P4SMAJ43A Description

Short technical summary and product information.

The P4SMAJ43A is a unidirectional transient voltage suppressor (TVS) diode from Diotec Semiconductor. It features a reverse standoff voltage of 43 V and a maximum clamping voltage of 69.4 V, providing robust protection against overvoltage events. With a peak pulse power dissipation of 400 W (10/1000 µs waveform) and a steady state power dissipation of 1 W, it is suitable for general purpose circuit protection applications.

 

This TVS diode is housed in a surface mount SMA (DO-214AC) package, weighing approximately 0.07 g and made with UL 94V-0 case material. It supports solder and assembly conditions of 260°C/10s and carries an MSL rating of 1 (unlimited). The operating temperature range is -50°C to 150°C.

 

The P4SMAJ43A is compliant with RoHS3 (exemption 7a), REACH, and Conflict Minerals requirements, making it suitable for environmentally conscious designs. It is supplied in tape and reel packaging with 7500 units per 13" reel.
