes is short compared to other kits

Revainrating 3 out of 5

They all came intact

Update, i bought these to do a diode mod on my Volkswagen, one already blew out in less then a month so it my rating is going from 5 stars to 3

Pros
  • good buy, all tested good
Cons
  • The diodes' quality may not meet professional standards

Revainrating 5 out of 5

Perfect variety! for my opinion

My 3rd brake light went out on my 97 land cruiser and it was because of one of the resistors. I soldiered a new one in from this pack and everything works like new! Plus, I have 99 pieces for many other applications.

Pros
  • Used one part. It functioned as it should.
Cons
  • The kit lacks newer Zener diodes

Revainrating 5 out of 5

Great diodes with a variety

Perfect! These worked fantastically! Needed some for running multiple switches to one light and didn't want it to backfeed and power the other switches. A very good assortment of voltage ranges. 10 diodes per voltage. I only needed the 12v ones for my cars system. Just note they are only 1w rated so very light applications. Very happy!

Pros
  • Good assortment, well-packaged, works as expected so far.
Cons
  • The kit does not come with instructions on usage
