SMAJ30CA-TR Description

Short technical summary and product information.

The SMAJ30CA-TR is a bidirectional transient voltage suppression (TVS) diode designed to protect sensitive electronics from voltage transients. It features a reverse standoff voltage of 30V and a maximum clamping voltage of 64.3V at the peak pulse current of 36A (8/20µs waveform). With a peak pulse power rating of 400W, it provides robust protection for general-purpose applications. The device is housed in a DO-214AC (SMA) surface-mount package, suitable for automated assembly. It operates over a junction temperature range of -55°C to 150°C. This TVS diode is RoHS3 compliant and has an MSL of Level 1 (unlimited). Note that compliance data is unverified and should be confirmed from official documentation.
