Vishay's New IGBT and MOSFET Drivers: Enabling Compact, Efficient, and High-Voltage Solutions

Vishay Intertechnology, Inc. (NYSE: VSH) has recently introduced two new IGBT and MOSFET drivers, the VOFD341A and VOFD343A, in a compact, high isolation stretched SO-6 package. These drivers offer high peak output currents, high operating temperatures, low propagation delay, and high noise immunity, making them ideal for various applications such as solar inverters, microinverters, AC and brushless DC industrial motor control inverters, and inverter stages for AC/DC conversion in UPS. This article explores the features and benefits of these new drivers and their potential impact on the semiconductor market.


The VOFD341A and VOFD343A drivers' high operating temperatures up to +125 °C provide a higher temperature safety margin, enabling more compact designs. Their high peak output currents of 3 A and 4 A, respectively, allow for faster switching by eliminating the need for an additional driver stage. The low propagation delay of 200 ns maximum minimizes switching losses and facilitates more precise PWM regulation. These features contribute to the market appeal of these drivers, as they enable more efficient and compact designs in various applications.

The new drivers' compatibility with high voltage inverter stages and high noise immunity further enhance their integration into various applications. The high isolation package enables working voltages up to 1.140 V, allowing for high voltage inverter stages while maintaining enough voltage safety margin. The high noise immunity of 50 kV/µs prevents fail functions in fast switching power stages, ensuring reliable operation in demanding environments.


Vishay's portfolio expansion with these new drivers influences its competitive position in the semiconductor market by addressing the growing demand for compact, efficient, and high-voltage solutions. The potential applications and market segments for these drivers include solar inverters, industrial motor control, and AC/DC conversion in UPS, among others. As the demand for renewable energy and energy-efficient solutions continues to grow, these new drivers are well-positioned to capture market share in these segments.

In conclusion, Vishay's new IGBT and MOSFET drivers in the stretched SO-6 package offer a compelling combination of features that enable compact, efficient, and high-voltage solutions. Their high operating temperatures, low propagation delay, compatibility with high voltage inverter stages, and high noise immunity make them an attractive choice for various applications. As the demand for energy-efficient and renewable energy solutions continues to grow, these new drivers are poised to play a significant role in the semiconductor market.
