MC7815CDTRKG

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

MC7815CDTRKG 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 supply. Must remain typically 2.0 V above the +15 V output (i.e. Vin >= ~17.3 V) and up to 35 Vdc absolute maximum. A 0.33 uF input bypass capacitor is required if the device is more than a few inches from the bulk supply filter.
2 GND power_in Common ground reference for both input and output. In the DPAK-3 (DT SUFFIX, CASE 369C) package this pin is electrically bonded to the heatsink tab (mechanical terminal 4), so the exposed pad must be tied to the same ground net.
3 Vout power_out Regulated +15 V output, capable of >1.0 A with adequate heatsinking (peak current 2.2 A typ). Output accuracy is +/-4% (MC7815C). An output capacitor (Co, ~0.1 uF or larger) is not required for stability but improves transient response.

Two STEP files. Same geometry, different body top:

File Size Use it when
mc7815cdtrkg.step 119 KB You want the bare part, or you mark your own boards.
mc7815cdtrkg-etched.step 1.9 MB You want the part with MC7815CDTRKG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 499 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: onsemi datasheet (31 pp, sha256 ad3f70896343dcf0, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
