Description

The CTW3120 consists of a GaAsP LED optically 

coupled to an integrated circuit with a power output 

stage. This optocoupler is ideally suited for driving 

power IGBTs and MOSFETs used in motor control 

inverter applications. The high operating voltage 

range of the output stage provides the drive 

voltages required by gate controlled devices. 

Applications 

• Isolated IGBT/Power MOSFET gate drive 

• Industrial Inverter 

• AC brushless and DC motor drives 

• Induction Heating
