Vishay Semiconductors VOx619A Phototransistor Output Optocouplers
Vishay Semiconductors VOx619A 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 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.
