ASFETs for Power over Ethernet (PoE)

Enhanced SOA, enhanced protection, low RDS(on), and superior power density

The latest high-power 48V Power over Ethernet standard (IEEE 802.3bt) and proprietary approaches are enabling the next generation of PoE systems. Such systems can deliver up to 100 W to each powered device, including large screen LCD displays, 5G pico-cells, advanced Wi-Fi hot-spots and pan-tilt-zoom CCTV cameras. This places increased demands on PoE power sourcing equipment (PSE). Demands that are matched by Nexperia’s dedicated PoE MOSFET family.

ASFETs for Power over Ethernet (PoE) have been specifically designed to complement the latest high-power, PSE controllers:

  • MOSFET’s primary role is to safely manage inrush current when capacitive loads are added to the network
  • Extended enhanced Safe Operating Area (SOA) to withstand power dissipation due to short-circuit fault conditions until the PSE controller detects the fault and switches off 
  • Enhanced protection – our MOSFETs offer more than 2x the protection of competitive devices. During a cable short fault, our ASFETs for PoE can safely dissipate up to 30 W under +60 °C ambient for up to 20 ms  
  • To squeeze more high-power PoE ports into a compact router / switch requires superior power density offered by the thermal efficiency and compact footprint of the LFPAK33 package
