Optocoupler

Welcome to the Optocoupler (Optoisolator) department at Al-Hekmh Electronics. These specialized components use a beam of light to transmit electrical signals between two isolated circuits, providing robust galvanic isolation to shield sensitive low-voltage microcontrollers from high-voltage electrical noise and spikes in industrial, domestic, and educational applications.

Filter your search by matching your circuit parameters to our output configurations:

  • Standard Output Isolators: Find general-purpose Transistor output optocouplers for basic switching, along with pure Diode configurations tailored for high-speed linear signal transfer.
  • AC Power & Thyrsitor Control: Source reliable Triac and SCR output photocouplers, ideal for safely triggering high-power AC switches, solid-state relays, and phase-control circuits.
  • High-Speed Logic & Motor Driving: Explore high-speed Logic output units for data lines, along with rugged gate Drive optocouplers engineered specifically to feed the demanding capacitive inputs of high-power MOSFETs and IGBTs.

Available in a comprehensive variety of through-hole (DIP) and surface-mount (SMD) packaging configurations from the industry's leading semiconductor brands.
