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 affected. 1. These ratings are limiting values above which the serviceability of any
semiconductor device may be impaired. Non−recurrent square wave Pulse Width = 8.3 ms, TA = 50°C.

VF Forward Voltage = 1.2 V Max. @ IF = 200 mA 2. Zener Voltage (VZ). The 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.
