2. TOLERANCE AND VOLTAGE DESIGNATION
The type numbers listed have a standard tolerance on the nominal zener voltage of ±5%.
3. ZENER VOLTAGE (VZ) MEASUREMENT
The zener voltage (VZ) is tested under pulse conditions such that TJ is no more than 2℃above TA.
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
)
This data was calculated using nominal voltages. The maximum current handing capability on a worst case basis is limited by the
actual zener voltage at the operation point and the power duration curve.
