Infineon lists the BTS3118DATMA1 as Active. The ROHS3 compliance matches current environmental requirements for EU and most global markets.
The part ships in a TO-252-3 (DPak) surface-mount package with two leads plus a tab (SC-63 variant). The supplier device package code is PG-TO252-3-11.
The typical on-resistance is 70 mOhm. This is the value that determines conduction loss at a given load current — at 2.4 A, expect roughly 0.4 W dissipation in the switch.
The switch integrates current limiting (fixed), over-temperature shutdown, and over-voltage protection. No external sense resistor or comparator is needed for these basic fault responses.
