BC868-QX

Overview

The BC868-QX is a 20 V, 2 A NPN medium power transistor manufactured by Nexperia. It utilizes the SOT89 (SC-62) surface-mount plastic package. Key electrical ratings include a maximum collector-emitter voltage of 20 V and a continuous collector current of 2 A. The device features high power dissipation capability and offers two distinct current gain selections to accommodate various circuit requirements.

Feature Summary

• High collector current capability for robust switching performance
• Two selectable current gain options for design flexibility
• High power dissipation capacity within a compact SMD form factor

Applications

• Linear voltage regulators
• MOSFET drivers
• Low-side switches
• Power management circuits
• Amplifiers

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm exact binning or packaging variations. Confirm that the component meets AEC-Q101 automotive qualification standards if required for the target application. Ensure the ordering part number matches the desired current gain selection variant before finalizing procurement.

Selection Notes

Select this component when a medium-power NPN transistor with 2 A current handling is required in an SOT89 package. Consider the available current gain bins to match amplifier or switch specifications. Evaluate thermal management needs due to the moderate power dissipation capabilities inherent to the SOT89 plastic package structure.

Part Context

This part belongs to Nexperia's BC868 series of medium power transistors. It serves as the NPN counterpart to the BC869 PNP device. The series is designed for general-purpose power applications requiring higher current than standard small-signal transistors but housed in a compact surface-mount footprint suitable for automated assembly.

Replacement Considerations

Direct substitutes include other 20 V, 2 A NPN transistors in the SOT89 package. Verify pinout compatibility and thermal resistance characteristics. Check if alternative manufacturers offer equivalent current gain bins and power dissipation ratings for seamless integration.
