Product details

190 mOhm Rds(on) — sizing the load budget

The BTS410F2 E3043: The BTS410F2 is a single-channel PROFET high-side power switch from Infineon. Its 190 mOhm typical Rds(on) at 1.6 A max output sets the conduction loss floor.

The load supply range spans 4.7 V to 42 V. No external Vcc supply is needed — the switch is self-powered from the load rail.

Fault protection set — why you pick a smart switch over a bare MOSFET

The auto-restart feature re-enables the output after a fault clears, which is useful for driving lamps or solenoids that present a cold-start inrush.

Temperature grade and package — where it fits physically

The TO-220-5 through-hole package (P-TO220-5) provides a direct thermal path to a heatsink or chassis ground plane.

Obsolete — planning the BOM transition

Infineon lists the BTS410F2 as obsolete. For new designs or long-term production, a pin-compatible PROFET replacement should be qualified against the load current and protection requirements.

Frequently asked questions

What is the Rds(on) of BTS410F2 E3043?

The typical Rds(on) is 190 mOhm. This is the on-resistance at nominal operating conditions — actual resistance rises with junction temperature per the normalised curve in the PROFET datasheet.
