BCV47 TR PBFREE

Overview

The BCV47 TR PBFREE is a surface-mount NPN Darlington transistor manufactured by Central Semiconductor Corp. It utilizes the TO-236AB (SOT-23) package and is designed for low-power switching and amplification applications. The device features a collector-emitter voltage rating of 60 V and a continuous collector current capacity of 500 mA. Key electrical characteristics include a transition frequency of 220 MHz, a maximum power dissipation of 250 mW, and a DC current gain minimum of 10,000 at specified test conditions. The component supports an operating junction temperature up to 150°C.

Feature Summary

• High current gain capability suitable for sensitive signal amplification
• Compact surface-mount form factor for space-constrained designs
• Robust thermal performance with high junction temperature tolerance

Applications

• Low-noise audio pre-amplifier stages
• General-purpose switching circuits in consumer electronics
• Driver stages for relay or LED control systems

Procurement Notes

Verify the specific manufacturer source, as the provided reference data identifies the BCV47 primarily under Nexperia branding. Confirm that the Central Semiconductor variant matches the required pinout and electrical tolerances. Ensure the ordering suffix corresponds to the correct tape-and-reel packaging configuration for automated assembly processes.

Selection Notes

Select this component when a high-gain NPN Darlington configuration is required in a small SOT-23 footprint. It is appropriate for applications demanding moderate current handling with minimal base drive current. Consider the 250 mW power limit and thermal management requirements during PCB layout to ensure reliable operation within the specified temperature range.

Part Context

This part belongs to the family of small-signal NPN Darlington transistors. Darlington configurations provide significantly higher current gain than single-transistor alternatives, making them ideal for driving loads with very low input currents. The TO-236AB package is standard for low-power surface-mount applications across various industrial and consumer sectors.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct replacements such as the BCV47,235 from Nexperia, ensuring pinout alignment and electrical parameter equivalence before implementation.
