Product details

1500W Zener TVS for 376V automotive rails

The 1.5SMC440AHE3_AIH: Its 376V reverse standoff voltage makes it suitable for clamping transients on 24V or 48V automotive power buses where the working rail sits at 376V or below. This window protects downstream electronics from load-dump and inductive spikes without nuisance triggering on normal bus ripple.

AEC-Q101 qualification and temperature range

Qualified to AEC-Q101, this part is rated for automotive stress tests including temperature cycling, high-temperature reverse bias, and ESD robustness. No power line protection feature is implemented — this is a dedicated transient clamp, not a rail-to-rail steering array.

Frequently asked questions

What automotive qualification does this TVS diode carry?

It is AEC-Q101 qualified, meaning it has passed the automotive-grade reliability tests for temperature cycling, high-temperature reverse bias, and ESD immunity required for under-hood and chassis-mounted electronics.

What package does 1.5SMC440AHE3_AIH come in?

The part is packaged on tape and reel for automated pick-and-place assembly.
