Description

CPC1561B is a single-pole, normally open (1-Form-A)

optically isolated Solid State Relay with integrated

current limit and thermal shutdown features. The

current limit remains flat over the operating

temperature range. Perfect for replacing

electromechanical relays while enhancing the

robustness of applications. The CPC1561B can switch

The relay is constructed using an efficient LED and a

photodiode array die for actuation control and an

integrated monolithic die for the switch output. The

protected switch die, fabricated in a high voltage

dielectrically isolated technology, comprises switch

control, active current limiting, and thermal shutdown

circuitry with the MOSFET switches.

CPC1561B 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 the CPC1561B is an ideal

solution.
