2SC5490A-TL-H

Overview

The onsemi 2SC5490A-TL-H is a discontinued NPN epitaxial planar silicon RF transistor designed for UHF to S-band low-noise amplifier applications. It operates with low voltage and current, featuring a maximum collector-to-emitter voltage of 10V and a continuous collector current of 30mA. The device offers a high cut-off frequency (fT) of up to 8GHz at VCE=5V/IC=10mA, or 3.5GHz at VCE=1V/IC=1mA. Typical noise figures are 0.9dB at 1GHz and 1.4dB at 1.5GHz. Forward transfer gain reaches 10dB at 1.5GHz under standard conditions. It utilizes an ultrasmall SSFP package measuring 1.4mm x 0.8mm x 0.6mm.

Feature Summary

• Ultrasmall slim flat-lead package design
• Halogen-free compliance

Applications

• UHF to S-band low-noise amplifiers
