FMMT6517TA from Diodes Incorporated, in a SOT-23. 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 | B | passive | Base terminal; the datasheet limits base current to 25 mA (IB) and emitter-base voltage to 7 V (VEBO). |
| 2 | E | passive | Emitter terminal; the datasheet limits emitter-base voltage to 7 V (VEBO) and the emitter-base breakdown to a minimum of 7 V at IE = 100µA. |
| 3 | C | passive | Collector terminal; the datasheet limits collector-emitter voltage to 350 V (VCEO) and collector current to 500 mA (IC). |
