SI0205-TP from MCC Micro Commercial Components, in a SOT-523. 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; the gate threshold VGS(th) is 0.3 V min, 0.5 V typ, 0.8 V max at VGS = VDS, ID = 250 µA. |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET, serving as the reference for VGS and the return path for drain current. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET; the drain-source breakdown voltage V(BR)DSS is 50 V min at VGS = 0 V, ID = 250 µA. |
