Vishay VO2223B Optocouplers are optically coupled phototriacs which drive integrated power TRIACs. These optocouplers feature galvanic and electrical noise isolation and can directly drive medium AC loads with low voltage input signal. The VO2223B optocouplers offer a high blocking voltage of 600V which permits control of off-line voltages up to 230VAC and is sufficient for as much as 380VAC. Typical applications include air conditioners, microwave ovens, washing machines, and refrigerators.
