Vishay’s VOFD341A and VOFD343A IGBT and MOSFET drivers, available in stretched SO-6 packages, provide peak output current of up to 4 A. Their high peak output current allows for faster switching by eliminating the need for an additional driver stage. Each device contains an AlGaAs LED optically coupled to an integrated circuit with a power output stage, specifically designed for driving power IGBTs and MOSFETs in motor control inverters.
The drivers support an operating voltage range of 15 V to 30 V and feature an extended temperature range of -40°C to +125°C, ensuring a sufficient safety margin for more compact designs. They also have a maximum propagation delay of 200 ns, which minimizes switching losses and facilitates more precise PWM regulation.
Additionally, the drivers’ high noise immunity of 50 kV/µs helps prevent failures in fast-switching power stages. Their stretched SO-6 package provides a maximum rated withstanding isolation voltage of 5000 VRMS.
Samples and production quantities of the 3-A VOFD341A and 4-A VOFD343A are available now, with lead times of six weeks.
