Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
NOTES:
2. Zener Voltage (V
Z
).
The zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (T
L
) at 30°C ±1°C and 3/8 lead
length.
3. 2 Square wave Reverse Surge at 8.3 ms soak time.
