2N5912C
MONOLITHIC DUAL
N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix & National 2N5912C
The 2N5912C are monolithic dual JFETS. The
monolithic dual chip design reduces parasitics and
gives better performance at very high frequencies while
ensuring extremely tight matching. These devices are
an excellent choice for use as wideband differential
amplifiers in demanding test and measurement
applications. The 2N5912C is a direct replacement for
discontinued Siliconix and National 2N5912C.
The hermetically sealed TO-71 is well suited for military
applications.
(See Packaging Information).
