Description
The LH1510 is a SPST normally open switch (1 Form
A) that can replace electromechanical relays in many
applications. The relay is constructed using a GaAlAs
LED for actuation control and an integrated monolithic
die for the switch output. The die, fabricated in a high-
voltage dielectrically isolated technology, is com-
prised of a photodiode array, switch control circuity,
and MOSFET switches. In addition, the relay employs
current-limiting circuity enabling it to pass FCC
68.302 and other regulatory voltage surge require-
ments when overvoltage protection is provided. The
LH1510 is the only relay in the family that provides
current limiting for unidirectional dc applications.

Absolute Maximum Ratings, T
amb
= 25 C
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 time can adversely affect reliability.

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.
