| SM2T3V3A Low voltage TRANSILTM Features Unidirectional Transil Diode High peak pulse power : 200 W (10/1000 s) Stand-off voltage 3.3 V Low clamping factor VCL/VBR Fast response time JEDEC registered package outline K Description The SM2T3V3A is a Transil diode designed specifically for portable equipment and miniaturized electronic devices subject to ESD transient overvoltages. It's low stand-off voltage makes it suitable for low voltage applications very sensitive to EOS and ESD events. Transil diodes provide high overvoltage protection by clamping action.
