J109 Description

Short technical summary and product information.

The ON Semiconductor J109 is an N-Channel Junction Field-Effect Transistor (JFET) designed for digital switching applications requiring very low on-resistance. It operates with a drain-gate voltage of up to 25V and a gate-source voltage of -25V.

 

This JFET offers a maximum power dissipation of 625 mW at 25°C and has a junction-to-ambient thermal resistance of 200 °C/W. The zero-gate voltage drain current (IDSS) is 40 mA at 15V, and the drain-source on-resistance (RDS(on)) is a maximum of 12 Ohms under specific test conditions.

 

The J109 is housed in a TO-92-3 package, suitable for through-hole mounting. Its operating temperature range is from -55°C to 150°C (TJ). Key electrical characteristics include a gate-source cut-off voltage (VGS(off)) between -2.0V and -6.0V, and various capacitance values such as Cdg(on) of 85 pF and Csg(off) of 15 pF.

 

This device is sourced from Process 58 and is Pb-Free. It is suitable for applications where low on-resistance is a critical design parameter.
