Zener Diodes Kit, 1W Power Diode Assorted Assortment Box Kit Set (3.3V/3.6V/3.9V/4.3V/4.7V/5.1V/5.6V/6.2V/6.8V/7.5V), Range 1N4728~1N4737,Pack of 200, By Ltvystore

Unlike with some of the earlier reviews, these appeared to be well sorted - I pulled a number of them and checked their markings (with a magnifying glass) and they were all in the correct locations. In all, a nice assortment at a good price.

Everything is in order. Other people gave this bad reviews, however I had absolutely no problems whatsoever. Also to reply to the others complaining about having to test components, it is good practices to test components anyway. Anyway I'll buy more again later

super price for a box of 200 low power zeners for your project box

Had to come back to the web-page here and get the voltage values for the Zeners and label the voltage values in the box myself.

Good value

I just tried to find a 4.7V Zener (1N4732) from this product and because of the UNSORTED and MIS-LABELED product, I gave up and just used a 5.1V zener instead. The 1N4732 is part of this product, but with a jeweler's magnifier I searched and searched and searched. They are not completely sorted and they definitely are not sorted to match the labeling. The first thing you must do when you get this product (because the voltage is not marked) is to research the zener diode numbers (1Nxxxx) and remove these from the plastic box. The box is useless because the partitions come out when removing diodes. This just mixes them all back up again. You'll need to spend about an hour or so completely separating these, sorting them, and placing them into a separate container. It takes a long time because you must use a magnifier and rotate each diode to read the values. No big problem if you are prepared to do waste lots of your time. So, just be prepared to go through about 200 diodes with your magnifiers on and separate and sort them and then place them in SEPARATE containers, marked accurately. The diodes are probably just fine themselves but forget trying to use this product as it arrives to you. Just FYI. It would have been so much better if the seller had placed these in separate, clear plastic bags. -- not this cheesy box with partitions that dislodge easily and re-mix any sorting you may have spent time doing. Throw the box aside for another purpose -- it's terrible for 200 zeners.

very good product .

I was indeed warned. But I experienced a triumph of hope over experience, and ordered them anyway.And this box of diodes is like a box of chocolates: you don't know what you're going to get. The diodes came scrambled in an unsuitable container, just like the reviews said. And I've found one so far (out of 20 checked) that is either defective or is a part number that is not on the list. The picture shows that it registers 1 volt. The part number is illegible.You'll want to print the value chart from the sales page, as the label in the box does not include the Zener voltage (or current, or resistance, etc.)While absolutely unsuitable for any commercial purpose, if you're working in a development lab or as a hobbyist, the value for money is still OK. They lost two value stars for the hassle of having to sort them all and find another way to store them. Accuracy gets two stars because they are so mixed up, the box label is only a guess at what's there.And you should be wondering about the quality of the parts. Will they last? No one knows. But that aside, they're likely fine at a lab bench. Not OK at all for anything else.
