The VO2611-X017T is a single-channel optocoupler from Vishay with an open-drain output, rated for 10 MBd data rate and 5300 Vrms isolation. It is designed for high-speed digital isolation in industrial environments — think motor-drive feedback, PLC I/O modules, and isolated communication links where a clean logic-level signal must cross a safety barrier. The open-drain output gives it flexibility to interface with 5 V or 3.3 V logic families through a pull-up resistor, and the 23 ns rise / 7 ns fall times keep signal integrity tight at 10 MBd.
Isolation and transient immunity — the real-world specs
The 5300 Vrms isolation rating is the headline number for safety compliance in equipment with reinforced insulation requirements, such as motor drives and industrial power supplies. If your system sees fast common-mode edges from a motor-drive inverter or a flyback converter, this part holds the line without glitching the output.
Input-side LED forward voltage is 1.4 V typical, and the maximum DC forward current is 20 mA, which is standard for a photodiode-coupled optocoupler. Propagation delay is symmetrical at 100 ns max for both low-to-high and high-to-low transitions, which simplifies timing closure in synchronous designs.
