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
