Notes:
1. Non-repetitive current pulse, per Fig.3 and derated above
TA=25˚C per Fig.2
2. Mounted on Copper Pad area of 1.6x1.6"(40x40mm)
per Fig.5.
3. 8.3 ms single half sine-wave, or equivalent square wave, Duty
cycle= 4 pulses per minutes maximum.
The SA Series is designed specifically to protect sensitive
electronics equipment from voltage transients induced by
lightning and other transient voltage events. These devices are
ideal for the protection of I/O interfaces, Vcc bus and other
vulnerable circuits used in computer and consumer electronic
applications.
