The SMAJ20A-TR is a 400W unidirectional Zener TVS diode from STMicroelectronics, designed for general purpose transient voltage suppression. It offers a standoff voltage of 20V and a clamping voltage of 42.8V at a peak pulse current of 54A (8/20µs waveform). The device is capable of handling 400W peak pulse power, making it suitable for protecting sensitive electronics from voltage spikes.
This TVS diode is housed in a surface mount DO-214AC (SMA) package, which is widely used for compact designs. The operating temperature range is -55°C to 150°C, allowing use in various environments. With a single unidirectional channel, it provides protection for one line.
Typical applications include general purpose circuit protection in consumer, industrial, and automotive electronics (though not specifically rated for power line protection). The device is RoHS3 compliant (unverified) and has an MSL rating of Level 1 (unverified).
