Automotive-grade transient suppressor for 376 V rails
The 1.5KE440AHB0G: It clamps transients at 602 V maximum, handling a peak pulse current of 2.5 A. This part carries AEC-Q101 qualification, making it suitable for automotive electronics where reliability under load-dump and inductive-switching surges is required.
Clamping voltage and breakdown margin
This margin ensures the TVS absorbs the surge energy without letting the protected rail exceed the downstream device's absolute maximum rating. The AEC-Q101 grade guarantees the part has passed the stress tests (H3TRB, temperature cycling, ESD) required for automotive PPAP submission.
Through-hole axial package for high-reliability assembly
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE440AHB0G is supplied in bulk (loose parts). The through-hole form factor allows hand-soldering or wave-soldering and provides a robust mechanical connection for high-vibration applications. The bulk packaging is typical for MRO stock or low-volume production runs where tape-and-reel handling is not needed.
