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 4. MAXIMUM ZENER CURRENT RATINGS (I
)
ZM
Values shown are based on the JEDEC rating of 400 mW. Where the actual zener voltage
(V ) is known at the operating point, the maximum zener current may be increased and is
Z
limited by the derating curve.
NOTE 2. ZENER VOLTAGE (V ) MEASUREMENT
Z
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.
