BCV27,215

Overview

The BCV27,215 is an NPN bipolar junction transistor manufactured by Nexperia. It features a Darlington configuration housed in a SOT-23 (TO-236AB) surface-mount package. Key electrical parameters include a collector-emitter voltage (Vceo) of 30 V and a continuous collector current (Ic) of 0.5 A. The device has a maximum power dissipation of 800 mW and operates within a temperature range of -55°C to +150°C.

Feature Summary

• High current gain capability due to integrated Darlington structure
• Low saturation voltage for efficient switching performance
• Compact SOT-23 footprint suitable for space-constrained designs

Applications

• Ballast transistors in lighting circuits
• General-purpose switching applications
• Driver stages for relays or small motors

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm pinout and electrical tolerances. Ensure the component meets RoHS compliance requirements for your target market. Confirm availability through authorized distributors as lead times may vary based on production cycles.

Selection Notes

Select this component when high current drive is required from a low input signal. The Darlington configuration provides significant amplification, reducing base drive requirements. Consider thermal management due to power dissipation limits in enclosed spaces.

Part Context

This part belongs to Nexperia's discrete bipolar transistor portfolio. It is designed for general-purpose amplification and switching tasks. The SOT-23 package allows for automated assembly and reduced board space compared to through-hole alternatives.

Replacement Considerations

Check for direct equivalents with matching Vceo, Ic, and package dimensions. Verify that alternative Darlington transistors offer comparable hFE ranges and saturation voltages to ensure circuit compatibility without redesign.
