The 25.2 V maximum clamping voltage limits the transient overvoltage seen by downstream components — a 24 V nominal automotive bus with 36 V load-dump peaks stays within the TVS clamp. Peak pulse current of 59.5 A (10/1000 µs) defines the surge capability for a single event. The 1500 W rating is derated linearly above 25°C; at 175°C junction the derated power is approximately 25% of the 25°C rating, so the thermal impedance of the PCB copper and the duty cycle of the transient must be factored into the application. ## Package and board integration Housed in the DO-201AA (DO-27) axial-lead package, the 1.5KE18AHE3_A/D is a through-hole device. The axial leads are tin-plated copper; the body is molded epoxy with a flammability rating per UL 94 V-0. Lead spacing and body diameter follow the JEDEC DO-201 outline, compatible with standard 1.0 mm diameter PCB holes on a 10 mm lead-to-lead pitch. The Tape & Box (TB) packaging option is intended for hand-insertion or semi-automated assembly lines that feed axial components from a box rather than a reel. For high-volume wave-solder lines, the same device is also available in tape-and-reel format under the base product number 1.5KE18.","metaTitle":"Vishay 1.5KE18AHE3_A/D TVS Diode, 1500W, 15.3V Standoff","metaDescription":"Vishay 1.5KE18AHE3_A/D automotive AEC-Q101 TVS, 1500W peak pulse, 15.3V reverse standoff, DO-201AA axial.
