International Rectifier (IR, El Segundo, CA) has introduced a HEXFET power MOSFET with a maximum temperature rating of 200 degrees C in a TO-220 plastic package. IR claims that the IRF1704 is an extremely rugged, low Rds(on) HEXFET power MOSFET manufactured using IR's stripe-planar technology, and is designed for existing and emerging automotive applications such as electric power steering, electro-hydraulic power-assisted steering, electric braking and electric valve operation.
Gordon Gray, technical marketing manager for the IR automotive group, commented, "While all applications can benefit from devices with a higher junction-operating temperature, the automotive industry has a more obvious and compelling need for high-temperature MOSFETs. The IRF1704 can increase safety, reliability and overload survivability in under-hood applications."
Pricing for the IRF1704 is $2.10 each in 10,000-unit quantities. Samples are now available.
