Overview
The KSC2756YMTF is an NPN epitaxial silicon transistor manufactured by onsemi, originally documented under Fairchild Semiconductor. It operates with a collector-base voltage of 30 V and a collector-emitter voltage of 20 V. The device supports a maximum collector current of 30 mA and dissipates up to 150 mW at 25°C ambient temperature. Key electrical characteristics include a DC current gain (hFE) ranging from 60 to 240 depending on the classification grade, and a transition frequency (fT) between 500 MHz and 850 MHz. At 200 MHz RF input and 58 MHz IF output, it provides a typical conversion gain of 23 dB with a noise figure of 6.5 dB.
Feature Summary
- Designed for mixer applications in VHF TV tuners
- High conversion gain performance at specified frequencies
- Low noise figure suitable for sensitive signal processing
Applications
- VHF TV tuner mixers
- RF signal processing circuits
- Low-noise amplifier stages
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm lot traceability and datasheet revision status prior to integration. Ensure storage conditions remain within the specified -55°C to +150°C range to maintain junction integrity. Check for RoHS compliance documentation if required by regional regulations.
Selection Notes
Select this component when designing VHF tuner circuits requiring high conversion gain and low noise characteristics. Ensure the operating collector current remains within the 30 mA limit to prevent exceeding power dissipation ratings. Verify that the required hFE grade aligns with the specific application's gain requirements, as classifications vary from 60 to 240.
Part Context
This part belongs to the KSC2756 series of NPN epitaxial silicon transistors. Originally produced by Fairchild Semiconductor, the product line is now managed by onsemi. The device utilizes a SOT-23 surface-mount package, designed for compact electronic assemblies requiring small form factors and reliable RF performance in consumer television applications.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the SOT-23 package and meet the 20 V VCEO and 30 mA IC specifications. Verify equivalent fT and conversion gain parameters to maintain circuit performance.
