Additional Details

The IRFU3518PBF is typically packaged in a TO-251 (IPAK) or TO-252 (DPAK) package, offering good thermal performance. Key specifications include its drain-source voltage (VDS), gate-source voltage (VGS), continuous drain current (ID), and pulsed drain current (IDM). The datasheet provides detailed information on these parameters, including thermal resistance, gate charge, and diode characteristics. The gate threshold voltage (VGS(th)) is an important parameter for proper biasing and control. It is designed for through-hole mounting.
