This switch integrates current limiting (fixed), over-temperature shutdown, and over-voltage clamping, so it survives shorted loads and supply transients without external clamp diodes. It is a non-inverting, high-side driver that requires no Vcc supply pin — the load voltage itself powers the internal charge pump, simplifying the BOM.
The BTS441TAKSA1 is listed as obsolete.
For a pin-compatible alternative within the PROFET family, check current Infineon high-side switch offerings with similar Rds(on) and TO-220-5 package. The replacement decision depends on the specific load current and protection requirements of your application.
