BDW42G Description

Short technical summary and product information.

The BDW42G is an NPN Darlington silicon power transistor from On Semiconductor, designed for general purpose and low speed switching applications. Key electrical characteristics include a maximum collector-emitter voltage (VCEO) of 100V, a continuous collector current (IC) of 15A, and a power dissipation of 85W at case temperature 25°C. The device offers high DC current gain with a minimum hFE of 1000 at Ic=5A, Vce=4V and 250 at Ic=10A, Vce=4V. Low collector-emitter saturation voltage is specified as 2V max at 5A and 3V max at 10A.

 

The transistor features monolithic construction with built-in base-emitter shunt resistors, enhancing turn-off performance. It is supplied in a TO-220-3 through-hole package, suitable for mounting on a heatsink. The junction-to-case thermal resistance is 1.47°C/W, and the operating junction temperature range is -55°C to 150°C. The device is Pb-free and RoHS3 compliant, meeting the latest environmental standards.

 

Typical applications include power switching circuits, motor control, and high current amplification stages. The BDW42G is part of a complementary series with PNP types BDW46G and BDW47G, enabling design flexibility in push-pull configurations.
