Vishay Releases New IGBT and MOSFET Drivers With 32-V Maximum Supply Voltage
Vishay Intertechnology, Inc. announced two new IGBT and MOSFET drivers. The 2.5A VO3120 and 0.5A VO3150A combine the widest operating voltage with high ambient operating temperature ranges and low power consumption to enable better thermal management and more flexible design choices for motor drives, induction stove tops, power supplies, and many other high-voltage applications.
The new VO3120 and VO3150A each consist of an LED optically coupled to an integrated circuit with a power output stage that has an operating voltage range of 15 to 32V. The VO3120 and the VO3150A feature an output current up to 2.5 and 0.5A respectively. The voltage and current supplied by the new drivers make them well suited for directly driving IGBTs with ratings up to 800V and 50A for the VO3120 and 20A for the VO3150A. Their operating voltage range of up to 32V, said to be the highest in the industry, allow the VO3120 and VO3150A to drive larger modules that typically require a two-sided power supply, thus giving designers more choices in selecting power components.
Both drivers feature a maximum ambient operating temperature of + 110°C, which simplifies thermal management by allowing designers to place them in closer proximity to IGBTs and/or to use smaller heat sinks. Low power consumption of 2.5mA also helps in minimizing power and heat dissipation. Thermal models are available from Vishay to aid designers in performing thermal simulations.
The VO3120 and VO3150A are offered in lead (Pb)-free and RoHS-compliant DIP-8 and SMD-8 versions. Samples are available now. Production quantities will be available in June 2009 with lead times of four to six weeks for production quantities. Pricing for U.S. delivery in 10,000-piece quantities is $1.09 for the VO3150A and $1.29 for the VO3120.
