IR Introduces Benchmark Industrial-Grade 30V MOSFETs

EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced a series of industrial-qualified 30V TO-220 HEXFET® power MOSFETs with extremely low gate charge (Qg) for applications including Uninterruptable Power Supply (UPS) inverters, low voltage power tools, ORing applications and netcom and server power supplies.

The robust MOSFETs feature IR’s latest generation Trench technology and offer very low on-state resistance (RDS(on)) to reduce thermal dissipation. In addition, the new devices’ ultra low gate charge helps extend battery life of UPS inverters or power tools.

“The new devices offer the best cost and performance tradeoff. Moreover, by offering four levels of RDS(on) and Qg at a 30V level, the devices provide design engineers with the flexibility to select the optimum device to match their specifications and requirements for the application,” said Hemal Shah, marketing manager for IR’s Power Management Devices Business Unit.

The new MOSFETs feature fully characterized avalanche voltage and current and are direct replacements and upgrades to existing 30V TO-220 devices as IR continues to develop benchmark MOSFETs.

The devices are qualified to industrial grade and moisture sensitivity level 1 (MSL1). The 30V MOSFETs are available in a TO-220 package, are offered lead free and are RoHS compliant.
