The switch is controlled by a simple On/Off logic input (non-inverting) and requires no external Vcc supply — the gate drive is self-supplied from the load voltage, simplifying the BOM for a basic high-side-driver replacement. ## Fault protection and temperature range Three integrated fault protections — current limiting (fixed), over-temperature shutdown, and over-voltage clamp — eliminate the need for external supervisory components on the load path. The slew-rate controlled turn-on reduces EMI radiated from the load wiring. Rated for junction temperatures from -40°C to 150°C, the part suits under-hood automotive, industrial motor drives, and outdoor telecom enclosures where ambient temperatures can exceed 85°C. ## Active production and package availability Infineon lists the BTF3050TEATMA1 as Active (current production) with ROHS3 compliance. No official successor or cross-reference is published; the part is the current generation.","metaTitle":"BTF3050TEATMA1 Infineon Low-Side Power Switch – 40 mOhm, 3 A","metaDescription":"BTF3050TEATMA1 Infineon low-side power switch. 40 mOhm Rds(on), 3 A continuous, 40 V load.

The key parametric difference is Rds(on): 23 mOhm typical on the BTS142 vs 40 mOhm on the BTF3050, and the BTS142 is rated for 4.6 A continuous output vs 3 A. The BTS142 also adds an auto-restart feature.
