1 Form B Solid State Relay
LH1501BAB, LH1501BABTR, LH1501BT
Vishay Semiconductors
DESCRIPTION
The LH1501 relays are SPST normally closed switches
(1 form B) that can replace electromechanical relays in many
applications. The relays are constructed 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
configured for AC/DC or DC only operation.

Notes
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.
