Technical Details & Description

What this HITFET switch does on your board

The Infineon BTS3104SDLATMA1 is a single-channel low-side N-channel power switch from the HITFET family, designed for general-purpose on/off switching of resistive and inductive loads up to 2 A continuous. The 104 mOhm typical Rds(on) keeps conduction losses low enough that a TO-252-3 (DPak) footprint handles the heat without a dedicated heatsink in most environments. Input is non-inverting, and the switch does not require a Vcc supply — it is self-powered from the load voltage, which simplifies the wiring in automotive and industrial panels.

Active, no LTB worry

Frequently asked questions

What is the replacement for BTS3104SDLATMA1?

The BTS142DATMA1 is a higher-current (4.6 A) HITFET low-side switch with a lower 23 mOhm Rds(on) and a 42 V load voltage rating. It shares the same non-inverting input, N-channel output, and TO-252-3 footprint, but the higher current and lower on-resistance make it a functional upgrade for designs that need more load headroom or lower dissipation. Verify pin compatibility for your specific layout.

Is BTS3104SDLATMA1 compatible with 3.3V logic?

Yes, the input is non-inverting and does not require a Vcc supply, so it can be driven directly by 3.3 V logic as long as the logic high level exceeds the switch's input threshold. The datasheet threshold values should be checked against your logic family's output voltage.
