Idss Choices
One of the most common questions is what Idss sub-group to choose. All JFETs are grade B/BL (6-12mA). You can now choose from an Idss sub-range. If you are building any of the First Watt products, Nelson has provided a summary. Learn more about how to choose the right Idss for your project.

Specifications
- All parts are guaranteed to be new and authentic (Linear Systems are new, Toshiba are new-old-stock)
- Guaranteed matched to within ±0.2mA. Tested at 10V / 22'C. For more information visit the JFET matching information page.
- Manufacturer specifications: LSK170 | LSJ74 | 2SK170 | 2SJ74
- Note that any letters or numbers printed on Linear Systems JFETs do not refer to grade, they are batch identification. All grades have identical physical housing. You cannot tell the grade by looking at the JFET itself. The only way to know the grade is by testing for Idss.
