Silicon Avalanche Diodes

500 Watt Axial Leaded Transient Voltage Suppressors

RoHS

SA Series

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

MAXIMUM RATINGS AND CHARACTERISTICS @25˚C

AMBIENT TEMPERATURE (unless otherw ise noted)

• Fast response time: typically less than 1.0ps from 0 Volts to

BV for unidirectional and 5.0ns for bidirectional types
