Zener Voltage (VZ) The zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (TL) at 30°C ± 1°C and 3/8” lead length. 2. Maximum Zener Current Ratings (IZM) The maximum current handling capability on a worst case basis is limited by the actual zener voltage at the operation point and the power derating curve. ©2004 Fairchild Semiconductor Corporation 1N4370A - 1N4372A 1N746A - 1N759A, Rev.
