40-V to 200-V family of automotive-qualified MOSFETs offer benchmark on-state resistance performance

September 08, 2011 // By Paul Buckley
International Rectifier has introduced a family of automotive-qualified MOSFETs delivering benchmark on-state resistance (Rds(on)) for a range of applications including electric power steering (EPS), integrated starter alternator (ISA) pump and motor control, and other heavy loads on internal combustion engine (ICE) and hybrid vehicle platforms.

The new family of trench HEXFET power MOSFETs is available across a range of voltages from 40 V to 200 V in a variety of surface mount device (SMD) packages. Both standard and logic level gate drive MOSFETs set a new standard of Rds(on) performance for IR’s automotive plastic package MOSFET portfolio. Benchmark Rds(on) as low as 1.25 mohm max at 40 V, 2.1 mohm max at 60 V, 2.6 mohm max at 75 V and 4.0 mohm max at 100 V can be achieved. A number of the devices feature a maximum current rating of up to 240 A in a D2Pak-7P.

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 begins at US $0.34 each for the AUIRFS3806 in 100,000-unit quantities and US $1.41 each in 100,000-unit quantities for the AUIRLS4030-7P. Production orders are available immediately.
