Automotive transient suppressor with a 1500 W pulse rating
The 1.5KE36AHB0G: That 1.5 kW rating means it absorbs a 31 A transient pulse without failing — the clamping voltage holds at 49.9 V max under that current, so downstream silicon sees a hard voltage ceiling rather than the full surge. The reverse standoff voltage is 30.8 V, meaning the diode draws negligible leakage below that rail voltage. Breakdown starts at 34.2 V minimum, which gives a 3.4 V guard band above a nominal 28 V or 30 V supply before the TVS begins conducting.
AEC-Q101 qualification and the -55 to 175 °C operating range
This part carries AEC-Q101 automotive qualification, so it has passed the stress tests for temperature cycling, high-temperature reverse bias, and ESD robustness that production automotive modules require. The junction temperature range spans -55 °C to 175 °C, covering under-hood and engine-bay thermal profiles with margin.
DO-201 axial package and board integration
The DO-201AA (DO-27) axial-lead package is a through-hole form factor that suits point-to-point wiring or PCB mounting with 0.050-inch diameter leads. The body length and lead spacing are standard for this power class, so existing DO-201 footprints and panel-mount clips accept the part without layout changes. The 1.5 kW pulse rating is a 10/1000 µs waveform; shorter pulses (8/20 µs) allow higher peak current, but the datasheet's derating curve governs the actual margin.
