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.","metaTitle":"STMicroelectronics SM15T200A TVS Diode, 1500W, 171V Standoff","metaDescription":"SM15T200A Zener TVS diode from STMicroelectronics, 1500W peak pulse power, 171V reverse standoff, 353V clamping.
