P4SMA550CA Description

Short technical summary and product information.

The P4SMA550CA is a bidirectional TVS diode from Littelfuse, part of the P4SMA series. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning and other transient events. With a standoff voltage of 495V and a maximum clamping voltage of 760V, it provides robust protection for high voltage applications.

 

This TVS diode offers a peak pulse power dissipation of 400W for a 10/1000µs waveform, with a peak pulse current rating of 500mA. It features a fast response time of less than 1.0ps from 0V to breakdown voltage, ensuring rapid clamping of transients. The device also includes ESD protection rated at 30kV for both air and contact discharge per IEC 61000-4-2.

 

The P4SMA550CA is housed in a DO-214AC (SMA) surface mount package, suitable for compact PCB layouts. It has an operating temperature range of -65°C to 150°C and is lead-free and halogen-free compliant. The device is ideal for general purpose use in telecom, computer, industrial, and consumer electronic applications.
