Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient infrared LED.
Features
• Blocking Voltage: 600V
• Low Input Control Current: 2mA
• 4000Vrms Input/Output Isolation
• Low Drive Power Requirements
• Greater Reliability than Electromechanical Relays
• FCC Compatible
The PLA143 can be used to replace mechanical
relays, and offers the superior reliability associated
with semiconductor devices. Because it has no
moving parts, it offers faster, bounce-free switching in
a more compact surface mount or thru-hole package.
• VDE Compatible
• No EMI/RFI Generation
• Small 6-Pin Package
