The Infineon BTS3125TFATMA1 is a single-channel low-side power switch in the HITFET® family. Its 108 mOhm typical on-resistance and 2 A continuous output suit the TO-252-3 (DPak) package.
The maximum load voltage is 31 V. No external Vcc supply is needed.
The part comes in a TO-252-3 (DPak) surface-mount package. The supplier device package is PG-TO252-3-313.
Yes, the part is ROHS3 Compliant per Infineon's listing.
The closest functional peer in the same HITFET® family is the BTS142DATMA1, which offers a lower 23 mOhm typical Rds(on) and a higher 4.6 A output current rating, also in a TO-252-3 package. The BTS3125TFATMA1 is the lower-current, higher-resistance option — choose the BTS142DATMA1 when the load requires more than 2 A or lower conduction loss.
