Product details

What this switch does in the vehicle

The Infineon BTS500151TAAATMA1 is a single-channel high-side power switch rated for 33 A continuous output, designed to drive resistive, inductive, and capacitive loads. Its load supply range spans 5.5 V to 28 V.

AEC-Q100 and the 150°C junction ceiling

Fault protection set for harsh loads

The switch integrates fixed current limiting, over-temperature shutdown, and over-voltage clamping — three protections that cover the common failure modes in automotive power distribution: a shorted lamp filament, a stalled motor, or a load-dump spike from the alternator. The non-inverting input type means the output turns on when the logic signal goes high, matching the standard ECU GPIO polarity. No external charge pump or gate-drive supply is needed because the high-side driver is self-biased from the load voltage.

The BTS500151TAAATMA1 is listed as obsolete.

The package is a TO-263-7 (D²Pak) with 6 leads plus a tab — the supplier device code is PG-TO263-7-8.

Frequently asked questions

Is BTS500151TAAATMA1 obsolete?

Yes, the BTS500151TAAATMA1 is listed as obsolete. No official replacement part number has been published by Infineon. For a BOM that requires this exact order code, the supply comes from surplus and broker-channel inventory.

Is BTS500151TAAATMA1 compatible with 12V systems?

Yes. The load supply voltage range is 5.5 V to 28 V, which covers both 12 V and 24 V automotive electrical systems. The switch operates directly from the battery rail without needing a separate Vcc supply.
