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.

FEATURES

• Load voltage 350 V

• Clean bounce free switching

• Low power consumption

• SMD lead available on tape and reel

• Compliant to RoHS Directive 2002/95/EC and

in accordance to WEEE 2002/96/EC

APPLICATIONS

• General telecom switching

• Security equipment

• Instrumentation

• Industrial controls

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.
