The P4SMA56A is a 400W peak pulse power unidirectional Zener TVS diode from Littelfuse, designed for protecting sensitive electronic equipment from voltage transients. It offers a reverse standoff voltage of 47.8V and a clamping voltage of 77V at a peak pulse current of 5.3A (10/1000µs waveform).
This device features a fast response time of less than 1.0ps from 0V to breakdown voltage, making it suitable for high-speed transient protection. It is rated for a peak forward surge current of 60A (8.3ms single half sine wave) and operates over a junction temperature range of -65°C to 150°C.
The P4SMA56A is housed in a surface mount DO-214AC (SMA) package, suitable for compact PCB layouts. It is RoHS3 compliant, halogen-free, and has a moisture sensitivity level (MSL) of 1 (unlimited). The device is ideal for general purpose applications including I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
The reverse standoff voltage (VRWM) is 47.8V.
The clamping voltage (Vc) is 77V.
The peak pulse power (Ppp) is 400W at 10/1000µs waveform.
It is available in a surface mount DO-214AC (SMA) package.
Yes, it is RoHS3 compliant and halogen-free.
