P4SMA170CA Description

Short technical summary and product information.

The Littelfuse P4SMA170CA is a bidirectional TVS diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It features a reverse standoff voltage of 145V and a maximum clamping voltage of 234V at a peak pulse current of 1.8A (10/1000µs waveform). The device can handle 400W of peak pulse power dissipation under the same waveform conditions.

 

This TVS diode offers fast response time of less than 1ps from 0V to breakdown voltage, making it suitable for high-speed transient protection. It is rated for ESD protection up to 30kV (air and contact discharge) per IEC 61000-4-2. The bidirectional configuration allows protection of circuits where voltage can swing in both polarities.

 

The P4SMA170CA is housed in a DO-214AC (SMA) surface mount package with matte tin, lead-free termination finish. It is RoHS3 compliant and halogen-free, with an MSL rating of Level 1 (unlimited floor life). The operating junction temperature range is -65°C to 150°C. Typical applications include I/O interfaces, VCC bus protection, and vulnerable circuits in telecom, computer, industrial, and consumer electronics.
