MPS651

Changjing · Bipolar Transistors - BJT · TO-92

MPS651 from Changjing, in a TO-92. 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 E passive Emitter of the NPN transistor (pin 1 of the TO-92); VEBO is 5 V max and the emitter-base breakdown voltage V(BR)EBO is 5 V min.
2 B passive Base of the NPN transistor (pin 2 of the TO-92); base-emitter saturation voltage VBE(sat) is 1.2 V max at IC=1A, IB=100mA.
3 C passive Collector of the NPN transistor (pin 3 of the TO-92); VCBO is 80 V, VCEO is 60 V and continuous IC is 2 A max.
