VF Forward Voltage = 1.5V max @ IF = 100mA for all types
2. TOLERANCE AND VOLTAGE DESIGNATION
The type numbers listed have zener voltage min/max limits as shown.
3. REVERSE ZENER VOLTAGE (VZ)
Reverse zener voltage is measured under pulse conditions such that TJ is no more than 2℃ above TA.
4. ZENER IMPEDANCE (ZZ) DERIVATION
ZZT is 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.
