Würth Elektronik WL-OCHS High-Speed Optocouplers

Würth Elektronik WL-OCHS High-Speed Optocouplers are designed to expand the portfolio with reliable galvanic isolation solutions for fast digital communication. These optocouplers support data rates from 1MBd up to 10MBd combines fast switching times from 20 ns to 800 ns for precise signal transmission. The WL-OCHS optocouplers offer high isolation voltages of 3750VRMS and 5000VRMS.  With high noise immunity enabled by strong CMTI performance and low internal coupling capacitance, WL-OCHS is well suited for applications such as industrial controls and automation.
