Additional Details

The SUP90N04-3m3P features an exceptionally low on-resistance (RDS(on)) of typically 3.3 mΩ at a gate-source voltage (VGS) of 10 V and a drain current (ID) of 25 A. At a VGS of 4.5 V and a drain current (ID) of 20 A, the typical RDS(on) is slightly higher but still very low. The gate threshold voltage typically falls between 1 V and 2.5 V. The device is designed to operate within a temperature range of -55 °C to +175 °C. Its thermal resistance from junction to ambient is approximately 50 °C/W. The device's input capacitance is around 2000 pF, and its gate charge is around 20 nC. This MOSFET is designed to provide an exceptionally efficient and reliable solution for power management applications where minimizing power loss is critical.
