BC868,115

Overview

The BC868,115 is an NPN medium power transistor manufactured by Nexperia. It operates with a maximum collector-emitter voltage of 20 V and supports a continuous collector current of 2 A. The device is housed in a SOT-89 (SC-62) surface-mount plastic package designed for efficient thermal management. It offers high power dissipation capabilities and provides two selectable current gain options to suit various circuit requirements.

Feature Summary

• High collector current capability for robust switching and amplification
• Two distinct current gain selections available for design flexibility
• High power dissipation performance within a compact SOT-89 package

Applications

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

Procurement Notes

Verify the specific current gain bin required for your application, as the BC868 series offers multiple gain selections. Confirm that the SOT-89 package dimensions align with your PCB footprint constraints. Ensure the 20 V voltage rating meets the system's maximum operating conditions. Check for any RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a single NPN transistor must handle currents up to 2 A in a small surface-mount form factor. The SOT-89 package provides superior thermal performance compared to standard SOT-23 types. Consider the available current gain variants to optimize biasing stability. This transistor is suitable for general-purpose medium-power applications requiring reliable switching or linear operation.

Part Context

The BC868 belongs to Nexperia's family of NPN medium power transistors. It complements other discrete semiconductors used in power management and signal processing. The SOT-89 packaging allows for higher power handling than smaller packages while maintaining a low profile. This series is widely used in consumer electronics and industrial equipment where space and thermal efficiency are critical design factors.

Replacement Considerations

Direct substitutes include other NPN transistors rated for 20 V and 2 A in SOT-89 packages. Verify pinout compatibility before substitution. Alternative part numbers may offer different current gain bins or slightly varied thermal characteristics. Ensure the replacement device meets the same voltage and current specifications for safe integration.
