PANJIT International · Bipolar (BJT) · SOT-23
MMBT5551_R1_00101 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 of the NPN transistor; VEBO max 6 V, and the transistor has hFE of 80 min at VCE=5V, IC=1mA. |
| 2 | E | passive | Emitter of the NPN transistor; emitter-base voltage limited to 6 V. |
| 3 | C | passive | Collector of the NPN transistor; VCEO 160 V, VCBO 180 V, IC continuous 600 mA. |
