International Rectifier has introduced the world's first 1000V radiation-hardened power MOSFET.
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.
They are offered with single or dual inputs, undervoltage lockout protection, fixed or programmable deadtime for half-bridge drivers, and drive currents up to 2.5A.
The new ICs use an advanced high-voltage IC process, known as G5 HVIC, which enables a host of new features and enhancements.
A next-generation high-voltage level-shifting and termination technology delivers superior electrical overstress protection and higher field reliability.

MOSFETs improve power density on both sides
New from International Rectifier are two TO-220-packaged HEXFET power MOSFETs that maximise power density and performance in primary- and secondary-side DC/DC convertor circuits.
Rad-hard MOSFETs protect and survive
With high radiation hardness and unparalleled single event effect (SEE) immunity, International Rectifier's new R5 MOSFETs are well suited for systems that must survive penetrating gamma rays.
The G5 HVICs have passed extensive quality and reliability testing.
Long-term reliability testing was performed to validate robustness beyond the expected useful lifetime of products in certain application environments.
This qualification required the devices pass several stress conditions including a 2000 hour, high-temperature biased test whereby the device's junction temperature exceeded datasheet specifications.
Additionally, the devices benefit from improvements in reliability due to silicon technology and packaging enhancements.
The advanced packaging equipment and materials, for example, combined with recent advancements in mould-compound injection techniques, allow these devices to be less sensitive to moisture and provide improvements in the plastic-to-die interface, an important consideration as peak soldering temperatures have increased with the adoption of lead-free soldering materials.
The surface mount SO-8 packages are qualified to MSL2 (moisture sensitivity level 2) while all other surface mount packages are MSL3 qualified.
All new HVICs are qualified to the J-STD-020C standard and comply with International Rectifier's environmental goals and policy.
International Rectifier's HVIC technology integrates N-channel and P-channel LDMOS circuitry in an intelligent driver IC.
The ICs receive a low-voltage input and provide gate drive and protection features for HV power-conditioning applications.
Additionally, these monolithic HVICs provide integration of features and functionality to simplify circuit design and reduce overall cost, including the option to use a low-cost bootstrap power supply which eliminates the need for the large and expensive auxiliary power supply that discrete optocoupler- or transformer-based designs typically require.
Production quantities are available immediately and the devices are RoHS compliant.
