IGBT and diode run cooler together for
driving
International Rectifier's has a new family of 600V short-circuit-rated IGBT/FRED copackaged devices for sub-two-horsepower industrial and appliance motor drives.
International Rectifier's new family of 600V short-circuit rated IGBT/FRED copackaged devices for sub-two-horsepower industrial and appliance motor drives offers 18% lower saturation voltage (VCE(on)) than previous generation short-circuit rated devices The family also features the industry's lowest VCE(on) for short-circuit-rated copackaged IGBTs

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.
The lower saturation voltage of the new M Series of 600V short-circuit-rated IGBT/FRED copackaged devices reduces conduction losses by up to 25% at 50% duty cycle operating conditions.
This allows designers to reduce heatsink size to achieve more compact and cost effective designs.
M Series devices further simplify design and reduce circuit size thanks to their simplified driver requirements.
The short-circuit capability protects the devices during circuit faults or abnormal operation for improved ruggedness of the motor drive.
Devices in IR's M Series offer a VCE(on) as low as 1.85V at 100C and have a 10ms short circuit capability at full 15V gate drive (VGE) input.
The new devices are optimised to minimising switching losses in the 4-10kHz operating frequency range and are specifically designed for use in the bridge configurations typically found in motor drives.
The IGBTs are copackaged with HEXFRED ultrafast ultrasoft-recovery antiparallel diodes that reduce or eliminate snubber components and minimise switching losses, noise and EMI.
The M Series IGBTs feature very low shoot-through current in the absence of turn-off bias unlike other IGBTs available on the market.
As a result, they simplify the drive circuit by eliminating the need for a negative bias power supply.
The M Series IGBTs can easily be used with high voltage gate driver ICs to further simplify circuit design and cut circuit size.
