Nexperia launched a new AEC-Q101-qualified Repetitive Avalanche Application Specific FET (ASFET) portfolio focused on powertrain applications.
The technology has been tested to one billion avalanche cycles and can be used to control automotive inductive loads such as solenoids and actuators. In addition to providing a faster turn-off time (up to 4X), designs can be simplified through a reduced BOM count.
Fully automotive qualified to AEC-Q101 at 175 °C, the new MOSFETs are available in 40 V and 60 V options with typical RDS(ON) ratings from 12.5 mΩ to 55 mΩ.
All of the devices are supplied in the company’s space-saving LFPAK56D (Dual Power-SO8) copper-clip package technology. The highly robust package features gull wing leads for increased board level reliability, and improved manufacturability including automated optical inspection (AOI).
Explains Nexperia’s Product Manager, Richard Ogden “Typically, engineers looking to implement repetitive avalanche topologies have had to rely on devices that use older, planar semiconductor technologies. Offering automotive-qualified devices with guaranteed repetitive avalanche capabilities that are based on higher performance silicon structures will increase the number of powertrain designs that can take advantage of repetitive avalanche functionality.”
