**Diodes Incorporated** · Bipolar (BJT) · SOT-323

MMSTA06-7-F from Diodes Incorporated, in a SOT-323. 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 terminal of the NPN transistor; the diagram shows it at the lower left of the top view, and V(BR)EBO is 4.0V min (VEBO max 4.0V). |
| 2 | E | passive | Emitter terminal of the NPN transistor; the diagram shows it at the lower right of the top view, and VEBO is rated 4.0V. |
| 3 | C | passive | Collector terminal of the NPN transistor, the single pin on the top side of the package; MMSTA06 is rated VCEO 80V and VCBO 80V, with continuous IC of 500mA. |
