Features
• Small 4 Pin SOP Package
• Low Drive Power Requirements (TTL/CMOS
Compatible)
• No Moving Parts
• High Reliability
• Arc-Free With No Snubbing Circuits
• 1500Vrms Input/Output Isolation
• 0.4mm distance through insulation (supplementary
isolation requirement of EN60950)
• No EMI/RFI Generation
• Machine Insertable, Wave Solderable
• Tape & Reel Version Available
Description
The CPC1231N is a miniature 1-Form-B solid state
relay which uses optically coupled MOSFET technology to provide 1500Vrms of input to output isolation and is certifide for Supplemented Isolation in
accordance with EN60950. The efficient MOSFET
switches and photovoltaic die use Clare’s patented
OptoMOS® architecture. The optically-coupled input
is controlled by a highly efficient GaAIAs infrared
LED. The CPC1231N offers board space savings
of at least 20% versus competitive 4 Pin SOP solid
state relay.
