BC817W,115

Overview

The BC817W,115 is an NPN general-purpose transistor manufactured by Nexperia in a SOT323 (SC-70) surface-mounted plastic package. It supports a collector-emitter voltage of 45 V and a continuous collector current of 500 mA at 25 °C. The device offers three DC current gain selections: BC817W (100–600), BC817-16W (100–250), BC817-25W (160–400), and BC817-40W (250–600). Peak collector current reaches 1 A for single pulses up to 1 ms. Thermal resistance from junction to ambient is 625 K/W in free air.

Feature Summary

• High current capability with 500 mA continuous rating
• Three distinct current gain selection groups available
• Very small SOT323 (SC-70) surface-mount package

Applications

• General-purpose switching
• Amplification circuits

Procurement Notes

Verify the specific suffix matches the required hFE binning code. Confirm the package type is SOT323. Ensure the component is non-automotive grade as per the latest datasheet revision. Check marking codes against ordering information.

Selection Notes

Select based on required current gain range. Choose BC817W for broad gain coverage. Select BC817-16W, -25W, or -40W for tighter gain tolerances. Verify thermal management requirements for PCB mounting.

Part Context

Part of the BC817W series NPN transistors. Complements the BC807W PNP series. Available in SOT323 package. Includes variants BC817-16W, BC817-25W, and BC817-40W.

Replacement Considerations

BC807W is the PNP complement. Other BC817W series variants share the package but differ in gain ranges.
