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
• Isolation test voltage 3750 VRMS
• Typical RON 20
• 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.
(1) Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through
hole devices (DIP).
