N-channel 100 V, 2.9 mOhm MOSFET with enhanced SOA in LFPAK88

N-channel enhancement mode MOSFET in a LFPAK88 package qualified to 175 °C. Part of Nexperia's Application Specific MOSFETs (ASFETs) for Hotswap and Soft Start. The PSMN2R9-100SSE delivers very low RDSon and enhanced safe operating area performance in a high-reliability copper-clip LFPAK88 package.

PSMN2R9-100SSE complements the latest "hot-swap" controllers - robust enough to withstand substantial inrush currents during turn-on, low RDSon to minimize I2R losses and deliver optimum efficiency when turned fully ON.

Features and benefits

  • Fully optimized Safe Operating Area (SOA) for superior linear mode operation

  • Low RDSon for low I2R conduction losses

  • LFPAK88 package for applications that demand the highest performance and reliability


  • Hot swap

  • Load switch

  • Soft start

  • E-fuse

  • Telecommunication systems based on a 48 V backplane/supply rail

As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: https://extranet.nexperia.com.

Sample orders normally take 2-4 days for delivery.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
