BCV47-TP

Overview

The BCV47-TP is a surface-mount NPN Darlington transistor manufactured by Micro Commercial Components. It utilizes the SOT-23 (TO-236-3) three-pin package and operates within a temperature range of -55°C to +150°C. Key electrical specifications include a maximum collector-emitter voltage of 60 V, a continuous collector current of 500 mA, and a power dissipation rating of 300 mW. The device features a transition frequency of 170 MHz and offers high DC current gain characteristics suitable for switching and amplification applications.

Feature Summary

• High current handling capability with a 500 mA continuous collector current rating
• Wide thermal operating range supporting extreme environmental conditions
• Integrated Darlington configuration providing substantial current gain
• Compact surface-mount footprint designed for automated assembly

Applications

• General-purpose signal amplification circuits
• Low-power switching applications in consumer electronics

• Audio pre-amplifier input stages

Procurement Notes

Verify component authenticity through authorized MCC distributors or certified supply chain partners. Confirm RoHS compliance status and specific tape-and-reel packaging requirements prior to order placement. Ensure storage conditions maintain moisture sensitivity levels according to manufacturer guidelines to prevent package degradation during soldering processes.

Selection Notes

Select this component when high current gain is required in a compact surface-mount form factor. The 60 V voltage rating suits low-voltage logic interfacing. Consider the 300 mW power dissipation limit for thermal management in dense PCB layouts. Evaluate the 170 MHz transition frequency against signal bandwidth requirements to ensure adequate performance for the intended application speed.

Part Context

This part belongs to the Micro Commercial Components discrete semiconductor portfolio, specifically within the bipolar junction transistor category. The BCV47-TP represents a standard industry-compatible Darlington pair solution. It serves as a fundamental active component for analog and digital circuit designs requiring robust current amplification capabilities in small outline packages.

Replacement Considerations

Cross-reference with other SOT-23 NPN Darlington transistors such as the MPSD47 or BD139 variants if pinout compatibility allows. Verify that substitute parts meet or exceed the 60 V collector-emitter voltage and 500 mA current specifications. Ensure thermal resistance characteristics align with the original design constraints.
