MMDT2227

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).
