Bare Die Product Detail: J109

N-Channel Switch / Chopper:
Low noise Single N-Channel JFET switch. The J109 N-channel JFET is optimised for low noise high performance switching. The part is particularly suitable for use in low noise audio amplifiers.

Suited for switching & chopper applications this device features low on resistance with fast turn-on time. The device directly replaces Interfet, Intersil, Motorola, National / Fairchild, Philips, Vishay / Siliconix J109 or SST109 & Toshiba 2SJ109.

Features:

Low On Resistance
Low insertion loss
Low noise

Applications:

Analog Switches
Commutators
Choppers
