1 / 4 page Silicon Avalanche Diodes 286 www .littelfuse .com 500 Watt Axial Leaded Transient Voltage Suppressors ® MAXIMUM RATINGS AND CHARACTERISTICS @25˚C AMBIENT TEMPERATURE (unless otherwise noted) UNIT Watts Amps Watts Amps °C 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. FEATURES • RoHS Compliant • 5.0 to 180 Volts • Uni-directional and Bi-directional • Glass passivated chip junction • 500W peak pulse power capability on 10/1000µs waveform • Excellent clamping capability • Repetition rate (duty cycle): 0.01% • Low incremental surge resistance • Fast response time: typically less than 1.0ps from 0 Volts to BV for unidirectional and 5.0ns for bidirectional types • Typical IR less than 1µA above 10V • High temperature soldering guaranteed: 265˚C/10 seconds/.375",(9.5mm) lead length, 5lbs.,(2.3kg) tension Agency Approvals: Recognized under the Components Program of Underwriters Laboratories.
