Keywords:MOSFET driver  Vishay Green 

Vishay introduced its SMD low-profile 2.5A IGBT and MOSFET driver for motor drives, alternative energy, welding equipment and other high-working-voltage applications. Available in a 2.5mm height x 8mm profile, the VOL3120 provides isolation voltage ratings of VIORM = 1050V and VIOTM = 8,000V.

The height of the VOL3120 is 30 per cent lower than drivers in the standard DIP package, saving space and enabling flat-sized applications such as inductive stovetops and compact inverters used in domestic solar and motor drives. In addition to providing superior isolation, the VOL3120 also incorporates competitive electrical performance. The device's under-voltage lock-out feature protects the IGBT/MOSFET from malfunction, while its common mode transient immunity of more than 48kV/µs eliminates noise issues from low-voltage areas on the PCB.

The VOL3120's low current consumption of 2.5mA maximum makes it a practical choice in power design applications where high-efficiency operation is required. The device offers typical delays of less than 250ns and rise and fall times of 100ns typical, making it ideal for applications requiring fast switching of IGBTs or MOSFETs.

The driver operates with 15V to 32V power supply and a -4°C to 100°C temperature range. The VOL3120 offers a Moisture Sensitivity Level (MSL) of 1 in accordance to J-STD-020 and is RoHS-complaint, halogen-free and Vishay Green.

Samples and production quantities of the VOL3120 are available now, with lead times of eight to 10 weeks for larger orders.
