BDW42

Single Bipolar Transistors Overview

The BDW42 is an NPN silicon Darlington power transistor manufactured by onsemi. It features a collector-emitter sustaining voltage of 100 Vdc and a maximum continuous collector current of 15 Adc. The device provides high DC current gain, typically 2500 at 5.0 Adc, with a minimum of 250 at 10 Adc. Total device dissipation reaches 85 W at 25°C case temperature. It operates within a junction temperature range of -55°C to +150°C and utilizes a TO-220 package.

Single Bipolar Transistors Feature Summary

• Monolithic construction with built-in base-emitter shunt resistors
• High DC current gain suitable for general purpose switching
• Low collector-emitter saturation voltage
• Pb-Free and RoHS compliant

Single Bipolar Transistors Applications

• General purpose switching applications
• Low speed switching applications

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix (e.g., G) against the manufacturer's official documentation to confirm lead-free status and packaging details. Confirm that the component meets all applicable environmental compliance standards required for the intended deployment environment before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component for circuits requiring high current handling capabilities up to 15 Amperes. Ensure adequate thermal management is implemented to maintain case temperatures within limits, as power dissipation decreases significantly above 25°C. Verify that the drive circuitry can supply sufficient base current to achieve the specified low saturation voltage levels.

Single Bipolar Transistors Part Context

This part belongs to the BDW42G/BDW46G/BDW47G complementary Darlington transistor series from onsemi. The BDW42 specifically represents the NPN variant within this lineup, designed to pair with PNP counterparts like the BDW47 for push-pull configurations in medium-power electronic systems.

Single Bipolar Transistors Replacement Considerations

The BDW46G and BDW47G are documented complementary devices within the same series. Verify pinout compatibility and polarity requirements when considering these alternatives.
