WL-OCTR TRIAC Optocouplers

Würth Elektronik WL-OCTR TRIAC Optocouplers are designed as a safe alternative to mechanical relays, providing a solution for the phase control of AC loads. These TRIAC optocouplers utilize a TRIAC transistor controlled by an LED to manage various AC currents. The modules offer multiple options for off-state voltage (200V, 400V, and 600V) and triggering currents (5mA, 10mA, and 15mA), making them suitable for a wide range of applications. Supporting both through-hole (THT) and surface-mount (SMD) options, Würth WL-OCTR TRIAC Optocouplers are available in standard DIP4, DIP6, and SOP4 packages. Applications include white goods, AC motor drivers, static power switches, and temperature, light, and industrial controls.
