The CPC1786J is a single-pole, normally open, DC-only solid state relay designed for high-performance DC switching applications. It is packaged in an i4-PAC format with dimensions of 20.88 mm × 19.91 mm × 2.36 mm and features a Direct Copper Bond ceramic substrate that provides 2500 V rms input-to-output isolation and a thermal impedance from junction to case of 0.35 °C/W. The relay can handle a continuous load current of 0.65 A without a heat sink and up to 1.75 A with a 5 °C/W heat sink, while blocking up to 1000 V DC. Its maximum on-resistance is 2 Ω at 1 A load current. 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
