Diodes Incorporated · Bipolar (BJT) · SOT-23
FMMT720TA 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 | input | Base of the PNP transistor; drive current into this pin sets the collector current (IB max -500mA, VEBO -7V). |
| 2 | E | passive | Emitter of the PNP transistor; emitter-base voltage is limited to -7V (VEBO). |
| 3 | C | passive | Collector of the PNP transistor (single lead on one side of the package); VCEO -40V, IC -1.5A continuous, ICM -4A peak. |
