Dual 1 Form B Solid State Relay
DESCRIPTION
The LH1523 dual 1 form B relays are SPST normally closed
switches 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.
FEATURES
• Dual channel (LH1511)
• Isolation test voltage 3750 VRMS
• Typical RON 10
• Load voltage 200 V
• Load current 200 mA
• High surge capability
• 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
- On/off hook control
- Ring delay
- Dial pulse
- Ground start
- Ground fault protection
• 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) Breakdown occurs between the output pins external to the package.
(2) Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through
hole devices (DIP).
Note
• 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.
