Product details

1500W transient suppressor for 171V rails

The STMicroelectronics SM15T200A is a Zener-type transient voltage suppressor from the TRANSIL™ series, designed to clamp voltage transients on power rails and signal lines in general-purpose equipment. Its 1500W peak pulse power rating (1.5kW) handles substantial surge energy, while the 171V reverse standoff voltage means it sits across a 170V nominal rail without conducting. The 353V clamping voltage at the peak pulse current of 28A (8/20µs waveform) defines the maximum voltage the protected circuit sees during a surge event.

The 353V clamping maximum at 28A peak pulse current defines the voltage downstream components see during a surge. For a 170V rail, a TVS clamping at 353V leaves headroom for components rated at 400V or higher.

Frequently asked questions

Does the SM15T200A have a bidirectional variant?

The SM15T200A is a unidirectional device with one channel. The SM15T series includes bidirectional variants for AC or differential-line protection, but this specific order code is single-direction only.
