2. TOLERANCE AND TYPE NUMBER DESIGNATION (VZ)
The type numbers listed have a standard tolerance on the nominal zener voltage of ±5%.
3. ZENER VOLTAGE (VZ) MEASUREMENT
Nominal 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.
4. 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 AC frequency = 60Hz.
5. MAXIMUM ZENER CURRENT RATINGS (IZM)
Values shown are based on the JEDEC rating of 400mW where the actual zener voltage (VZ) is known at the operating
point, the zener current may be increased and is limited by the derating curve.
