BD140-6-BP

Overview

The BD140-6-BP is a PNP silicon epitaxial planar transistor manufactured by Micro Commercial Components. It features a collector-emitter voltage of -80 V and a continuous collector current of -1.5 A. The device offers a DC current gain range of 100 to 250 in the Rank 6 classification. It is housed in a TO-220 package with a maximum power dissipation of 12.5 W at 25°C ambient temperature.

Feature Summary

• Utilizes an epitaxial planar silicon structure for reliable performance
• Provides high DC current gain suitable for amplifier applications
• Encapsulated in epoxy meeting UL 94 V-0 flammability rating

Applications

• General-purpose amplification circuits
• Driver stages for power transistors
• Audio frequency signal processing

Procurement Notes

Verify authenticity through authorized distributors or direct MCC channels to ensure traceability and quality standards. Confirm the specific suffix requirements, such as adding '-HF' for halogen-free versions if mandated by project specifications. Ensure the bulk packaging format aligns with assembly line handling capabilities.

Selection Notes

Select this component when an -80 V PNP transistor with moderate current handling is required. The Rank 6 hFE classification ensures consistent gain characteristics for linear applications. Consider thermal management strategies given the 12.5 W dissipation limit in free air environments.

Part Context

This part belongs to the BD136/138/140 series of complementary NPN/PNP transistors. It serves as the PNP counterpart to the BD139. The series is designed for general-purpose switching and amplifying tasks, offering robust construction within standard plastic packages.

Replacement Considerations

Direct functional substitutes include the BD139-6 from other manufacturers, provided voltage and current ratings match. Verify pinout compatibility and thermal resistance values before substitution.
