Product details

1500 W peak pulse, DO-214AB, AEC-Q101 qualified

The 1.5SMC15CAHR7G: With a 12.8 V reverse standoff voltage and a 21.2 V clamping point at 74 A peak pulse current, this part protects 12 V automotive rails from load-dump and inductive-load transients. The -55°C to 150°C junction temperature range covers under-hood and engine-bay thermal profiles.

AEC-Q101 qualification and package fit

The DO-214AB (SMC) package footprint is standard for 1500 W TVS diodes, with a copper pad area under the cathode tab that sets the junction-to-ambient thermal resistance.
