SMAJ12A-TR Description

Short technical summary and product information.

The SMAJ12A-TR is a 400W unidirectional TVS diode designed for general purpose circuit protection. It offers a reverse standoff voltage of 12V and a maximum clamping voltage of 25.3V, with a peak pulse current rating of 91A (8/20µs). The device is housed in a surface mount SMA (DO-214AC) package, suitable for automated assembly. It operates over a junction temperature range of -55°C to 150°C. This TVS diode is intended for applications requiring transient voltage suppression on low-voltage signal or power lines, though it is not specified for power line protection. The part is RoHS3 compliant (unverified) and has an MSL of 1 (unlimited).
