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.
