IR’s Family of Rugged 40 V to 75 V Automotive-qualified MOSFETs Deliver Low On-State Resistance for Heavy Load Applications

The new rugged planar devices feature low RDS(on) and are available across a range of voltages from 40V to 75 V in a variety of Surface Mount Device (SMD) and through-hole packages. The AUIRL1404S is a logic level gate drive MOSFETs offered at 40 V and other devices included in the new family are standard gate drive MOSFETs offered at 40 V, 55 V and 75 V.

“Featuring IR’s proven technology, these rugged new planar MOSFETs offer good performance in linear mode operation. The wide voltage range also makes them well suited to applications on vehicles using a higher board-net voltage such as trucks,” said Jifeng Qin, product manager, IR’s Automotive Products Business Unit.

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.
