MJ15004

SPTECH · Pre-ordered transistors · TO-3

MJ15004 from SPTECH, 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	BASE	input	Base of the PNP transistor; absolute maximum continuous base current is -5 A and emitter-base voltage is -5 V.
2	EMITTER	passive	Emitter of the PNP transistor; VEBO is limited to -5 V.
3	COLLECTOR	passive	Collector, connected to the TO-3 case; rated for -140 V (VCBO/VCEO) and -20 A continuous collector current.
