1. General description

N-channel enhancement mode MOSFET in a LFPAK56E package qualified to 175 °C. Part of

Nexperia's ASFETs for hotswap portfolio, the PSMN4R2-80YSE delivers very low RDSon and a

very strong linear-mode (SOA) performance in a high-reliability copper-clip LFPAK56E package.

PSMN4R2-80YSE complements the latest hot-swap controllers ‒ robust enough to withstand

substantial inrush currents during turn-on, low RDSon to minimize I2R losses delivering optimum

efficiency when turned fully ON and an 80 smaller footprint than existing D2PAK types.

2. Features and benefits

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

• Low RDSon for low I2R conduction losses

• LFPAK56E package for applications that demand the highest performance and reliability in a

30 mm2 footprint

3. Applications

• Hot swap

• Load switch

• Soft start

• E-fuse

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