The MJE5742G from ON Semiconductor is an NPN Silicon Power Darlington Transistor engineered for demanding high-voltage power switching applications within inductive circuits. This device offers a robust 400V collector-emitter sustaining voltage and a continuous collector current rating of 8A, with a peak capability of 16A.
Key electrical characteristics include a high DC current gain (hFE) of 200 at 2A and 5V, and a Vce saturation of 3V maximum at 400mA and 8A. The transistor operates across a wide temperature range from -65°C to 150°C.
Packaged in a standard TO-220-3 configuration, the MJE5742G is designed for through-hole mounting. Its thermal resistance from junction-to-case is 1.25°C/W, and junction-to-ambient is 62.5°C/W, supporting efficient heat dissipation. The device is also noted as being Pb-Free and RoHS Compliant.
Applications for the MJE5742G include small engine ignition systems, switching regulators, inverters, solenoid and relay drivers, and motor controls, where its high voltage and current handling capabilities are beneficial.
