The STMicroelectronics SMAJ40CA-TR is an SMAJ Series bidirectional transient voltage suppressor (TVS) diode in an SMA (DO-214AC) surface-mount package. It has a 40V reverse standoff voltage, a 44.4V minimum breakdown voltage, and a 64.5V clamping voltage. The device is rated for 400W peak pulse power and 6.2A peak pulse current.

The SMAJ40CA-TR is used to protect sensitive electronics from voltage transients, ESD, and surge events on lines operating up to 40V. Its bidirectional design suits signal and data lines or AC-coupled circuits where transients can occur in either polarity. It is used in industrial controls, telecommunications, automotive, and consumer equipment by designers adding transient protection.

Fusion’s in-house quality hubs and Prosemi testing facility are fully certified to meet critical industry standards for electronic component inspection and testing.
