P4SMAJ10 is an SMD transient voltage suppressor diode designed for overvoltage and ESD protection in commercial and industrial applications. It features a stand-off voltage (VWM) of 10 V with a breakdown voltage (VBR) of 11.1 V, and delivers peak pulse power dissipation of 400 W at a 10/1000 µs waveform with steady-state power dissipation of 1 W at 75°C. The device exhibits very fast response time and is available in unidirectional (A) and bidirectional (CA) versions in the SMA package (DO-214AC equivalent). With a maximum forward voltage of 3.5 V at 25 A and thermal resistance of 70 K/W junction-to-ambient, the P4SMAJ10 is ideal for protecting sensitive circuits against transient overvoltage events, free-wheeling applications, and ESD discharge scenarios in consumer electronics and industrial equipment.
