Vishay’s VOT8026A and VOT8123A series optocouplers offer high off-state voltage of 800 V and static dv/dt of 1,000 V/µs in compact DIP-6 and SMD-6 packages. These optocouplers deliver high robustness and noise isolation for home appliances and industrial equipment. They isolate low voltage logic from 120 V_AC, 240 V_AC, and 380 V_AC lines to control resistive, inductive, or capacitive loads, including motors, solenoids, high current thyristors, or TRIACs and relays. Reducing design costs and saving board space, the devices consist of a GaAs infrared LED optically coupled to either a zero-crossing TRIAC (VOT8026A) for EMI reduction without the need for external snubber networks or random-phase TRIAC (VOT8123A) to enable phase-independent switching. The high off-state voltage enhances safety margins in one-phase applications, while still maintaining enough voltage headroom for three-phase applications.
