Features
Silicon Stabilizer Diodes
Monolithic integrated analog circuits designed for
small power stabilizer and limitation circuits,
providing low dynamic resistance and high-quality
stabilization performance as well as low noise. In the
reverse direction, these devices show the behavior of
forward-biased silicon diodes.
The end of the ZTE device marked with the cathode ring
is to be connected: ZTE1.5 and ZTE2 to the negative
pole of the supply voltage; ZTE2.4 thru ZTE5.1 to the
positive pole of the supply voltage.
These diodes are also available in MiniMELF case with
the type designation LL1.5 ... LL 5.1.
