TCAN1051HGDR from Texas Instruments, 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	TXD	input	CAN transmit data input from the host controller. LOW drives a dominant bus state; HIGH allows the recessive state. Internal pull-up biases the bus to recessive if left floating. Logic input voltage range -0.3 V to VIO+0.3 V (max +7 V).
2	GND	power_in	Device ground reference. All voltage measurements are referenced to this terminal.
3	VCC	power_in	Transceiver 5 V supply voltage. Recommended operating range 4.5 V to 5.5 V; absolute maximum 7 V. Decouple to GND with local bypass capacitors.
4	RXD	output	CAN receive data output to the host controller. LOW indicates a dominant bus state; HIGH indicates recessive. Output current rated ±8 mA max; drives to VCC rail on non-'V' variants.
5	NC	unconnected	No Connect on the HG (non-'V') variant. Pin 5 is repurposed as VIO only on devices with the 'V' suffix; on TCAN1051HG it has no internal connection and may be left floating or tied to GND.
6	CANL	bidirectional	Low-side CAN differential bus I/O. Together with CANH forms the twisted-pair CAN bus. HG variant supports ±70 V bus fault protection and ±16 kV HBM ESD to GND.
7	CANH	bidirectional	High-side CAN differential bus I/O. Together with CANL forms the twisted-pair CAN bus. HG variant supports ±70 V bus fault protection and ±16 kV HBM ESD to GND.
8	S	input	Silent (listen-only) mode control input, active HIGH. Drive LOW for normal mode; drive HIGH to place the transceiver in silent mode where the transmitter is disabled but the receiver remains active. Logic input voltage range -0.3 V to VIO+0.3 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tcan1051hgdr.step`	122 KB	You want the bare part, or you mark your own boards.
`tcan1051hgdr-etched.step`	2.1 MB	You want the part with `TCAN1051HGDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 546 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.
