SMAJ40CA-TR Description

Short technical summary and product information.

The SMAJ40CA-TR is a bidirectional Zener TVS diode from STMicroelectronics, designed for general purpose transient voltage suppression. It has a standoff voltage of 40V and a maximum clamping voltage of 84V at a peak pulse current of 27A (8/20µs). The device can dissipate up to 400W of peak pulse power. It operates over a junction temperature range of -55°C to 150°C.

 

The device is housed in a surface mount DO-214AC (SMA) package, making it suitable for automated assembly. It features a single bidirectional channel and does not provide power line protection. The SMAJ40CA-TR is RoHS3 compliant, REACH unaffected, and has an MSL rating of 1 (unlimited).

 

Typical applications include general purpose transient voltage suppression in consumer and industrial electronics, protecting sensitive circuits from electrostatic discharge (ESD) and surge events.
