New MOSFETs deliver low on-state resistance

International Rectifier (IR) introduces a dedicated family of automotive qualified MOSFETs for a range of applications requiring low on-state resistance (RDS(on)) including Electric Power Steering (EPS), Integrated Starter Alternator (ISA) pump and motor control, dc-dc conversion, battery switch, and other heavy loads on Internal Combustion Engine (ICE) and hybrid vehicle platforms.

The new devices, built on IR’s proven Gen 10.2 technology, deliver on-state resistance as low as 1.0 mOhm RDS(on) (maximum), and are available across a range of voltages from 24 to 100 V in a variety of Surface Mount Device (SMD) and through-hole packages. Several of the devices feature revised maximum current ratings of up to 240 A in a D2Pak-7P and 195 A in a D2Pak.

IR’s automotive MOSFETs are subject to dynamic and static part average testing combined with 100% automated wafer level visual inspection as part of the company’s automotive quality initiative targeting zero defects. AEC-Q101 qualification requires that there is no more than a 20% 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. The new devices are qualified according to AEC-Q101 standards and feature an environmentally friendly, lead free, and RoHS compliant Bill of Materials.
