The 1.5KE440CAH: Listed as Active — the manufacturer is still running this part, so authorized-channel orders are the normal path. No last-time-buy window or NRND flag to chase. The AEC-Q101 cert gives you the paperwork trail for PPAP submissions — date codes, lot traceability, and the reliability report are available from the factory through the supply chain.
AEC-Q101 certifies the part for automotive applications — it has passed the stress tests for temperature cycling, high-temperature reverse bias, and ESD immunity required for under-hood or chassis-mounted electronics.
The diode clamps at 602 V maximum when hit with a 2.5 A peak pulse current (10/1000 µs waveform). The breakdown voltage starts at 418 V minimum, and the reverse standoff is 376 V typical.
