25 V and 30 V MOSFET in high current density handling PQFN package
International Rectifier (IR) has released a family of 25 V and 30 V MOSFETs in PQFN 3 x 3 package for use as DC-DC converter switches in telecom, netcom, and high-end desktop and notebook computer applications.
These MOSFETs with low on resistance are designed to handle higher load current capability than standard PQFN 3 x 3 devices and are qualified to industrial standard and moisture sensitivity level 1 (MSL1).
The performance PQFN package technology is also applied to 5 x 6 mm footprint devices enabling designs requiring more current without the need for additional footprint compared to standard PQFN 5 x 6 devices.
The family includes devices optimized for use as control MOSFETs featuring low gate resistance (Rg) to reduce switching losses. For synchronous MOSFET use, devices are available as a FETKY (monolithic FET and Schottky diode) configuration to offer enhanced efficiency and EMI performance by reducing reverse recovery time.
"The new family of performance PQFN package devices offers a high density, highly reliable and flexible solution optimized for DC-DC applications. Moreover, by expanding IR's PQFN offering, customers can now select from many package combinations to achieve the optimal result for their design," said George Feng, marketing engineer for IR's Power Management Devices Business Unit.
With a low profile of less than 1 mm, the devices are compatible with existing Surface Mount Techniques, feature industry-standard footprint and are RoHS compliant.
