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). |
