Stresses exceeding those listed in the Maximum Ratings table may damage the
device. If any of these limits are exceeded, device functionality should not be
assumed, damage may occur and reliability may be af fected.
1. These ratings are limiting values above which the serviceability of the diode
may be impaired.

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.
