BD243B-S

Overview

The BD243B-S is a general-purpose NPN bipolar junction transistor manufactured by Bourns Inc. It is housed in a TO-220 package and designed for signal amplification applications. The component features a maximum collector-emitter breakdown voltage of 80 V and a continuous collector current rating of 6 A. Key electrical specifications include a saturation voltage of 1.5 V measured at a base current of 1 A and a collector current of 6 A. The device is RoHS compliant and currently listed as an obsolete product status.

Feature Summary

NPN configuration suitable for general-purpose amplifying signals
TO-220 through-hole package design
RoHS compliant manufacturing standard

Applications

General-purpose signal amplification circuits
Switching applications within specified voltage and current limits

Procurement Notes

Verify the obsolete product status with the manufacturer or authorized distributors before procurement planning. Confirm that the TO-220 package dimensions match the target PCB footprint requirements. Ensure that the 80 V breakdown voltage and 6 A current ratings are sufficient for the specific circuit operating conditions to prevent device failure.

Selection Notes

Select this component when a general-purpose NPN transistor with moderate power handling capabilities is required. The TO-220 package provides adequate thermal dissipation for higher current loads compared to smaller surface-mount alternatives. Consider the 80 V collector-emitter voltage limit to ensure compatibility with the system's supply voltage levels.

Part Context

This part belongs to the BD243x series of single bipolar transistors from Bourns Inc. The series includes complementary PNP variants such as the BD213, offering flexibility for push-pull amplifier configurations. The BD243B-S specifically denotes the NPN variant within this family, standardized for industrial and consumer electronic designs requiring reliable switching performance.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the obsolete status of the component. Engineers should consult official cross-reference lists from Bourns Inc. or authorized distributors for compatible replacements.
