AP1501-K5G-13

Diodes Incorporated · DC-DC Converters · TO-263-5

AP1501-K5G-13 from Diodes Incorporated, in a TO-263-5. 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 VIN power_in Operating voltage input. Accepts supply up to 40 V (absolute max VCC = +45 V). Bypass to GND with an input capacitor close to the pin.
2 Output output Switching output from the internal 3 A NPN switch. Connect to the external inductor / catch diode node of the buck power stage. Saturation voltage typically 1.3 V at IOUT = 3 A.
3 Gnd power_in Device ground. The metal tab of the TO263-5L package is internally tied to Gnd and should be soldered to a ground copper pour for thermal dissipation (θJA ≈ 37 °C/W for TO263-5).
4 FB input Output voltage feedback control input. Internal reference VFB = 1.23 V; for the adjustable version set VOUT = VFB × (1 + R1/R2) with R2 = 1 k-3 k. Feedback bias current typically 40 nA (max 100 nA over temperature).
5 SD input ON/OFF shutdown logic input. VIL ≤ 0.6 V keeps the regulator ON; VIH ≥ 2.0 V forces the regulator OFF (standby). Absolute max input range −0.3 V to +40 V. Can be paired with an external RC (e.g. 0.1 µF + 10 k) for a delay-start.

  • 3D model files: ap1501-k5g-13-etched.step / ap1501-k5g-13-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap1501-k5g-13.step / ap1501-k5g-13.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ap1501-k5g-13.step 180 KB You want the bare part, or you mark your own boards.
ap1501-k5g-13-etched.step 2.1 MB You want the part with AP1501-K5G-13 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 569 faces against 135 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.
