No official successor or direct-replacement order code is listed on the Infineon lifecycle record. ## 15 mOhm Rds(on) — conduction loss and heatsink budget Typical on-resistance is 15 mOhm. At the 17 A maximum output current, conduction loss hits roughly 4.3 W — that number sets the heatsinking requirement for the TO-220-5 package. The PG-TO220-5-12 footprint has a metal tab; a clip-on or screw-down heatsink is expected for sustained loads near the current ceiling. ## 4.75 V to 43 V load voltage — 12 V and 24 V rails covered The load supply range spans 4.75 V to 43 V, covering nominal 12 V and 24 V automotive and industrial buses with margin for load-dump transients. The device does not require a Vcc/Vdd supply — it is self-powered from the load rail, simplifying the gate-drive circuit. ## Integrated fault protection — fewer external components Fault protection includes current limiting (fixed), open-load detection, over-temperature shutdown, and over-voltage clamp. These replace the discrete sense resistor, comparator, and TVS diode a bare MOSFET solution would need. The Status Flag output reports fault conditions to a microcontroller or logic input. ## Through-hole TO-220-5 — rework and mechanical fit The TO-220-5 through-hole package (PG-TO220-5-12) is a five-lead variant of the standard TO-220. The through-hole leads survive multiple rework cycles under a soldering iron or hot-air station — the thermal mass of the tab is the main challenge for hand-soldering, not the leads themselves.","metaTitle":"Infineon BTS441RSBKSA1 PROFET High-Side Switch, 15 mOhm","metaDescription":"Infineon BTS441RSBKSA1 PROFET high-side power switch, 15 mOhm Rds(on), 17 A output, 4.75-43 V load range.
