BD546B-S

Overview

The BD546B-S is a Darlington transistor manufactured by Bourns Inc. It is an NPN type device rated for 100V collector-emitter voltage and 4A continuous collector current. The component is supplied in a reel package format. This specific part number is identified as a discontinued product within the manufacturer's portfolio.

Feature Summary

High current capability suitable for power switching applications
Integrated Darlington configuration providing high gain
Robust construction designed for industrial environments

Applications

Industrial motor control circuits
Power switching modules
General purpose amplification stages

Procurement Notes

Verify availability through authorized distributors as this component is listed as discontinued. Confirm exact datasheet revisions and mechanical drawings prior to integration. Ensure supply chain sources provide valid authenticity documentation given the end-of-life status of the part.

Selection Notes

Consider equivalent NPN Darlington transistors with matching 100V and 4A ratings if replacement is required. Evaluate thermal management requirements for the TO-220 or similar package style typically associated with this current class. Verify pinout compatibility with existing PCB layouts.

Part Context

This component belongs to Bourns' discrete semiconductor lineup, specifically the Darlington transistor category. It is distinct from Bourns' primary product lines such as potentiometers, encoders, and sensors, representing a specialized electronic component for circuit design rather than a passive or electromechanical control device.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Consult official manufacturer cross-reference tools for verified alternatives.
