# MMBT2222A_R1_00001

**PANJIT International** · Bipolar (BJT) · SOT-23

MMBT2222A_R1_00001 from PANJIT International, 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; the datasheet gives VEBO of 6 V maximum and a collector-base breakdown of 75 V minimum for this terminal's junctions. |
| 2 | E | passive | Emitter; the arrow in the top-view symbol shows current flowing out of the NPN emitter, and VEBO is rated at 6 V. |
| 3 | C | passive | Collector; rated at VCEO 40 V, VCBO 75 V and 600 mA continuous collector current. |
