Nexperia unveils latest DFN MOSFETs

Nexperia has released a new range of 20V and 30V MOSFETs in what the company claims is the world’s smallest DFN package, the DFN0603.

Nexperia already offers ESD protection devices in this package but has now succeeded in bringing it to their MOSFET portfolio.

Next generation wearable and hearable devices are incorporating new levels of artificial intelligence (AI) and machine learning (ML), creating several challenges for product designers. Firstly, available board space is at a premium as functionality is added, plus heat dissipation becomes a problem as power consumption increases.

The ultra-low-profile DFN0603 package, measuring only 0.63 x 0.33 x 0.25 mm, uses 13% less space than MOSFETs in the next smallest package (DFN0604). This size reduction has been achieved without compromising device performance and the RDS(on) of these devices has been reduced by 74%, helping to improve efficiency and thereby enabling wearable equipment designers to achieve even greater power density.

This new range of MOSFETs includes:

  • PMX100UN 20 V, N-channel Trench MOSFET
  • PMX100UNE 20 V, N-channel Trench MOSFET with 2kV ESD protection (HBM)
  • PMX300UNE 30 V, N-channel Trench MOSFET
  • PMX400UP 20 V, P-channel Trench MOSFET

Nexperia has plans to add two more MOSFETs to this range later in 2022.
