Product details

Protection window for a 40V automotive rail

The 1.5KE47CAHA0G: Its 40.2V reverse standoff voltage sits just above a nominal 40V DC bus, while the minimum breakdown voltage of 44.7V and maximum clamping voltage of 64.8V define the protection window — the rail sees no clamping below 44.7V and is held under 64.8V during a 24A surge.

Active production, sourced per RFQ

Sourced through authorized and independent distribution channels; pricing and lead time are confirmed at quote time against the BOM quantity.

Frequently asked questions

What is the peak pulse power rating of 1.5KE47CAHA0G?

This is the standard 1.5kW rating for the 1.5KE series, meaning the device can absorb a 24A surge (at the 64.8V clamp voltage) without exceeding its thermal limits.

What automotive qualification does 1.5KE47CAHA0G carry?

AEC-Q101 qualified. This certification covers the semiconductor device reliability tests required for automotive applications — temperature cycling, high-temperature reverse bias, and ESD robustness.
