The breakdown voltage range starts at 71.3V minimum — this is where the device begins to avalanche. A downstream DC-DC converter with a 100V abs-max input rating would be marginal here; a 120V-rated part gives comfortable margin. The 1500W rating is specified at 25°C; derate linearly above that per the datasheet curve, typically losing about 0.1%/°C above 25°C. ## DO-201 axial package — board-fit and thermal considerations Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE75CA B0G is a through-hole part intended for point-to-point wiring or PCB mounting with 0.040-inch diameter leads. The axial form factor conducts heat out through the leads — adequate copper pad area or lead length on each side is needed to keep junction temperature within limits during repetitive surge events. Supplied in bulk packaging, not tape-and-reel — factor this into pick-and-place planning if you are using it in high-volume production; a tube or tray feeder is not available.","metaTitle":"1.5KE75CA B0G TVS Diode, 1500W, 103V Clamp, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE75CA B0G bidirectional TVS, 1500W peak pulse, 103V clamping, DO-201 axial.
