SSM3K44FS from TOSHIBA, 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 | GATE | input | Gate terminal of the N-channel MOSFET; VGSS rating is ±20 V and VGS(on) must exceed Vth (0.8 to 1.5 V at VDS = 3 V, ID = 0.1 mA). |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET, shown on the equivalent circuit tied to the body diode anode. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET; VDSS is 30 V, ID is 100 mA DC and 200 mA pulsed. |
