2SC4093-T1-A

Overview

The 2SC4093-T1-A is an NPN silicon epitaxial RF transistor manufactured by Renesas Electronics, originally designed by NEC. It is a single-element device intended for ultra-high frequency band applications, specifically low-noise amplification in VHF, UHF, and CATV bands. The component utilizes a 4-pin minimold surface-mount package (R-PDSO-G4). Key electrical specifications include a maximum collector current of 0.1 A, a collector-emitter voltage rating of 12 V, and a transition frequency of 7000 MHz. It exhibits a typical noise figure of 1.1 dB at 1 GHz with a collector current of 7 mA.

Feature Summary

• Designed for high-frequency low-noise amplification in VHF, UHF, and CATV bands
• Features large dynamic range and good current characteristics
• Utilizes a 4-pin minimold package to enable high-isolation gain

Applications

• Low noise amplifier circuits for VHF bands
• Low noise amplifier circuits for UHF bands
• CATV band signal processing

Procurement Notes

Verify the manufacturer status carefully, as documentation indicates this specific part number may be obsolete or end-of-life with Renesas Electronics. Confirm availability through authorized distributors or secondary markets. Ensure the sourcing channel provides valid traceability for the NEC/Renesas lineage. Check for RoHS compliance status, as original datasheets indicate non-compliance.

Selection Notes

Select this component when designing for VHF, UHF, or CATV low-noise amplification requiring a 4-pin SMD form factor. Verify that the 12 V collector-emitter voltage and 0.1 A current limits meet circuit requirements. Consider the 1.1 dB noise figure specification at 1 GHz for sensitive front-end stages. Ensure the design accommodates the specific thermal and mounting constraints of the minimold package.

Part Context

This component belongs to the 2SC4093 series of NPN silicon RF transistors. The base model was originally developed by NEC (Nippon Electric Company) and later transferred to Renesas Electronics following corporate restructuring. Variants such as 2SC4093-T1-RBG share similar functional characteristics but may differ in packaging suffixes or manufacturing origin details.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineering teams should consult official Renesas or NEC replacement notices for obsolescence management.
