Overview
The BCV27TC is an NPN silicon planar Darlington transistor manufactured by Diodes Incorporated. It features a collector-emitter breakdown voltage of 30 V and a continuous collector current of 500 mA. The device operates in a surface-mount SOT-23-3 package with a maximum power dissipation of 330 mW. Key electrical characteristics include a transition frequency of 170 MHz and a DC current gain (hFE) of 1V at 20,000 when tested at 100 mA with a collector-emitter voltage of 5 V.
Feature Summary
- High DC current gain capability for efficient signal amplification
- Fast switching performance suitable for high-frequency applications
- Compact surface-mount packaging for automated assembly
Applications
- General-purpose switching circuits
- Low-power amplifier stages
- Driver circuits for loads requiring moderate current handling
Procurement Notes
Verify component status carefully as the BCV27TC is listed as obsolete and no longer manufactured by Diodes Incorporated. Confirm availability through authorized distributors or check for valid substitute part numbers before finalizing procurement plans to ensure supply chain continuity.
Selection Notes
Select this component only if legacy compatibility is required or if specific historical design parameters match the application needs. Evaluate alternative active components that offer similar electrical specifications and package dimensions to mitigate risks associated with end-of-life products.
Part Context
This component belongs to the single bipolar transistor category from Diodes Incorporated. It utilizes NPN Darlington technology within a standard SOT-23-3 footprint, designed for compact electronic designs requiring reliable switching and amplification functions in consumer and industrial electronics.
Replacement Considerations
The MMBTA14-7-F is identified as a similar available substitute part number for the obsolete BCV27TC. Verify pinout compatibility and electrical parameter alignment before implementation.
