Product details

1500W peak pulse in an axial DO-201AA body

The 1.5KE24AHE3_A/D: It clamps a 20.5V standoff rail at 33.2V during a 45.2A peak pulse (10/1000µs waveform), which means a 24V nominal supply line sees protection below the downstream component's abs-max rating.

AEC-Q101 and the 175°C junction ceiling

An engine ECU or transmission controller that sees 125°C ambient still has 50°C of margin before derating the 1500W peak pulse capability. The breakdown voltage range starts at 22.8V minimum, so a 24V nominal rail with 10% tolerance (21.6V to 26.4V) stays below the avalanche threshold during normal operation. The 33.2V clamping ceiling then limits the transient to a level a downstream 36V-rated DC-DC converter or sensor can survive.

Active production, sourced per BOM quantity

The base product number 1.5KE24 covers the full family; the AHE3 suffix denotes the AEC-Q101 automotive grade and the tape-and-box packaging.
