Description
The PLA170 is a 1-Form-A Solid State Relay which uses optically coupled MOSFET technology to provide enhanced input-to-output isolation of 3750Vrms. The efficient MOSFET switches and photovoltaic die use Clare’s patented OptoMOS® architecture. The optically-coupled output is controlled by a GaAIAs infrared LED. The PLA170 is designed to replace electromechanical relays and offers the superior reliability associated with Solid State devices. This device provides bounce-free switching in a more compact surface mount or through hole package.
Features
• 100% Solid State • Small 6 Pin Package • Low Drive Power Requirements (TTL/CMOS Compatible) • Arc-Free With No Snubbing Circuits • 3750Vrms Input/Output Isolation • No EMI/RFI Generation • Machine Insertable, Wave Solderable • 800V blocking
Approvals
• UL Recognized File: E76270 • CSA Certified File: LR 43639-10 • Certified to: • EN 60950 • EN 41003
