Its load supply range spans 5.5 V to 28 V. ## AEC-Q100 and the 150°C junction ceiling This part carries an AEC-Q100 qualification, meaning it has passed the automotive stress tests for production vehicle programs — thermal shock, high-temperature operating life, and humidity bias. At 150°C junction, the 33 A rating must be derated per the datasheet's SOA curve; the package's thermal pad in the PG-TO263-7-8 case is the primary heat path to the PCB copper plane. ## 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. For a BOM line that still calls out this exact order code, the supply path runs through independent distribution and surplus inventory. ## Package and footprint for the layout The package is a TO-263-7 (D²Pak) with 6 leads plus a tab — the supplier device code is PG-TO263-7-8. The exposed tab on the bottom is the drain connection and the primary thermal path; the PCB footprint must include a copper pad and thermal vias to the ground plane to keep the junction temperature below 150°C at full load. The part is surface-mount and ships on Tape & Reel, which is the standard format for automated pick-and-place in automotive module assembly.","metaTitle":"BTS500151TAAATMA1 High-Side Power Switch, 33A, AEC-Q100","metaDescription":"Infineon BTS500151TAAATMA1 automotive high-side power switch, 33A max output, 5.5V-28V load range, AEC-Q100.
