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. REVERSE LEAKAGE CURREN (IR)
Reverse leakage currents are guaranteed and measured at VR shown on the table.
5. MAXIMUM ZENER CURRENT RATINGS (IZM
)
Maximum zener current ratings are based on maximum zener voltage of the individual units and JEDEC 250 mW rating.
6. MAXIMUM VOLTAGE CHANGE (∆VZ)
Voltage change is equal to the difference between VZ at 100uA and at 10uA.
