MJ15025-JSM

JSMSEMI · Bipolar (BJT) · TO-3

MJ15025-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; the datasheet limits base current IB to -5 A and emitter-base voltage VEBO to -5 V.
2 E passive Emitter; the datasheet pin-1/2 outline shows two pins, with DC current gain hFE of 15 min at IC=8 A, VCE=4 V.
3 C passive Collector, connected to the metal case/mounting flange; the datasheet gives IC of -16 A (peak -30 A) and VCEO of -200 V (MJ15023) or -250 V (MJ15025).
