    The stated zener values are “nominal” in that they measure within 5% or less of the stated value but the range of the diodes in the group are sufficient that one can find one to fit the use required.

    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.

    Excellent value

    The kit has an excellent assortment of voltage ratings. The diodes are neatly packaged with clearly marked values. I’ve used 2 thus far, and they both operate at proper specs.

    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.

    Lower voltages shorted or mislabeled

    Needed to replace a 3.6 and figured I would buy a bundle for future repairs. MAKE SURE TO MEASURE THE VOLTAGE BEFORE ADDING TO YOUR CIRCUIT!Ended up finding a 3.6 in the 4.3 pack because all of the diodes registered smaller were below 3.0. Not sure if these are all shorted or mislabeled but double check.

    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 diodes and are prepared for any situation.

    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

    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.

    Nice to have several different diodes. So far it’s working gre

    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 be of decent quality and I don’t expect any issues.

    Nice assortment

    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.

  36. 59

    by Charles Seiler

    A good value.

    I have been needing this set for ages. In the past I would purchase a few Zener Diodes of different voltages, and I’d still never seem to have the correct voltage I needed. This set solves that issue. Everything you need as a set. I haven’t done a careful analysis of the voltage rating of each of these diodes. However, in my projects, I haven’t needed finite precision. This seems to be a good set. I’ll update more when I’ve tested these and can review their working quality.

    Great value.

    As a electronic engineer and technician many of the devices we produce demand accuracy.Each zener diode within this assortment was placed in a curve tracer and every diode tested was within tolerance +/- .05.

    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.

    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!

    Great pack of zener diodes for fair price

    Great variety pack of zener voltages! I do repairs and projects, these are reasonable and seem like quality. I recommend.

    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.

    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.

    Great selection of Zener diodes!

    These were delivered very quickly and are a fantastic selection of various voltages of Zener diodes. I was able to repair an acoustic guitar amplifier and now have a collection of hundreds of spare Zener diodes, at a wonderfully low price.

    So far so good

    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.

    Perfect variety!

    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.

    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).
