Overview
The KSC2757OMTF is an NPN bipolar RF transistor manufactured by Fairchild Semiconductor, designed for very high frequency applications. It features a collector-emitter breakdown voltage of 15V and a transition frequency of 1.1GHz. The device supports a maximum collector current of 50mA with a power dissipation rating of 150mW. Packaged in the SOT-23 (TO-236-3) surface-mount format, it is supplied in tape and reel configuration for automated assembly.
Feature Summary
- Optimized for mixer and oscillator circuits within VHF tuner architectures
- Engineered for high-frequency signal processing at 1.1GHz transition rates
- Utilizes compact SOT-23 surface-mount packaging for space-constrained designs
Applications
- VHF tuner mixer stages
- RF oscillator circuits
- Very high frequency signal amplification
Procurement Notes
Verify the manufacturer part number against official Fairchild or onsemi documentation to ensure authenticity. Confirm that the specific suffix 'OMTF' corresponds to the required tape and reel packaging variant. Cross-reference the RoHS status and component marking codes with the latest datasheet revisions to guarantee compliance with current environmental standards and supply chain requirements.
Selection Notes
Select this component when designing circuits requiring an NPN RF transistor with a 15V breakdown voltage and 1.1GHz performance. Ensure the application operates within the 150mW power dissipation limit. The SOT-23 package requires appropriate PCB footprint design for thermal management and signal integrity at very high frequencies compared to lower-frequency general-purpose transistors.
Part Context
This device belongs to the family of RF small-signal transistors intended for communication hardware. It serves as a critical active element in tuning and frequency conversion modules. The component bridges discrete semiconductor technology with integrated circuit functionality in analog radio frequency paths.
Replacement Considerations
Consult official substitution guides for equivalent NPN RF transistors with matching 15V ratings and 1.1GHz transition frequencies. Verify pinout compatibility and thermal characteristics before integrating alternative components into existing VHF tuner layouts.
