Vishay TCDT1100(G) Series Optocoupler Datasheet
The TCDT1100(G) Series optocouplers consist of a phototransistor optically coupled to a gallium arsenide infrared‑emitting diode in a 6‑lead plastic DIP package. They are designed for reinforced isolation in safety class II applications, supporting mains voltages up to 600 V and complying with VDE 0884 and other safety standards.
The datasheet details electrical characteristics such as forward voltage, current transfer ratio, and isolation ratings, as well as switching times, typical performance curves, and mechanical dimensions. It also includes safety ratings, approval markings, and recommended operating conditions for reliable use in power supplies, line receivers, and microprocessor interfaces.
