Standard level N-channel MOSFET in a D2PAK package qualified to 175 °C. Part of Nexperia's "NextPower Live" portfolio, the PSMN4R8-100BSE complements the latest "hot-swap" controllers - robust enough to withstand substantial inrush currents during turn on, whilst offering a low R_DS(on) characteristic to keep temperatures down and efficiency up in continued use. Ideal for telecommunication systems based on a 48 V backplane / supply rail.
