The clamping voltage at peak current is 23.5 V max, so downstream components rated for 30 V or higher have margin. ## Automotive qualification and temperature envelope The operating junction temperature range spans -55°C to 175°C, covering under-hood and engine-bay ambient conditions where the TVS must survive both cold cranking and hot soak. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE16CH is a through-hole part. The DO-201 footprint is standard — the anode and cathode bands are marked on the body; for bidirectional parts the marking is symmetric. The axial leads handle the pulse current without trace lift-off, but the board-side copper pad area under the body should be kept clear of large planes to avoid thermal coupling that could shift the clamping threshold during repetitive surges.","metaTitle":"1.5KE16CH Taiwan Semiconductor Zener TVS, 1500W, DO-201","metaDescription":"1.5KE16CH bidirectional Zener TVS, 1500W peak pulse, 12.9V standoff, AEC-Q101 automotive grade.
