Description

The CT3120 consists of a 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
