HFA3128B Description

Short technical summary and product information.

The HFA3128B is a 5 PNP RF small signal transistor manufactured by Intersil. It is designed for high-frequency amplification and switching applications. Key electrical specifications include a collector-emitter voltage (Vceo) of 15V, a collector current (Ic) of 65mA, and a power dissipation of 150mW. The transistor achieves a transition frequency (fT) of 5.5GHz and a typical noise figure of 3.5dB at 1GHz. The minimum DC current gain (hFE) is 20 at 10mA and 2V.

 

The device is housed in a 16-SOIC surface mount package with a width of 3.90mm. It supports a junction operating temperature up to 150°C. The 5 PNP configuration integrates five PNP transistors in a single package, suitable for RF signal processing and driver stages. The surface mount design enables compact PCB layouts and automated assembly.
