The onsemi 2N6284G is a monolithic NPN silicon Darlington power transistor housed in a TO-204AA (TO-3) metal package. It features a maximum collector-emitter voltage of 100 Vdc and continuous collector current of 20 Adc. The device offers high DC current gain, with a minimum of 750 at 10 Adc and 100 at 20 Adc. Total power dissipation reaches 160 W at 25°C case temperature. Operating junction temperatures range from -65°C to +200°C.
Verify the specific ordering suffix 'G' confirms lead-free status as defined by the manufacturer's soldering reference manual. Confirm the package style matches the required pin configuration for your circuit board layout. Ensure thermal management solutions account for the specified derating curve above 25°C case temperature to maintain reliability within the rated power dissipation limits.
Select this component when high current gain and robust second-breakdown performance are required for low-speed switching or amplification. Compare against complementary PNP variants like the 2N6287 if push-pull configurations are needed. Evaluate thermal resistance requirements based on the application's case temperature constraints and duty cycle specifications.
This part belongs to the 2N6284 series of complementary silicon power transistors manufactured by onsemi. It is designed alongside PNP counterparts such as the 2N6286 and 2N6287 to facilitate balanced circuit designs. The series utilizes a rugged monolithic construction to handle significant power dissipation in standard through-hole metal packages.
