Datasheet

Nexperia has announced the industry’s first AEC-Q101-qualified MOSFETs that are both rated for use at up to 175°C and are available in the AOI-compatible DFN2020 package. More, the devices measure just 2mm x 2mm, much smaller and lighter than SOT223 and SO8-packages yet with comparable electrical and thermal performance.

Many leadless packages cannot be inspected using AOI techniques, so Nexperia pioneered the development of the DFN2020 package with side-wettable flanks (SWF), enabling Automatic optical inspection (AOI) – a critical automotive industry requirement – to be employed. Packages with SWF are now a proven, accepted solution.

Comments Malte Struck, Nexperia’s product manager for small signal MOSFETs: “The DFN package with side-wettable flanks is gaining significant traction with automotive manufacturers as it saves space and can be automatically inspected. Our new 175 °C parts are being used in under-the-hood applications, especially near the engine or gearbox".

"The unique offering of an automotive-grade MOSFET that is both qualified to 175 °C and which incorporates side-wettable flanks makes the DFN2020 additionally suitable for a wide range of medium-power automotive applications.”

The automotive-qualified parts extend Nexperia’s low and medium power MOSFET portfolio. Six 40V and 60V devices are available with the higher temperature rating and automotive approval, each with low RDS(on) of between 20mΩ and 40mΩ.
