1500 W peak pulse, AEC-Q101, 40.2 V standoff
The 1.5KE47AHB0G: The 40.2 V reverse standoff voltage (working voltage) lets this part sit across a 36 V or 40 V nominal rail without conducting in normal operation, while the 44.7 V minimum breakdown voltage ensures the avalanche triggers before the downstream circuitry sees damaging overvoltage. The through-hole DO-201AA (DO-27 axial) package handles the thermal dissipation of repeated surge events without derating at elevated ambient temperatures.
Automotive grade and active lifecycle
It is intended for use in engine control units, transmission controllers, ABS modules, and other safety-critical automotive electronics where a single transient failure cannot be tolerated.
