The P6SMB400CA is a surface mount Transient Voltage Suppressor (TVS) Diode with lead-free matte tin-plated terminal. The transient voltage suppressor (TVS) diode is a protection diode designed to protect electronic circuits against transients and overvoltage threats such as EFT (electrically fast transients) and ESD (electro-static discharge). The TVS diode is silicon avalanche devices typically chosen for their fast response time (low clamping voltage), lower capacitance and low leakage current. The TVS diode is available in bidirectional (bi-polar) diode circuit configuration. The P6SMB series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
