CPC1560 Normally Open Solid State Relays

IXYS Integrated Circuits CPC1560 Normally Open Solid State Relays with Integrated Current Limit are 1-Form-A (single pole, normally open) optically isolated MOSFET switches that provide fast turn-on of loads up to 600mA_DC in a DC-Only configuration and 300mA_RMS in an AC/DC configuration. IXYS Integrated Circuits CPC1560 Solid State Relays also offer active current-limit circuitry and 3750V_RMS of I/O isolation. The series accomplishes fast turn-on with the use of an external charge storage capacitor that provides the necessary charge required by the internal switching MOSFETs. The device charges this capacitor, through bootstrap diodes, from the load voltage, alleviating the need for an additional power supply.
