The P4SMA47CA is a 400W peak pulse power transient voltage suppression (TVS) diode from the Littelfuse P4SMA series. It provides bidirectional protection against voltage transients induced by lightning and other events. Key electrical characteristics include a reverse standoff voltage of 40.2V, maximum clamping voltage of 64.8V at 6.3A peak pulse current (10/1000µs waveform), and an operating temperature range of -65°C to 150°C.
The device is designed for surface mount assembly in a DO-214AC (SMA) package. It features very fast response time (typically less than 1ps from 0V to breakdown) and low leakage current. Thermal characteristics include steady state power dissipation of 3.3W and junction-to-lead thermal resistance of 30°C/W typical.
Applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronic equipment. The P4SMA47CA is RoHS3 compliant, halogen-free, and meets MSL level 1 per J-STD-020.
The maximum reverse standoff voltage is 40.2 V.
The maximum clamping voltage is 64.8 V.
The peak pulse current is 6.3 A under 10/1000μs waveform.
The package is DO-214AC (SMA) for surface mount.
