Vishay has broadened its optocoupler portfolio with two new IGBT and MOSFET drivers. The 2,5 A VO3120 and 0,5 A VO3150A combine a wide operating voltage with high ambient operating temperature ranges and low power consumption to enable thermal management and flexible design choices for motor drives, induction stove tops, power supplies and 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 V to 32 V. The voltage and current supplied by the new drivers make them suitable for directly driving IGBTs with ratings up to 800 V and 50 A for the VO3120 and 20 A for the VO3150A. Their operating voltage range of up to 32 V also allows them to drive larger modules that typically require a two-sided power supply.
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 heatsinks. Low power consumption of 2,5 mA also helps in minimising power and heat dissipation. Thermal models are available from Vishay to aid designers in performing thermal simulations.
