General Semiconductor ZTE1.5, ZTE2, ZTE2.4 Datasheet

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 to the
positive pole of the supply voltage

• These diodes are also available in MiniMELF

case with the type designation LL1.5 … LL 2.4.
