The BTS5012SDAAUMA1: The 12 mOhm typical Rds(on) means at 6 A continuous the I²R loss is just 0.43 W — the tab and board copper handle that without a heatsink in most layouts. The 5.5 V to 20 V load range covers 12 V and 24 V nominal rails common in automotive body controllers and industrial PLC outputs.
150 °C junction — thermal margin in hot bays
The protection set — current limiting, open load detect, over-temperature, over-voltage — lets the part survive a shorted load or a stalled motor without blowing the trace.
DPak (TO-252-5) — rework and footprint
The PG-TO252-5-11 package is a standard DPak with four leads plus the exposed tab. It reworks cleanly under hot air at 300 °C — the tab wets fast, and the four leads give you a clear pin-1 mark on the top. No Vcc supply needed — the switch is self-powered from the load voltage.
Active production — no redesign pressure
Infineon lists this PROFET as Active. The series is ROHS3 compliant.
