It is used in compatible high-power audio, linear amplifier and power-control circuits. Select it using the complete circuit requirements and the datasheet for the actual manufacturer supplied.\u003c\/p\u003e\n\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDevice:\u003c\/strong\u003e MJ15012 PNP bipolar power transistor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage:\u003c\/strong\u003e TO-3 \/ TO-204AA metal case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector-emitter voltage:\u003c\/strong\u003e 250 V maximum magnitude in the onsemi reference datasheet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector current:\u003c\/strong\u003e 10 A continuous maximum rating, subject to safe operating area and cooling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower dissipation:\u003c\/strong\u003e 200 W maximum at a case temperature of 25°C; derating and an appropriate heatsink are required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplementary device:\u003c\/strong\u003e MJ15011 NPN in the reference datasheet; not included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e One transistor per unit ordered; bulk photos illustrate the component.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSelection and Installation\u003c\/h2\u003e\u003cp\u003eThe voltage, current and power limits are separate maximum ratings and cannot be assumed simultaneously. Check the safe operating area, drive requirements, gain, thermal design and pinout before replacement. The metal case is the collector in the reference TO-3 pinout; use the correct insulator and mounting hardware if isolation from the heatsink is needed. Manufacturer markings and batch details should be confirmed when a specific brand or origin is required.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eIs MJ15012 PNP or NPN?\u003c\/h3\u003e\u003cp\u003eMJ15012 is a PNP bipolar transistor.\u003c\/p\u003e\n\u003ch3\u003eWhat package does it use?\u003c\/h3\u003e\u003cp\u003eIt uses a metal TO-3 package, also designated TO-204AA.\u003c\/p\u003e\n\u003ch3\u003eCan it handle 250V and 10A at the same time?\u003c\/h3\u003e\u003cp\u003eDo not assume that. Use the safe operating area curves and thermal limits for the actual device and circuit.\u003c\/p\u003e\n\u003ch3\u003eDoes 200W mean it works without a heatsink?\u003c\/h3\u003e\u003cp\u003eNo. The rating is specified with the case held at 25°C.
