Introduction

The LTV-3120 series Photocoupler is ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications and inverters in power supply system. It contains an AlGaAs LED optically coupled to an integrated circuit with a power output stage. The 3.0A peak output current is capable of directly driving most IGBTs with ratings up to 1200 V/100 A. For IGBTs with higher ratings, the LTV-3120 series can be used to drive a discrete power stage which drives the IGBT gate. The Photocoupler operational parameters are guaranteed over the temperature range from -40°C~+110°C.
