SM5908
TRANSIL^TM
FEATURES
UNIDIRECTIONAL TRANSIL DIODE
PEAK PULSE POWER : 1500 W (10/1000µs)
REVERSE STAND OFF VOLTAGE : 5 V
LOW CLAMPING FACTOR
FAST RESPONSE TIME
UL RECOGNIZED
DESCRIPTION
The 1N5908 and SM5908 are dedicated to the 5 V
logiccircuit protection(TTL and CMOS technologies).
Their low clamping voltage at high current level
guarantees excellent protection for sensitive
components.
