Semelab encourages customers to verify that datasheets are current before placing orders.
Zener Impedance is measured to ensure a sharp knee characteristic on the breakdown curve. Derived from 50Hz ac voltage from ac current of 10% rms of IZT
(or IZK) superimposed on DC IZT (or IZK)
Temperature Coefficient test conditions:
a. IZT = 7.5mA , T1 = 25°C, T2 = 125°C (1N5221A, B through to 1N5242A, B)
b. I
= 7.5mA , T = 25°C, T = 125°C (1N5243A, B through to 1N5281A, B)
