大量供应冠西 COSMO可控硅光耦： KMOC3021
The KMOC3021 series are optically isolated TRIAC driver devices. 
These series contain a GaAs infrared emitting diode 
and a light activated silicon bilateral switch, which 
functions like a TRIAC. They are designed for 
interfacing between electronic controls and power 
TRIACs to control resistive and inductive 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
