BC847CW-7-F

Overview

The BC847CW-7-F is an NPN small signal transistor manufactured by Diodes Incorporated, housed in a SOT323 surface-mount package. It features a collector-emitter breakdown voltage of 45 V and a continuous collector current rating of 100 mA. The device belongs to the 'C' gain band, providing a minimum DC current gain (hFE) of 420 at IC = 2mA and VCE = 5V. Electrical characteristics include a transition frequency of 100 MHz and a maximum power dissipation of 200 mW.

Feature Summary

• Totally lead-free and fully RoHS compliant with halogen and antimony-free green packaging
• Ideally suited for automatic insertion into manufacturing equipment
• Complementary PNP types available within the BC856W–BC858W series

Applications

• General-purpose switching circuits
• Audio frequency (AF) amplifier applications

Procurement Notes

Verify that the ordering suffix '-7-F' corresponds to the specific 3,000-unit reel packing configuration listed in the official datasheet. Confirm the marking code K1M matches the BC847CW variant. Ensure compliance requirements align with the manufacturer's definitions for lead-free and green product standards.

Selection Notes

Select this component when high DC current gain is required for low-level signal amplification. The C-band gain specification ensures a minimum hFE of 420. Verify that the 45 V collector-emitter voltage rating meets the circuit requirements and that the SOT323 package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the BC846AW–BC848CW series of NPN small signal transistors designed for general-purpose use. The series utilizes a planar epitaxial silicon design optimized for automated assembly processes. It serves as the NPN complement to the BC856W–BC858W PNP transistor family.

Replacement Considerations

Cross-reference with other manufacturers offering BC847CW equivalents in the SOT323 package. Verify that replacement parts match the 45 V VCEO rating and the Band C hFE minimum of 420 to maintain circuit performance.
