The 2SJ407 is documented in this 398 KB PDF, catalogued as a schematic though it is a component datasheet by name. In JIS naming the 2SJ series are P-channel FETs, frequently used as high-side switches and in complementary output stages. No manufacturer, package or revision is given. Use the document to confirm gate, drain and source positions, maximum ratings and on-resistance, and compare those values carefully when picking a substitute for a shorted or open transistor found during diagnosis.
