BD546-S

Overview

The BD546-S is a Darlington transistor manufactured by Bourns Inc. It features an NPN configuration with a voltage rating of 100V and a current capacity of 4A. The component is supplied in a reel package format. This specific part number is currently listed as obsolete or end-of-life within the manufacturer's distribution channels.

Feature Summary

High current handling capability suitable for power switching applications
Integrated Darlington structure providing high gain
Robust voltage rating for industrial environments

Applications

Industrial motor control systems
Power supply output stages
General purpose switching circuits

Procurement Notes

Verify availability through authorized distributors as this component is marked as obsolete. Confirm exact packaging specifications and lead times with suppliers, as stock levels fluctuate. Ensure compatibility with existing board designs before procurement due to potential lifecycle restrictions.

Selection Notes

Consider alternative active Darlington transistors from the same family if long-term supply stability is required. Evaluate thermal management requirements given the 4A current rating. Verify pinout compatibility with legacy designs when selecting substitutes.

Part Context

This component belongs to Bourns' discrete semiconductor portfolio, specifically within the transistor category. It represents a legacy product line often found in older industrial equipment designs. The manufacturer continues to support documentation but has ceased new production allocations.

Replacement Considerations

Check for direct cross-references such as BDW54 variants. Consult official substitution guides for equivalent NPN Darlington pairs with matching voltage and current ratings.
