DESCRIPTION
The J105/106/107 are high-performance JFET analog
switches designed to offer low on-resistance and fast
switching. rDS(on) <3 W is guaranteed for the J105 making this
device the lowest of any commercially available JFET.
The low cost TO-226AA (TO-92) plastic package is available
in a wide range of tape-and-reel options (see Packaging
Information). For similar products in TO-206AC (TO-52)
packaging, see the U290/291 data sheet.
