KSC1675CYBU

Single Bipolar Transistors Overview

The KSC1675CYBU is an NPN epitaxial silicon RF bipolar transistor manufactured by onsemi, formerly Fairchild Semiconductor. It operates at a maximum frequency of 300 MHz with a collector-emitter voltage (VCEO) of 30 V and an emitter-base voltage (VEBO) of 5 V. The device supports a continuous collector current of 50 mA and features a minimum DC current gain (hFE) of 120. Power dissipation is rated at 250 mW in a TO-92 through-hole package. Operating temperatures range from -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the manufacturer designation carefully as onsemi acquired Fairchild Semiconductor's discrete product line. Confirm that the specific suffix matches the required electrical characteristics and packaging style. Check availability status as distribution channels may vary due to corporate restructuring or lifecycle changes. Ensure compliance with RoHS directives if required for the target assembly process.

Single Bipolar Transistors Selection Notes

Select this component when an NPN RF transistor with moderate power handling and high gain is required. The TO-92 package suits through-hole prototyping and low-volume production. Compare the 300 MHz cutoff frequency against circuit requirements to ensure adequate performance margins. Consider thermal management capabilities given the 250 mW dissipation limit in standard packages.

Single Bipolar Transistors Part Context
