Dual 1 Form A Solid-State Relay (Normally Open)
DESCRIPTION
The LH1505 contains two normally open switches (dual
1 Form A) that can be used as two independent SPST relays
or as one DPST relay. It can replace electromechanical
relays in many applications. They are constructed using a
GaAIAs LED for actuation control and MOSFET switches for
the output. In addition, the LH1505 SSRs employ
current-limiting circuitry when overvoltage protection is
provided.
FEATURES
• Isolation test voltage 5300 VRMS
• Current limit protection
• Typical RON 12 Ω
• Load voltage 250 V
• Load current 120 mA
• Clean bounce free switching
• Low power consumption
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
• General telecom switching
• Security equipment
• Instrumentation
• Industrial controls
• Automatic test equipment
AGENCY APPROVALS
• UL1577, file no. E52744

Note
• 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
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
