SMAJ28A-TR Description

Short technical summary and product information.

The SMAJ28A-TR is a unidirectional TVS (transient voltage suppression) diode from STMicroelectronics, designed for general purpose overvoltage protection. It features a reverse standoff voltage of 28V, a minimum breakdown voltage of 31.1V, and a maximum clamping voltage of 59V at a peak pulse current of 39A (8/20 µs waveform). The device is rated for 400W peak pulse power in a 10/1000 µs waveform. It is not intended for power line protection. The diode is housed in a surface-mount DO-214AC (SMA) package, with an operating temperature range from -55°C to 150°C (junction). The component is RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited floor life). Note: compliance data is unverified and should be confirmed from official documentation.
