The CPC1560 is designed with thermal shutdown circuitry specifically for harsh-environment applications and speed enhancement

Clare Inc, an IXYS company, has announced the immediate production release of the CPC1560, a fast-actuating, current limiting, normally open, 1-Form-A, optically isolated Solid State Relay (SSR) solution that replaces electromechanical devices and enhances system robustness.

The CPC1560 incorporates active current-limit and 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. The device provides 3750Vrms of input to output isolation. 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 CPC1560 is an ideal solution.

The 60V CPC1560 also features fast turn-on of loads up to 600mADC in a DC-only configuration or 300mArms in an AC/DC configuration. Fast turn-on (100usec) and turn-off (400usec) is accomplished with the use of an external charge storage capacitor that provides the necessary charge required by the internal switching MOSFETs. The CPC1560 charges this capacitor, through bootstrap diodes, from the load voltage, thereby alleviating the need for an additional power supply.

This current limiting 1-Form-A normally open SSR is for general industrial control and instrumentation switching applications as well as, peripherals, security, and medical equipment. Additional key features include linear AC/DC operation, low power consumption, clean, bounce-free switching, and low power drive requirements.

Clare OptoMOS solid state relays and high voltage circuits are prevalent throughout the industry offering semiconductor control, system isolation and board savings compared to electromechanical relays.
