2SC5226A-4-TL-E

Overview

The onsemi 2SC5226A-4-TL-E is a Pb-free NPN single RF transistor designed for high-frequency applications. It operates with a collector-to-emitter voltage of 10 V and supports a maximum collector current of 70 mA, dissipating up to 150 mW of power. The device features a typical gain-bandwidth product (fT) of 7 GHz at 20 mA. At 1 GHz, it provides a forward transfer gain magnitude squared of 12 dB and a noise figure as low as 1.0 dB. Packaged in the SC-70 / MCP3 surface-mount format, it is suitable for compact RF circuit designs.

Feature Summary

• High cut-off frequency enabling operation at microwave frequencies
• Low-noise performance optimized for sensitive signal reception
• High forward transfer gain for efficient amplification

Applications

• RF amplifier stages in communication systems
