NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION
Tolerance Designation
The type numbers shown have tolerance designations as follows:
1N4370A series:
±5% units, C for ±2%, D for ±1%.
1N746A series:
±5% units, C for ±2%, D for ±1%.
1N957B series:
±5% units, C for ±2%, D for ±1%.
NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT
Nominal zener voltage is measured with the device junction in thermal equilibrium at the lead
temperature of 30
°C ±1°C and 3/8″ lead length.
NOTE 3. ZENER IMPEDANCE (ZZ) DERIVATION
ZZT and ZZK are measured by dividing the ac voltage drop across the device by the ac current
applied. The specified limits are for IZ(ac) = 0.1 IZ(dc) with the ac frequency = 60 Hz.
NOTE 4. MAXIMUM ZENER CURRENT RATINGS (IZM)
Values shown are based on the JEDEC rating of 400 mW. Where the actual zener voltage
(VZ) is known at the operating point, the maximum zener current may be increased and is
limited by the derating curve.
