33A high-side switch for automotive power distribution
The Infineon BTS500151TMAAKSA1 is a single-channel, high-side power switch rated for continuous output current up to 33A across a load voltage range of 5.5V to 28V. It integrates an N-channel MOSFET with on/off control through a non-inverting input and requires no external Vcc supply.
Load budget and fault protection in the TO-220-7 package
The 33A maximum output current defines the continuous load ceiling for a single channel. In a 12V nominal system, that translates to nearly 400W of switched power — enough for high-current solenoids, DC motors, or resistive heater loads. The package is PG-TO220-7-232, a through-hole formed-leads variant of the TO-220 outline. Integrated fault protection covers current limiting (fixed threshold), over-temperature shutdown, and over-voltage clamping. These protections reduce the need for external sense resistors, comparators, or TVS diodes on the output, saving board area and BOM cost in space-constrained modules like engine-control units or transmission controllers.
NRND — plan the last-time buy or identify a replacement
Infineon lists the BTS500151TMAAKSA1 as Not Recommended for New Designs (NRND). This means the part remains available for existing production but is in the phase-out pipeline. Buyers with active BOM lines should evaluate a last-time-buy quantity or qualify a pin-compatible alternative from the same PROFET family to avoid a supply gap.
