The P4SMA20A is a 400W peak pulse power unidirectional TVS diode from Littelfuse. It is designed for general purpose protection of sensitive electronic equipment from voltage transients. The device offers a reverse standoff voltage of 17.1V, a minimum breakdown voltage of 19V, and a clamping voltage of 27.7V at 14.8A peak pulse current.
With a fast response time of less than 1.0ps, the P4SMA20A is suitable for protecting I/O interfaces, VCC bus, and other circuits in telecom, computer, industrial, and consumer applications. The device is packaged in a DO-214AC (SMA) surface mount footprint, enabling compact PCB layouts.
The P4SMA20A operates over a junction temperature range of -65°C to 150°C and has a typical thermal resistance junction-to-ambient of 120°C/W. The package is lead-free plated and halogen-free, with MSL level 1 per J-STD-020.
