BTS3410G from Infineon, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	S1	power_in	Source of channel 1 power MOSFET. Connect to system ground / low-side return for channel 1 load current.
2	IN1	input	Logic-level input for channel 1 gate-driving unit. VIN(th) typ 1.7 V (1.3-2.2 V). Operating input range -0.2 V to 10 V (no current limit) with ESD protection to Source. Analog driving is possible.
3	S2	power_in	Source of channel 2 power MOSFET. Connect to system ground / low-side return for channel 2 load current.
4	IN2	input	Logic-level input for channel 2 gate-driving unit. VIN(th) typ 1.7 V (1.3-2.2 V). Operating input range -0.2 V to 10 V with ESD protection to Source. Analog driving is possible.
5	D2	output	Drain of channel 2 power MOSFET (low-side switch output for channel 2). Connect to load; load return goes to Vbb. Pins 5 and 6 are internally the same net; tie together on PCB for full current capability and heat sinking. VDS max 42 V, IDS nominal 1.3 A, RDS(on) 200 mΩ typ.
6	D2	output	Drain of channel 2 power MOSFET (same net as pin 5). Tie to pin 5 on PCB for full-current low-side switch to the channel 2 load.
7	D1	output	Drain of channel 1 power MOSFET (low-side switch output for channel 1). Connect to load; load return goes to Vbb. Pins 7 and 8 are internally the same net; tie together on PCB for full current capability and heat sinking. VDS max 42 V, IDS nominal 1.3 A, RDS(on) 200 mΩ typ.
8	D1	output	Drain of channel 1 power MOSFET (same net as pin 7). Tie to pin 7 on PCB for full-current low-side switch to the channel 1 load.

CAD (KiCad official)

Symbol: BTS3410G
Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
3D model: SOIC-8 (KiCad packages3D, STEP)

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`bts3410g.step`	122 KB	You want the bare part, or you mark your own boards.
`bts3410g-etched.step`	2.0 MB	You want the part with `BTS3410G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 484 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
