NCV8402ADDR2G from onsemi, 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	Source1	passive	Source of channel-1 low-side N-channel MOSFET. Typically tied to system ground (load current return, internally current-sensed for the 3.7-5.0 A current limit).
2	Gate1	input	Gate (logic-level input) of channel-1 MOSFET. Analog drive capable; VGS(th) ≈ 1.3-2.2 V, absolute max VGS = ±14 V. Drives the internal N-MOSFET on/off; overvoltage is clamped drain-to-gate for inductive-load protection.
3	Source2	passive	Source of channel-2 low-side N-channel MOSFET. Typically tied to system ground; independent from channel-1 source.
4	Gate2	input	Gate (logic-level input) of channel-2 MOSFET. Same electrical characteristics as Gate1: VGS(th) ≈ 1.3-2.2 V, VGS max ±14 V, analog drive capable.
5	Drain2	passive	Drain of channel-2 MOSFET (connects to the switched load). Internally clamped at 42 V (V(BR)DSS). Bonded to two package pins (5 and 6) to share current and improve thermal conduction - tie both to the load node.
6	Drain2	passive	Drain of channel-2 MOSFET (same net as pin 5). Second drain pin provided for current sharing and PCB heat spreading.
7	Drain1	passive	Drain of channel-1 MOSFET (connects to the switched load). Internally clamped at 42 V. Bonded to two package pins (7 and 8) for current sharing and thermal dissipation.
8	Drain1	passive	Drain of channel-1 MOSFET (same net as pin 7). Second drain pin provided for current sharing and PCB heat spreading.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ncv8402addr2g.step`	122 KB	You want the bare part, or you mark your own boards.
`ncv8402addr2g-etched.step`	2.6 MB	You want the part with `NCV8402ADDR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 643 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.
