BDW46

Single Bipolar Transistors Overview

The BDW46G is a PNP Darlington complementary silicon power transistor designed for general-purpose and low-speed switching applications. It features a maximum collector current of 15 A, a collector-emitter sustaining voltage of 80 V, and a total device dissipation of 85 W at 25°C case temperature. The component utilizes monolithic construction with built-in base-emitter shunt resistors and is housed in a TO-220 compact package.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify the specific suffix G indicates a Pb-Free and RoHS compliant package configuration. Confirm the ordering code matches the required PNP polarity variant within the BDW42/BDW46/BDW47 series. Ensure thermal management solutions align with the specified junction-to-case thermal resistance limits for reliable operation under load.

Single Bipolar Transistors Selection Notes

Select this component when a PNP Darlington configuration is required for medium-power applications. Consider the 80 V collector-emitter sustaining voltage limit and 15 A continuous collector current capability. Evaluate the thermal requirements against the 85 W dissipation rating and the necessity for built-in base-emitter shunt resistors to simplify drive circuit design.
