طقم صمام ثنائي زينر 1/2 واط 0.5 واط 2.4 فولت-27 فولت 25 قيمة مختلفة (عبوة من 250)

Finally got around to building my reference voltage source and these zeners were spot on, within a few mV of their marked values. The 2.4V to 33V range covers everything I need for simple protection circuits.

The color bands on these are actually legible without a magnifying glass, which is a huge win for my tired eyes. I sorted all 25 values into my drawer and every one of the 10 pieces per value tested right at the specified voltage. For the price, having 2.4V all the way up to 33V covered is perfect f

Finally got around to testing a few values from this kit and the voltages were dead on for my little bench supply projects. Having 10 of each value from 2.4V up to 33V is a huge time saver compared to hunting down individual diodes.
