Vishay Intertechnology has introduced a low-profile 2.5A IGBT and MOSFET driver which is ideal for motor drives, as well as for other applications handling high operating voltages, such as renewable-energy equipment and welding appliances.
The Vishay Semiconductors VOL3120 is housed in a compact LSOP-5 package which is just 2.5mm high, some 30% lower than equivalent drivers in a standard DIP package, yet it still provides a minimum 8mm clearance and external creepage distance. Its low profile makes it ideal for applications such as inductive stove tops and the compact inverters used in motor drives, in which space is at a premium.
The VOL3120 provides high isolation ratings of 1,050V, continuous, and 8,000V, transient.
In addition, its common-mode transient immunity of more than 48kV/μs means that noise is blocked from low-voltage areas of the PCB.
The device has an under-voltage lock-out feature which protects the IGBT or MOSFET from malfunctions, while the VOL3120’s maximum current requirement of 2.5mA makes it a viable choice for applications in which high efficiency is important.
The device boasts typical turn-on and turn-off delays of less than 250ns and typical rise and fall times of 100ns, important characteristics for applications with fast-switching IGBTs or MOSFETs.
