Low-Profile IGBT / MOSFET driver saves space in compact inverter designs

Aimed at motor drives, alternative energy, welding equipment and other high working voltage applications, Vishay has introduced a new low-profile surface-mount 2.5A IGBT and MOSFET driver. The VOL3120 features a small footprint with a 2.5mm height and minimum 8mm clearance and external creepage distance. In addition to its compact size, the device provides high isolation voltage ratings of VIORM = 1050 V and VIOTM = 8000 V, ideal for applications operating at higher working voltages and/or with higher pollution degree environments. The height of the VOL3120 is 30% 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 state-of-the-art 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 48 kV/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 boasts typical delays of less than 250ns and rise and fall times of 100 ns typical, making it ideal for applications where fast switching of IGBTs or MOSFETs is required. The driver released today operates over a wide power supply range of 15V to 32V and an industrial temperature range from -40C to +100C. Featuring an unlimited floor life, the VOL3120 offers a Moisture Sensitivity Level (MSL) of 1 in accordance to J-STD-020. The device is RoHS-complaint and halogen-free, says the company.
