Inverter modules seal out moisture
New inverter modules combine IR's latest IGBT and soft recovery rectifier technology with a proprietary plastic package sealing method to protect components from environmental conditions.
International Rectifier has introduced two new near-hermetic, high-reliability motor control inverter modules that combine its latest IGBT and soft recovery rectifier technology with a proprietary plastic package sealing method to protect components from environmental conditions The new devices are designed to enhance three phase motor control circuits in electro-hydrostatic applications (EHA) such as critical flight controls for aircraft

MOSFETs improve 12V-input converter efficiency
Two new 20V HEXFET power MOSFET families from International Rectifier are designed to increase efficiency by up to 4% in 12V-input DC/DC convertors.
Other applications include aircraft braking and refueling systems, electric vehicle motor control, and ground vehicle power generation systems.
The IGBT modules come in the new INT-A-Pak 2 package, which uses an encapsulation process that protects circuitry from the harmful effects of moisture, and are screened to the stringent environmental test conditions of MIL-PRF-38534, Class H.
Components screened in accordance with these specifications meet the high reliability requirements demanded by the defense contractors supplying to commercial OEMs in vital safety applications and the US military.
In addition, these IGBT modules have passed double highly-accelerated stress testing (HAST).
In order to pass a HAST environmental test, IR's new INT-A-Pak 2 modules must withstand 85% relative humidity at 85C for 200 hours.
After 200 hours the modules meet all electrical performance tests, demonstrating robustness equivalent to a metal-welded hermetic device.
The new IGBT modules contain six IGBT switches in a three phase bridge configuration, or two switches per module in a single phase half bridge configuration.
The modules also contain Zener gate protection and operate over the full temperature range of -55 to +125C.
The G300HHCK12P2 half-bridge module is rated at 1200V, 300A, and the G450HHBK06P2 is rated at 600V, 450A.
