Vishay Semiconductors VOx619A-3X0xT Phototransistor Output Optocouplers are designed for high-performance signal isolation in industrial and consumer applications. These devices feature a high current transfer ratio (CTR) across a wide range of input currents, ensuring reliable signal transmission even at low input levels. Housed in compact DIP and SMD packages, the Vishay Semiconductors VOx619A-3X0xT offer excellent insulation voltage ratings up to 5000VRMS and are compliant with safety standards such as UL, VDE, and CQC. The VOx619A-3X0xT series is optimized for low input current operation, making them ideal for energy-efficient designs. With a robust construction and wide operating temperature range, these optocouplers are well-suited for use in power supply feedback loops, microprocessor input interfaces, and signal isolation in noisy environments.
