This device uses a silicon dioxide (SiO2) insulation barrier with a withstand voltage of 5000 VRMS and a working voltage of 1060 VRMS. Electromagnetic compatibility has been significantly enhanced to enable system-level ESD, EFT, surge, and emissions compliance.
Used in conjunction with isolated power supplies, the device protects against high voltage, and prevents noise currents from the bus from entering the local ground. The ISO1042 device is available for both basic and reinforced isolation (see Reinforced and Basic Isolation Options).
The ISO1042 device supports a wide ambient temperature range of -40 to +125°C. The device is available in the SOIC-16 (DW) package and a smaller SOIC-8 (DWV) package.
