Vishay Semiconductor's NZC power phototriac with dV/dt of 500 V/μs complements the existing broad phototriac offering, which includes devices with the highest dV/dt rating in the industry at 10 kV/μs. The VO2223/VO2223A and the VO3526 are designed for applications where load current is limited to 1 ARMS. These new devices eliminate the need for an external power TRIAC, saving on board space and costs.
