The single bidirectional channel clamps both positive and negative surges, so one device replaces two unidirectional TVS diodes in series-opposing configuration. ## AEC-Q101 qualification and 175 °C junction rating The -55 °C to 175 °C operating junction temperature range covers engine-bay ambient and self-heating during repetitive surge events without derating the peak pulse power below the 1500 W rating. ## DO-201AA axial package and through-hole mounting Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE27CAHE3_A/C mounts through-hole — suited for point-to-point wiring on terminal boards or retrofitting into existing PCB layouts where a surface-mount TVS would not fit the hole pattern. The 40 A peak pulse current rating (10/1000 µs) at the 37.5 V clamping voltage confirms the device can absorb the surge energy without exceeding the package's thermal limits.","metaTitle":"Vishay 1.5KE27CAHE3_A/C TVS, 1500W, 23.1V, AEC-Q101","metaDescription":"Active Vishay 1.5KE27CAHE3_A/C bidirectional TVS diode, 1500W peak pulse, 23.1V standoff, AEC-Q101 automotive grade.
