JFET Component Data
Data for JFETs or Junction Field Effect Transistors including pinout and package outlines, operational parameters and component descriptions, applications, cost and distributor sources.
Here I've detailed the essential data for a variety of Junction Field Effect Transistors or JFETs: everything from their vital parameters including their maximum voltages and currents as well as factors including RDS ON, etc.
There is also information about distributors that hold the components and the costing, etc.
