500 Watt Axial Leaded Transient Voltage Suppressors

MAXIMUM RATINGS AND CHARACTERISTICS @25˚C AMBIENT TEMPERATURE (unless otherwise noted) UNIT Watts Amps Watts Amps 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.
