Automotive-grade transient suppressor for 48V rail protection
The 1.5KE56CAH: Its 47.8V reverse standoff voltage sits below the rail's steady-state maximum, so it stays out of conduction during normal operation. With a peak pulse power rating of 1500W (10/1000µs waveform) and a clamping voltage of 77V at 20A peak pulse current, this part shunts surge energy away from downstream electronics during load-dump or inductive kickback events. The 53.2V minimum breakdown voltage ensures the avalanche region is reached before the clamping threshold.
AEC-Q101 qualification and temperature range
AEC-Q101 qualification means this diode has passed automotive-grade stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness per the standard's reliability flow. The Automotive grade designation confirms that production parts are subject to PPAP documentation and change notification per IATF 16949 requirements — a hard requirement for Tier-1 supplier BOMs.
