2SC48050QL

Overview

The Panasonic 2SC48050QL is a silicon NPN epitaxial planar transistor designed for low-noise amplification in the 2 GHz band. It features an S-Mini (SC-70) package with dimensions of 1.3 mm by 2.1 mm, facilitating equipment downsizing and automated insertion via tape or magazine packing. The component operates with a maximum collector-emitter voltage of 10 V and a collector current limit of 65 mA. Key electrical characteristics include a transition frequency ranging from 7.0 to 8.5 GHz at 1.5 GHz, a noise figure between 2.2 and 3.0 dB, and a forward current transfer ratio of 50 to 300 depending on the specific rank classification.

Feature Summary

• Engineered for high-frequency performance with a transition frequency reaching up to 8.5 GHz.
• Optimized for low-noise applications with a guaranteed noise figure as low as 2.2 dB.
• Utilizes a compact S-Mini package to support automatic insertion and reduced footprint.

Applications

• Low-noise amplification circuits operating in the 2 GHz band
• Communications equipment requiring high-frequency signal processing
• Measuring instruments utilizing RF signal paths

Procurement Notes

Verify the exact lifecycle status through official Panasonic channels before procurement, as the datasheet indicates potential maintenance or discontinuation phases. Confirm that the 'QL' suffix aligns with the standard 'Q' rank specifications documented in the official product standards. Ensure compliance with RoHS directives applicable to your region and validate that the SC-70 package dimensions match your PCB layout requirements.

Selection Notes

Select this component when designing circuits specifically targeting the 2 GHz frequency range where low noise figures are critical. Consider the 65 mA collector current limit and 150 mW power dissipation capability during thermal management planning. Evaluate the available hFE ranks (Q, R, S) to ensure the gain characteristics meet the specific amplifier design requirements.

Part Context

The 2SC4805 series represents a line of silicon NPN transistors developed by Panasonic Semiconductor for UHF and 2 GHz band applications. This specific model utilizes the S-Mini package variant, which distinguishes it from larger TO-92 or other surface-mount packages within the broader transistor family. It serves as a specialized solution for high-frequency signal integrity in compact electronic designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the verified source material. Consult official Panasonic documentation for cross-reference data or equivalent components if availability is constrained.
