MJL21194G

onsemi · Bipolar (BJT) · TO-264-3

MJL21194G from onsemi, in a TO-264-3. 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 BASE input Base terminal of the NPN MJL21194; the datasheet gives a maximum continuous base current IB of 5 Adc.
2 COLLECTOR passive Collector terminal of the MJL21194; the datasheet gives VCEO 250 Vdc, continuous collector current IC 16 Adc, and peak collector current ICM 30 Adc.
3 EMITTER passive Emitter terminal of the MJL21194; the datasheet gives an emitter-base voltage VEBO of 5 Vdc.
