MC7815BDTRKG

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)

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.

CAD (KiCad official)

  • Symbol: MC7815BDTRKG
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252-2(DPAK) (KiCad packages3D, STEP)
  • 3D model files: mc7815bdtrkg-etched.step / mc7815bdtrkg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc7815bdtrkg.step / mc7815bdtrkg.glb are the bare package body.

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.
