LL1.5 THRU LL2.4
Silicon Planar Stabi lizer Diodes
Monolithic integrated analog circuits in Min-
iMELF case, designed for small power stabilizer and limitation circuits, providing low dynamic
resistance and high-quality
stabilization performance as well as low noise. In the
rev ers e dir ect i on, these devices show the behavior
of forward-biased silicon diodes.
The end of the device marked with the cathode ring
is to be connected:
LL1.5 and LL2 to the negative pole of the supply voltage
LL2.4 to the positive pole of the supply voltage
These diodes are also available in DO-35 case
with the type designation ZTE1.5 … ZTE2.4.
