Photocoupler device ISOCOM IS341W for driving power IGBTs and MOSFETs in motor control applications
Product Overview
The ISOCOM IS341W Photocoupler is engineered for driving power IGBTs and MOSFETs in inverters for motor control and power supply systems. It features an AlGaAs LED optically coupled to an integrated circuit with a power output stage, capable of delivering a high peak output current of 3.0A. This enables direct drive of IGBTs up to 1200 V/100 A, or can be used to drive a discrete power stage for higher-rated IGBTs. The device is supplied in a Stretched SO6 package with wide lead separation, offering rail-to-rail output voltage and robust common mode rejection. It includes Under Voltage Lock Out (UVLO) protection with hysteresis and is guaranteed for performance across a wide temperature range, making it suitable for demanding industrial applications.
