Technical Specifications:

The SQD50N04-4M5L-GE3 has a drain-source voltage (V<sub>DSS) of 40V and a continuous drain current (I<sub>D) of 50A. The on-resistance (R<sub>DS(on)) is typically around 4.5 mΩ (milliohms) at V<sub>GS = 10V. The gate threshold voltage (V<sub>GS(th)) is typically between 1V and 3V. The total gate charge (Q<sub>g) is around 20 nC. The operating junction temperature range is -55°C to +175°C.

The package is a PowerPAK® SO-8 single package, designed for surface mount assembly. It's crucial to provide adequate heatsinking to manage the heat generated during operation at higher current levels. The gate-source voltage (V<sub>GS) should be kept within the specified limits to avoid damaging the device. The device is RoHS compliant.
