AL17050WT-7

Diodes Incorporated · LED Drivers · SOT-25

AL17050WT-7 from Diodes Incorporated, in a SOT-25. 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 VCC power_in Control circuit power supply. Operating VCC 5.3-5.6V (recommended); absolute max 6.5V. Powered from an HV start-up source through the internal power block.
2 FB input Regulator feedback input. MOSFET feedback switch-on threshold VFB = 2.5V (typ). OLP feedback trigger threshold VFB_OLP = 1.7V (typ).
3 SOURCE power_in Internal power MOSFET source. Ground reference for VCC and FB pins. Pins 3 and 4 are internally tied together.
4 SOURCE power_in Internal power MOSFET source. Ground reference for VCC and FB pins. Pins 3 and 4 are internally tied together.
5 DRAIN power_in Internal power MOSFET drain. High voltage current source input. VDSS absolute max 500V; operating VDRAIN up to 400V; RDS(ON) 30Ω typ.

Two STEP files. Same geometry, different body top:

File Size Use it when
al17050wt-7.step 85 KB You want the bare part, or you mark your own boards.
al17050wt-7-etched.step 1.6 MB You want the part with AL17050WT-7 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 403 faces against 102 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: Diodes Incorporated datasheet (15 pp, sha256 a4ab568851a455dc, retrieved 2026-08-17, tier: lcsc)
  • 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).
