The 1.5KE440CA-AT/B: The Automotive grade and AEC-Q101 qualification certify this TVS for the -55°C to 150°C junction temperature range required in under-hood and chassis-mounted ECU applications. The qualification covers the full reliability stress battery — temperature cycling, high-temperature reverse bias, and ESD robustness — so a single qualification report covers the device for PPAP submission. Bidirectional clamping means one device handles both positive and negative transients on the same rail.

The through-hole mounting suits point-to-point wiring on terminal blocks or PCB through-hole layouts where surface-mount TVS packages would be mechanically stressed by the leaded wire bonds. The 418V minimum breakdown guarantees the avalanche threshold across the full temperature range.
