BC817-25W RFG

Overview

The BC817-25W RFG is an NPN general-purpose bipolar junction transistor manufactured by Taiwan Semiconductor Corporation. It utilizes silicon epitaxial planar technology and is housed in a surface-mount SOT-323 (SC-70) plastic package. The device supports a maximum collector current of 500 mA and a collector-emitter voltage of 45 V. It features a DC current gain range of 160 to 400 at 100 mA. Key electrical parameters include a transition frequency of 100 MHz, a collector-base voltage of 50 V, and an emitter-base voltage of 5 V. Power dissipation is rated at 200 mW, with an operating temperature range from -55°C to +150°C.

Feature Summary

High current capability for general-purpose switching applications
Three distinct current gain selections available within the series
Complementary PNP counterpart provided by the BC807 series

Applications

General-purpose switching circuits
Amplifier stages
Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix 'RFG' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure the component matches the SOT-323 footprint requirements. Cross-reference the part number with authorized distributors to confirm authenticity and availability of the correct revision.

Selection Notes

Select this component when a small surface-mount NPN transistor with moderate current handling is required. The BC817-25 variant offers a specific gain band suitable for consistent amplification. Consider the complementary BC807-25 if a PNP solution is needed for push-pull configurations.

Part Context

This component belongs to the BC817 family of NPN general-purpose transistors. The family includes variants with different gain ranges, such as BC817-16 and BC817-40. These devices are widely used in consumer electronics and industrial control systems due to their reliability and compact SOT-23 or SOT-323 form factors.
