The P4SMA400A is a 400W peak pulse power unidirectional TVS diode from Littelfuse designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 342V and a clamping voltage of 548V at 800mA peak pulse current (10/1000µs waveform). The diode offers an exceptionally fast response time of less than 1 picosecond from 0V to breakdown voltage.
Typical applications include I/O interface protection, VCC bus protection, and overvoltage protection in telecom, computer, industrial, and consumer electronic circuits. The device is rated for operating temperatures from -65°C to 150°C and has a storage temperature range of -65°C to 175°C.
The P4SMA400A is housed in a surface mount DO-214AC (SMA) package. It is halogen-free, lead-free plated, and RoHS compliant. The package meets MSL level 1 per J-STD-020. Thermal resistance is 120°C/W junction-to-ambient and 30°C/W junction-to-lead.
