Details

The BSC0904NSH typically features a drain-source voltage (VDS) rating of 40V, and a continuous drain current (ID) of approximately 40A (depending on the specific conditions and heat sinking). The RDS(on) is very low, usually in the milliohm range, which minimizes conduction losses. The gate-source threshold voltage (VGS(th)) is also low, making it suitable for logic-level driving. Its avalanche rating ensures robustness against voltage spikes. It comes in a surface-mount package. This part is designed for high efficiency and reliability in demanding power applications.
