SMLVT3V3
LOW VOLTAGE TRANSIL^TM
FEATURES
s UNIDIRECTIONAL TRANSIL DIODE
s PEAK PULSE POWER : 600 W (10/1000µs)
s REVERSE STAND-OFF VOLTAGE = 3.3 V
s LOW CLAMPING FACTOR
s FAST RESPONSE TIME
s UL RECOGNIZED
DESCRIPTION
The SMLVT3V3 is a Transil diode designed
specifically for protecting 3.3V supplied sensitive
equipment against transient overvoltages.
Transil diodes provide high overvoltage protection
by clamping action. Their instantaneous response
to transient overvoltages makes then particularly
suited to protect voltage sensitive devices surb as
MOS technology and low voltage supply IC’s.
