The CPC1979J is a single-pole, normally open solid state relay designed for AC and DC load switching, using optically coupled MOSFET technology with 2500V rms input-to-output isolation. It is packaged in an ISOPLUS-264 case measuring 26.162 mm x 19.964 mm x 5.029 mm, with a Direct Copper Bond ceramic substrate that provides low thermal impedance. The relay handles up to 3.5A rms continuous load current with a 5°C/W heat sink and has a maximum on-resistance of 0.75Ω. Its junction-to-case thermal impedance is 0.3 °C/W, and it operates from -40°C to +85°C. The device is UL 508 recognized and complies with EN IEC 62368-1.
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
