CPC1511 is a single-pole, normally open (1-Form-A) optically isolated Solid State Relay with integrated current limit and thermal shutdown features. Perfect for replacing electromechanical relays while enhancing the robustness of wireline-interface applications, the CPC1511 can carry loads up 450mADC/mArms.

The relay is constructed using an efficient LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high voltage dielectrically isolated technology comprises a photodiode array, switch control with active current limiting and thermal shutdown circuitry, and MOSFET switches.

CPC1511 incorporates thermal shutdown circuitry for improved survivability in harsh environments, and is designed to pass regulatory voltage surge requirements when provided with appropriate over voltage protection circuitry.

Designed specifically for environmentally demanding AC or DC applications where printed circuit board space is at a premium and additional power supplies are not available, the CPC1511 is an ideal solution.
