MJE350G from JSMSEMI, in a TO-126. 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; emitter-base voltage VEBO is -3 V max and collector current IC is -0.5 A continuous. |
| 2 | C | passive | Collector (also connected to the tab); VCBO and VCEO are -300 V, IC is -0.5 A continuous, and power dissipation is 20 W at TC=25℃. |
| 3 | B | passive | Base; the VCE(sat) is -1.0 V max at IC=-50 mA and IB=-5 mA. |
