The CPC1788J is a single-pole, normally open DC-only solid state relay using optically coupled MOSFET technology for high-power switching applications. It is packaged in an ISOPLUS-264 case, measuring 26.162 mm in length, 19.914 mm in width, and 18.034 mm in height. It supports a maximum DC load current of 2.45 A with a 5°C/W heat sink and 1 A without a heat sink, with a blocking voltage of 1000 V and a maximum on-resistance of 1.25 Ω. The device offers 2500 V rms input-to-output isolation and a junction-to-case thermal impedance of 0.3 °C/W. It is rated for operation from -40 °C to +85 °C ambient temperature and meets UL 508 and EN IEC 62368-1 safety standards.
Optically isolated MOSFET-based solid state power relays in i4-PAC and ISOPLUS-264 packages feature Direct Copper Bond ceramic substrates that enable substantially lower junction-to-case thermal impedance. They are available in AC/DC and DC-only versions. For power applications requiring a heat sink for superior thermal performance, the i4-PAC and ISOPLUS-264 power relays are an ideal solution. Current Loads up to 15 Arms @ Tc=25°C Dc Loads up to 32 A at 25°C 2.5 kVrms Input-to-Output Isolation Load Voltage ratings up to 1 kV Low On-resistance down to 50 mΩ Low input control current Low thermal junction to case impedances: 0.35°C/W - i4-PAC 0.30°C/W - ISOPLUS-264
