Product Introduction

概述Description 

 QX3120 是一种输出电流为2.5A的栅极驱动光电耦合器,具有一个砷化铝镓(AlGaAs)的发光二极管,通过红 外光耦合到光敏集成电路。这种光电耦合器可驱动大多数的小功率IGBTs和MOSFETs。在电机控制逆变器以及高 性能电力系统应用中,非常适用于快速切换驱动功率IGBTs和MOSFETs。 

TheQX3120isagatedrivenoptocouplerwithanoutputcurrentof2.5A,withanAlGaAs LED,whichiscoupledtoa photosensitive integrated circuit through infrared light. This optocoupler can drive most low-power IGBTs and MOSFETs. In the motorcontrol inverter andhigh-performancepowersystem applications,it is very suitablefor fast switching drive powerIGBTsandMOSFETs.
