2N5485 Description

Short technical summary and product information.

The 2N5485 is an N-channel JFET (Junction Field-Effect Transistor) designed for RF applications. Manufactured by On Semiconductor, this transistor operates with a drain-source voltage of 15V and a drain current of 10mA. It is capable of switching at frequencies up to 400MHz with a typical noise figure of 4dB.

 

The device is housed in a through-hole TO-92-3 package (TO-226-3), making it suitable for breadboard prototyping and manual assembly. The mounting type is through-hole, and the supplier device package is TO-92-3.

 

While primarily intended for RF amplification and switching, the JFET's high input impedance and low noise characteristics make it a good choice for general-purpose low-frequency applications as well. The 2N5485 is a common part for hobbyist and professional RF circuits.
