BCV27-TP

Overview

The BCV27-TP is an NPN Darlington transistor manufactured by Micro Commercial Components (MCC). It features a collector-emitter voltage of 40 V and a continuous collector current of 1 A. The device offers a high DC current gain ranging from 500 to 3000 at a collector current of 10 mA. Power dissipation is rated at 625 mW in the SOT-89-3 package. Operating temperatures range from -55°C to +150°C, with a maximum junction temperature of 150°C.

Feature Summary

• High DC current gain for sensitive signal amplification
• NPN Darlington configuration for low drive requirements
• SOT-89-3 surface mount package for compact designs

Applications

• General-purpose switching applications
• Low-power amplifier circuits
• Driver stages for relays or LEDs

Procurement Notes

Verify the specific datasheet version for the BCV27-TP to confirm exact electrical characteristics and thermal resistance values. Ensure that the SOT-89-3 footprint matches the target PCB layout. Confirm RoHS compliance status through official MCC documentation prior to finalizing component selection for production.

Selection Notes

Select this component when high current gain is required with minimal base drive current. The SOT-89-3 package provides a balance between power handling and size. Consider thermal management requirements given the 625 mW dissipation rating in free air conditions.

Part Context

The BCV27-TP belongs to the Micro Commercial Components (MCC) discrete semiconductor portfolio. MCC specializes in general-purpose diodes, transistors, and protection devices. This part represents their standard NPN Darlington transistor offering designed for cost-effective consumer and industrial electronics.

Replacement Considerations

Consult official MCC substitution guides for verified equivalents. Common industry alternatives may include BD139 or similar NPN Darlington pairs, but pinout and package compatibility must be verified.
