Active production, 1500 W bidirectional TVS for 24 V rails
The 1.5KE27CAHE3_A/C: With a 23.1 V reverse standoff voltage and a 25.7 V minimum breakdown, it clamps transients at 37.5 V maximum — a fit for protecting 24 V nominal power or signal lines in automotive and industrial systems. 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.
