MMBTA56Q-7-F 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; the top-view pin-out drawing shows B at the lower-right lead, and VEBO is -4.0 V maximum. |
| 2 | E | passive | Emitter of the PNP transistor; the top-view pin-out drawing shows E at the upper-right lead. |
| 3 | C | passive | Collector of the PNP transistor on the single lead; VCEO is -60 V (MMBTA55) or -80 V (MMBTA56), and continuous IC is -500 mA. |
