Product details

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.

31 V load rating and temperature range — bus and environment fit

The maximum load voltage is 31 V. No external Vcc supply is needed.

Package and footprint — TO-252-3 (DPak)

The part comes in a TO-252-3 (DPak) surface-mount package. The supplier device package is PG-TO252-3-313.

Frequently asked questions

Is BTS3125TFATMA1 RoHS compliant?

Yes, the part is ROHS3 Compliant per Infineon's listing.

What is the equivalent or replacement for BTS3125TFATMA1?

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.
