The 103 V clamp ensures the protected circuit sees no more than that peak during a transient, which is within the typical 100–120 V rating of downstream DC-DC converters and sensors on a 48 V rail. The 15 A peak pulse current (10/1000 µs) is the current the diode can sink while clamping at 103 V — the 1.5 kW product is the instantaneous power, not continuous. For repetitive surges, derate per the datasheet's pulse-train curve. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE75AHA0G mounts into a 1.1 mm diameter hole on a standard PCB or terminal block. The axial leads allow either through-hole soldering or point-to-point wiring in high-vibration environments. The package is not intended for high-density SMT layouts, but the large body dissipates heat well during repetitive pulse events.","metaTitle":"1.5KE75AHA0G TVS Diode, 1.5kW, 103V Clamp, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE75AHA0G automotive TVS, 1500W peak pulse, 64.1V standoff, 103V clamp, AEC-Q101, DO-201 axial.
