Applications
Notes:
1. Non-repetitive current pulse , per Fig. 4 and derated aboveTJ (initial) =25OC per Fig. 3.
TVS componants are ideal for the protection of I/O
interfaces, VCC bus and other vulnerable circuits used in
telecom, computer, industrial and consumer
electronic applications.
2. Measured on 8.3ms single half sine wave or equivalent square wave, duty cycle=4 per
minute maximum.
