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 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.
