The CPC1777J is a single-pole normally open DC-only solid state relay using OptoMOS technology for 2500V rms input-to-output isolation. It is housed in an i4-PAC package with dimensions of 20.879 × 19.914 × 5.029 mm and features a Direct Copper Bond ceramic substrate for low thermal impedance. The relay supports a maximum DC load current of 4.6A with a 5°C/W heat sink and 1.5A without, with a maximum on-resistance of 0.5 Ω and a 600V blocking voltage. Thermal impedance from junction to case is 0.35°C/W. It 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
