SST113
N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix SST113
This n-channel JFET is optimised for low noise high
performance switching. The part is particularly suitable
for use in low noise audio amplifiers. The SOT-23
package is well suited for cost sensitive applications
and mass production.
(See Packaging Information).
