The CPC1779J is a single-pole, normally open, DC-only solid state relay with a 600 V blocking voltage and a continuous load current of 1.65 A without a heat sink, or 4.12 A with a 5°C/W heat sink. It features a 0.4 Ω maximum on-resistance and 2500 V rms input-to-output isolation in an ISOPLUS-264 package, measuring 26.162 mm × 19.914 mm × 5.029 mm. The device has a junction-to-case thermal impedance of 0.3 °C/W and operates from -40 °C to +85 °C ambient. 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
DC Only Single Pole i4-PAC / TUBE RoHS Compliant: Yes
