Pin Configuration
TS120L is a 350V, 120mA, 35
1-Form-A relay with
an optocoupler in a single package. It is a more cost
effective solution for telecom applications that do not
require a high sensitivity relay.

Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at these or
any other conditions beyond those indicated in the opera-
tional sections of this data sheet is not implied. Exposure
of the device to the absolute maximum ratings for an
extended period may degrade the device and effect its
reliability.
