MJ15025G-JSM from JSMSEMI, in a TO-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 | B | input | Base pin; the datasheet rates base current at -5 A and VEBO at -5 V (open collector). |
| 2 | E | passive | Emitter pin, shown with the arrow on the PNP symbol; the datasheet rates VEBO at -5 V (open collector). |
| 3 | C | passive | Collector, connected to the metal case/flange; the datasheet rates IC at -16 A (-30 A peak) and VCEO at -250 V for MJ15025. |
