New Silicons and Electronics

Vishay broadened its optoelectronics portfolio with the release of two new series of optocouplers with phototriac output in compact DIP-6 and SMD-6 packages. Offering high off-state voltage of 800 V and static dV/dt of 1000 V/μs, the Vishay Semiconductors VOT8026A and VOT8123A deliver high robustness and noise isolation for home appliances and industrial equipment. The optocouplers announced today isolate low voltage logic from 120 VAC, 240 VAC, and 380 VAC 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 a random-phase TRIAC (VOT8123A) to enable phase-independent switching. The high off-state voltage of the VOT8026A and VOT8123A enhances safety margins in one-phase applications, wh...
