hongjiacheng · Bipolar (BJT) · SOT-363
MMDT2227 from hongjiacheng, in a SOT-363. 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 | E1 | passive | Emitter of the PNP transistor (VEBO -5.0V max, IC -0.6A max, per function diagram). |
| 2 | B1 | input | Base of the PNP transistor (VCBO/VCEO -60V max, hFE 100-300 at IC=-150mA, VCE=-10V). |
| 3 | C2 | passive | Collector of the NPN transistor (VCBO 75V, VCEO 40V max, IC 0.6A max). |
| 4 | E2 | passive | Emitter of the NPN transistor (VEBO 6.0V max, per function diagram). |
| 5 | B2 | input | Base of the NPN transistor (hFE 100-300 at IC=150mA, VCE=10V). |
| 6 | C1 | passive | Collector of the PNP transistor (VCBO/VCEO -60V max, IC -0.6A max). |
