| Market Reality | - | The TIP142 NPN and TIP147 PNP are the 10A complementary Darlingtons of audio output stages, solenoid and relay drivers, and the lamp and motor outputs of industrial gear: 100V, 10A, 125W in the TO-247 body, with a current gain of 1000 that turns a milliampere of base current into amperes at the load. That gain is the entire design contract - circuits built around it deliver almost no drive, which is why the classic repair failure happens when a well-meaning substitution fits a genuine, expensive, "better" power transistor with gain 100 and the output stage quietly starves. Since the old TO-218 body was discontinued in 2012, TO-247 is the only current home, including the onsemi MJH6284/MJH6287 pair. |
