Rugged, Reliable Automotive-Qualified Power MOSFETs in TO-220 Package

International Rectifier, IR, introduced a family of automotive-qualified power MOSFETs housed in a rugged TO-220 fullpak package for automotive applications including BLDC motors, pumps and cooling systems. The new 55V planar devices are available as standard and logic level gate drive MOSFETs in N and P channel configuration, and offer a maximum on-state resistance (Rds(on)) as low as 8mOhm. The TO-220 fullpak package eliminates the need for additional insulating hardware to simplify design and improve overall system reliability.

IR's automotive MOSFETs are subject to dynamic and static part average testing combined with 100 percent automated wafer level visual inspection as part of IR's automotive quality initiative targeting zero defects. AEC-Q101 qualification requires that there is no more than a 20 percent change in Rds(on) after 1,000 temperature cycles of testing. However, in extended testing IR's new AU bill of materials demonstrated a maximum Rds(on) shift of less than 10% at 5,000 temperature cycles, showing the strength and ruggedness of the bill of materials.

The new devices are qualified according to AEC-Q101 standards, feature an environmentally friendly, lead-free and RoHS compliant bill of materials.

Pricing ranges from US $0.37 each for the AUIRFIZ34N in 100,000-unit quantities to US $0.78 each in 100,000-unit quantities for the AUIRFI4905. Production orders are available immediately. Prices are subject to change.
