The 1500 W peak pulse rating is specified for a 10/1000 µs waveform; for shorter transients like ESD or load dump, the peak power capability is higher, but the 1500 W figure is the safe design-in limit for the standard surge waveform. ## Package and temperature range for the application Housed in a DO-201AA / DO-27 axial-lead package, it is a through-hole part suited for point-to-point wiring on terminal strips or PCB through-hole layouts where a robust mechanical anchor is needed. The operating junction temperature range spans -55°C to 175°C, covering the full automotive under-hood thermal profile — from cold-crank to hot-soak under the hood.","metaTitle":"1.5KE27CAH TVS Diode, 1500W, 23.1V Standoff, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE27CAH automotive TVS diode, 1500W peak pulse, 23.1V standoff, AEC-Q101 qualified.
