Product details

40 mOhm low-side switch with integrated protection

The BTF3050TEATMA1 is a single-channel N-channel low-side power switch from Infineon, designed for general-purpose switched loads up to 3 A continuous. 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.

Frequently asked questions

Does BTF3050TEATMA1 have overcurrent protection?

Yes — the device includes fixed current limiting as part of its integrated fault protection set, alongside over-temperature and over-voltage protection.

What is the closest functional second-source for BTF3050TEATMA1?

Infineon's BTS142DATMA1 (HITFET® series) is the nearest functional peer: it is also a single low-side N-channel switch with On/Off interface, non-inverting input, and the same fault protection set. 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. Package and pinout differ — confirm the PCB footprint before substituting.
