Notes:
1. Non-repetitive current pulse , per Fig. 3 and derated above T_A = 25^OC per Fig. 2.
2. Measured on 8.3ms single half sine wave or equivalent square wave, duty cycle=4 per
minute maximum.
3. V_F<3.5V for devices of V_BR <_ 200V and V_F<5.0V for devices of V_BR >_ 201V.
Description
The SA Series is designed specifically to protect sensitive
electronic equipment from voltage transients induced by
lightning and other transient voltage events.
