Dual 1 Form A Solid-State Relay (Normally Open)
DESCRIPTION
The VOR2121 is a 250 V dual channel normally open
optically isolated solid-state relay (SPST - 1 form A). Based
on hybrid architecture which allows fast switching times
with a wide operating ambient temperature range. A high
efficient GaAlAs IRED enables low forward current on the
input side. On the output side high performance MOSFET
switches provide a low R
ON
and can switch both DC and AC
signals.
FEATURES

Note
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.
Note
Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering
evaluations. Typical values are for information only and are not part of the testing requirements.
