2N4393 Description

Short technical summary and product information.

The 2N4393 from SIL is an N-Channel Junction Field-Effect Transistor (JFET) designed for various switching and signal processing applications. It utilizes the InterFET N0132S geometry, offering low noise characteristics with a typical value of 1.2 nV/√Hz. This device is also noted for its fast switching capabilities.

 

A key feature of the 2N4393 is its low cutoff voltage, specified at less than 3.0V, making it suitable for low-level power supplies. The gate leakage is typically less than 50pA at room temperatures. The transistor is available in a hermetically sealed TO-18 package, which is suitable for military applications.

 

Applications for the 2N4393 include low on-resistance analog switches, choppers, and commutators. Its specifications, such as a gate-to-source breakdown voltage of -40V and a continuous device power dissipation of 1800mW, make it a robust component for demanding designs.
