大量供应冠西 COSMO贴片光耦 :KMOC3021S The KMOC3021 series are optically isolated TRIAC driver devices. These series contain a GaAs infrared emitting diode and a light aivated silicon bilateral switch, which funions like a TRIAC. They are designed for interfacing between eleronic controls and power TRIACs to control resistive and induive loads for 115 VAC operations Features 1. Pb free and RoHS compliant 2. 400V peak blocking voltage 3. Simplifies logic control of 115 VAC power 4. Non zero voltage crossing 5. Isolation voltage between input and output (Viso:5300Vms)
