Description
The LH1511 relays are SPST normally closed
switches (1 Form B) that can replace electromechan-
ical relays in many applications. The relays are con-
structed as a multi-chip hybrid device. Actuation
control is via an Infrared LED. The output switch is a
combination of a photodiode array with MOSFET
switches and control circuity. The relays can be con-
figured for AC/DC or DC only operation.
Order Information
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.
