The 2SC3583-T2B is a silicon NPN epitaxial planar transistor manufactured by NEC (now Renesas Electronics). It is designed for low-noise amplifier applications in VHF and UHF bands.

Applications:

• Low-noise amplifiers (LNAs)
• VHF/UHF receivers
• RF front-end circuits
• Wireless communication systems
• Satellite receivers

Features:

• Low noise figure
• High gain
• High cutoff frequency
• Small signal amplification
• Silicon NPN Epitaxial Planar Type

Benefits:

• Enhances signal sensitivity in weak signal environments.
• Improves overall system performance in wireless communication applications.
• Reduces signal distortion and unwanted noise in sensitive receiver circuits.
• Allows for compact and efficient circuit designs due to its high gain and low noise characteristics.

Additional Details:

The 2SC3583-T2B comes in a small surface-mount package (e.g., SOT-23 or similar). Key electrical characteristics include collector-emitter voltage (VCEO), collector current (IC), power dissipation (PC), noise figure (NF), and transition frequency (fT). Consult the Renesas Electronics datasheet for precise specifications, S-parameters, and recommended biasing conditions. Proper impedance matching is crucial for optimal low-noise performance. The "T2B" suffix typically indicates a specific tape and reel packaging option or a particular gain ranking within the production lot.
