MC7815BDTRKG from onsemi, in a TO-252-2(DPAK). 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	VIN	power_in	Unregulated positive input voltage. For the +15 V variant (MC7815) the recommended input range is 17.5 V to 30 V (V_IN must stay ~2.0 V above V_OUT for regulation; absolute max 35 V). A ~0.33 µF ceramic bypass cap is recommended if the device is located far from the bulk filter capacitor.
2	GND	power_in	Common ground reference shared between the input and output loops. The exposed heatsink tab (shown as terminal 4 in the case outline drawing) is internally connected to this pin, so the mounting pad is at ground potential.
3	VOUT	power_out	Regulated positive output. Nominal +15 V, ±2 % (B-grade) at I_O = 500 mA, T_J = 25 °C; delivers up to 1.0 A with adequate heatsinking (short-circuit current limit ~0.2 A at V_IN = 35 V, peak output current ~2.2 A). Output cap C_O is optional for stability but improves transient response; values below 0.1 µF may cause instability.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc7815bdtrkg.step`	119 KB	You want the bare part, or you mark your own boards.
`mc7815bdtrkg-etched.step`	2.0 MB	You want the part with `MC7815BDTRKG` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 515 faces against 83 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.
