IR’s 300V Power FETs Offer Benchmark Rds(on) to Improve Efficiency in Industrial Apps

International Rectifier Corp. (IR) has introduced of a family of 300V devices featuring IR’s latest power MOSFET silicon that deliver benchmark on-state resistance (Rds(on)) for a wide range of high efficiency industrial applications such 110-120 VAC line conditioners and 110-120 VAC power supplies, and DC to AC inverters including solar inverters and Uninterruptible Power Supplies (UPS). The new portfolio of power MOSFETs offers ultra-low Rds(on) to improve system efficiency and may allow designers to reduce part count where multiple MOSFETs are used in parallel.

The new devices are qualified to industrial grade and moisture sensitivity level 1 (MSL1), are offered lead free and are RoHS compliant. These devices include: The 40A IRFB4137PBF with an Rds(on) of 69mOhms and a Qg of 83 nC in a TO-220 package. The 40A IRFP4137PBF also with an Rds(on) of 69mOhms and a Qg of 83 nC in a TO-247 package. And the 70A IRFP4868PBF with an Rds(on) of 32mOhms and a Qg of 180nC in a TO-247 package.

“Featuring benchmark Rds(on) to deliver higher efficiency, power density and reliability, IR’s portfolio of 300V MOSFETs are well suited to industrial applications requiring greater system efficiency,” said Brian LaValle, Marketing Manager for IR’s Power Management Devices Business Unit.

Pricing for the IRFP4137PBF starts at $1.64 each in 10,000-unit quantities. Production orders are available immediately. Prices are subject to change.
