SN6501DBVR from Texas Instruments, in a SOT-23-5. 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	D1	output	Open-drain output 1. Drives one end of the center-tapped transformer primary; internal N-channel switch pulls this pin to GND during its half-cycle. Peak switch current 500 mA max, VDS up to 14 V max.
2	VCC	power_in	Supply voltage input, 3.3 V or 5 V (absolute max 6 V). Also connects to the transformer primary center-tap. Buffer with a 1 µF to 10 µF ceramic capacitor to GND.
3	D2	output	Open-drain output 2. Drives the opposite end of the center-tapped transformer primary; complementary to D1 with break-before-make between switches. Peak switch current 500 mA max, VDS up to 14 V max.
4	GND	power_in	Device ground. Connect to board ground; both GND pins (4 and 5) must be tied to system ground.
5	GND	power_in	Device ground. Connect to board ground; both GND pins (4 and 5) must be tied to system ground.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn6501dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn6501dbvr-etched.step`	2.0 MB	You want the part with `SN6501DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 486 faces against 102 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.
