Nominal
Voltage
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 I ZT
(or I ZK ) superimposed on DC I ZT (or I ZK )
Temperature Coefficient test conditions:
a. I ZT = 7.5mA , T 1 = 25°C, T 2 = 125°C (1N5221A, B through to 1N5242A, B)
