DA221TL

ROHM Semicon · Switching Diodes · SOT-416

DA221TL from ROHM Semicon, in a SOT-416. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K1 passive Cathode of diode D2 (D2 runs (3)-(1)); reverse voltage VR is 20 V max and average forward current Io is 100 mA max.
2 A2 passive Anode of diode D1 (D1 runs (2)-(3)); reverse voltage VR is 20 V max and average forward current Io is 100 mA max.
3 A1/K2 passive Common node: D1 cathode joined to D2 anode (Anode/Cathode); peak forward surge current IFSM is 300 mA max (t=1μs).

CAD (KiCad official)

  • Symbol: DA221TL
  • Footprint: Package_TO_SOT_SMD:SOT-416
  • 3D model: SOT-416, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: da221tl-etched.step / da221tl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); da221tl.step / da221tl.glb are the bare package body.

Provenance

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

  • Datasheet: ROHM Semicon datasheet (9 pp, sha256 f5a55d384fd35b18, retrieved 2026-10-21, 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).
