Specifications

The SUM75N04-05L-E3 features a drain-source voltage (VDS) of 40V and a continuous drain current (ID) of 75A. Its typical on-resistance (RDS(on)) is very low, around 5 mΩ at a gate-source voltage (VGS) of 10V, and even lower at lower VGS voltages relevant for the logic level gate drive. The gate threshold voltage (VGS(th)) is typically low, around 1-2V. This MOSFET is typically packaged in a TO-252 (DPAK) or similar package for efficient heat dissipation. Its operating junction temperature ranges from -55°C to +175°C, ensuring reliable performance in a wide range of operating conditions. The device is designed for surface mounting onto a PCB.
