BCV49,115

Overview

The BCV49,115 is an NPN Darlington transistor manufactured by Nexperia. It features a maximum continuous collector current of 500 mA and a collector-emitter voltage rating of 60 V. The device utilizes a UPAK (SOT-89) surface-mount package with four pins. Key electrical parameters include a minimum DC current gain (hFE) of 2000, a maximum power dissipation of 1.3 W, and a collector-emitter saturation voltage of 1 V. The component operates within a temperature range of -65°C to +150°C.

Feature Summary

• High current amplification capability provided by the integrated Darlington configuration.

Applications

• General-purpose switching applications requiring high gain.

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before finalizing procurement decisions. Confirm that the SOT-89 package dimensions and pinout align with the target PCB footprint design requirements. Ensure thermal management strategies account for the specified power dissipation limits under intended operating conditions.

Selection Notes

Select this component when a single-device solution offers higher current gain than standard bipolar junction transistors. The SOT-89 package provides a compact form factor suitable for space-constrained surface-mount designs. Evaluate the 60 V breakdown voltage against circuit supply rails to ensure adequate safety margins during operation.

Part Context

This part belongs to the BCV49 series of NPN Darlington transistors from Nexperia. The series is designed for applications demanding high sensitivity and moderate current handling in a small surface-mount footprint. The BCV49 variant specifically targets general-purpose uses where superior current amplification is required without complex multi-transistor circuits.

Replacement Considerations

BCV48,115 is a confirmed PNP equivalent within the same family. Verify polarity requirements before substitution.
