The DO-201 body handles the 1500W pulse without exceeding the junction temperature limit of 175°C, provided the lead length and PCB copper area offer adequate heat sinking. The axial form factor allows hand insertion or wave solder; the leads are tin-plated for compatibility with standard solder processes. No power line protection feature is implemented — this is a dedicated transient suppressor, not a crowbar or foldback device.","metaTitle":"1.5KE250CH Taiwan Semiconductor Zener TVS, 1500W, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE250CH Zener TVS, bidirectional, 1500W peak pulse, 202V standoff, AEC-Q101 automotive grade.
