SMA6J18A-TR Description

Short technical summary and product information.

The SMA6J18A-TR is a unidirectional transient voltage suppression (TVS) diode from STMicroelectronics, designed for general-purpose circuit protection. It features a reverse standoff voltage of 18V and a maximum clamping voltage of 33.2V at a peak pulse current of 102A (8/20µs waveform). With a peak pulse power rating of 600W, this device provides robust protection against voltage transients.

 

This TVS diode is housed in a surface-mount DO-214AC (SMA) package, making it suitable for automated assembly processes. It operates over a wide temperature range from -55°C to 175°C, ensuring reliability in demanding environments. The unidirectional configuration is ideal for protecting DC lines and low-voltage circuits.

 

Typical applications include general-purpose transient protection in consumer electronics, industrial controls, and communication equipment. The SMA6J18A-TR is RoHS3 compliant and REACH unaffected, supporting environmentally conscious designs.
