CPC1978J i4-PAC™ Power Relay Blocking Voltage Load Current On-resistance RθJC CPC1978J 800 2.5 2.3 0.35 Description Clare and IXYS have combined to bring OptoMOS technology, reliability and compact size to a new family of high power solid state relays. The CPC1978J, a 1-Form-A solid state relay, is part of this new family. The CPC1978J employs optically coupled MOSFET technology to provide 2500Vrms of input to output isolation. The efficient MOSFET switches and photovoltaic die use Clare’s patented OptoMOS architecture while the input is controlled by a highly efficient GaAlAs infrared LED. The combination of low on resistance and high load current handling capability makes the relay suitable for a variety of high performance switching applications. Units VP Arms Ω °C/W Features • Compact i4-PAC™ Power Package • Low Thermal Resistance • Heat Sink Option • Handle Load Currents Up to 2.5Arms (free air) • High Reliability • No Moving Parts • Low Drive Power Requirements (TTL/CMOS Compatible) • Arc-Free With No Snubbing Circuits • 2500Vrms Input/Output Isolation • No EMI/RFI Generation • Machine Insertable, Wave Solderable Applications • Industrial Controls • Motor Control • Robotics • Medical Equipment—Patient/Equipment Isolation • Instrumentation • Multiplexers • Data Acquisition • Electronic Switching • I/O Subsystems • Meters (Watt-Hour, Water, Gas) • Transportation Equipment • Aerospace/Defense The unique i4-PAC™ package pioneered by IXYS allows solid state relays to achieve the highest current and power ratings. This package features an IXYS unique process where the silicon chips are soft soldered onto the Direct Copper bond (DCB) substrate instead of the usual copper leadframe. The DCB ceramic, the same substrate used in high power modules, not only provides 2500Vrms isolation, but also very low thermal resistance.
