SM15T39A Description

Short technical summary and product information.

The SM15T39A is a unidirectional Zener TVS diode designed for general-purpose transient voltage suppression. It features a reverse standoff voltage of 33.3V and a clamping voltage of 69.7V at a peak pulse current of 143A (8/20µs waveform). The device can handle 1500W of peak pulse power, making it suitable for protecting sensitive electronics from voltage transients.

 

This TVS diode is housed in a surface-mount DO-214AB (SMC) package and supports an operating junction temperature range of -55°C to 150°C. It is RoHS3 compliant and has an MSL of 1 (unlimited). The unidirectional configuration provides protection for a single channel, and the device does not include power line protection features.

 

Typical applications include general-purpose circuit protection in consumer, industrial, and automotive electronics where reliable clamping of transient overvoltages is required. The SMC package enables automated assembly and is compatible with standard reflow soldering processes.
