High-side switch for demanding loads
The Infineon BTS500551TMAATMA1 is a PROFET® high-side N-channel power switch rated for a continuous load voltage from 5 V to 34 V. It delivers a single output with a typical Rds(on) of 4.4 mOhm and a maximum current capability of 70 A, making it suited for high-current automotive and industrial loads such as motors, solenoids, and resistive heaters.
Fault protection and thermal range
Built-in fault protection covers current limiting (fixed), open load detection, over-temperature, and over-voltage events — the switch auto-restarts after a fault clears.
Housed in a TO-263-8 D²Pak (7 leads plus tab) with a surface-mount footprint. The PG-TO220-7-4 supplier device package is a through-hole alternative variant — confirm the exact package code on your BOM line before ordering.
Last Buy — final procurement window
This means Infineon has announced end-of-life for this order code and the final purchase window is open. No official successor is listed on the record.
