SMA6J12A-TR Description

Short technical summary and product information.

The STMicroelectronics SMA6J12A-TR is a Zener-type unidirectional transient voltage suppression (TVS) diode designed to protect sensitive electronics from voltage transients induced by lightning, ESD, and other surge events. It features a reverse standoff voltage of 12V and a clamping voltage of 23.5V at the peak pulse current of 157A (8/20µs waveform). With a peak pulse power dissipation of 600W, it provides robust protection for general-purpose applications in power supply lines, data lines, and I/O interfaces.

 

This TVS diode is housed in a compact, surface-mount DO-214AC (SMA) package, making it suitable for space-constrained designs. It supports a wide operating temperature range from -55°C to 175°C, ensuring reliable performance in harsh environments. The unidirectional polarity allows it to clamp positive transients while offering low leakage current in the reverse direction.

 

Typical applications include protection of DC power buses, communication interfaces, and microcontroller inputs in consumer, industrial, and automotive electronics. The device is RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited) for moisture sensitivity, facilitating easy handling during assembly.
