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.
