Additional Details:

The FDW2507NZ typically features a drain-source voltage (VDS) rating of 25V and a continuous drain current (ID) rating that varies depending on the operating temperature and mounting conditions for each channel. The RDS(on) is typically in the milliohm range, contributing to lower power dissipation. The device is packaged in a Dual Cool 8 package. The gate threshold voltage (VGS(th)) is specified to ensure proper turn-on and turn-off characteristics. The device's thermal resistance characteristics are also important for thermal management in power applications. This dual MOSFET offers designers a combination of low on-resistance, fast switching, and efficient thermal performance in a space-saving package with enhanced thermal performance from the Dual Cool package. Its design is tailored to improve power density and efficiency in a variety of modern electronic systems.
