The P4SMAJ85CA is 400W, 85V, TVS Diode.

A Transient Voltage Suppressor (TVS) diode is a type of semiconductor device that is specifically designed to protect electronic circuits from voltage spikes, also known as transients. These transients can occur due to a variety of reasons such as switching events in the power supply, electrical noise, and electrostatic discharge (ESD).

TVS diodes are typically connected in parallel with the circuit that needs protection, and when a voltage spike occurs, the TVS diode conducts, thereby diverting the surge current away from the protected circuit. Once the voltage spike has subsided, the TVS diode returns to its non-conducting state, allowing normal circuit operation to resume.
