• Compact SOT-323 leadless surface-mount package design

Applications

• General-purpose switching circuits
• Audio frequency amplification stages
• Driver applications for low-power loads

Procurement Notes

Verify the specific suffix 'RFG' against the manufacturer's official datasheet to confirm packaging type and compliance status. Ensure the ordering part number matches the exact electrical grade required for the target application circuit design specifications.

Selection Notes

Select this component when a small footprint is required alongside standard NPN switching capabilities. Compare the 200 mW power dissipation limit against thermal requirements. Verify compatibility with the complementary PNP device if push-pull configurations are necessary for the specific circuit topology.

Part Context

This part belongs to the BC817 family of NPN general-purpose transistors. It serves as the high-gain variant within the series, complementing the BC807 PNP counterpart. The device is designed for use in consumer electronics and industrial control systems requiring reliable small-signal handling.

Replacement Considerations

Direct substitutes include BC817-16 from other manufacturers such as Nexperia or Diodes Incorporated. Verify pinout compatibility and ensure equivalent hFE grades match the original design requirements before substitution.
