Additional Details:

The SI9428/TSM9428 typically features a drain-source voltage (VDS) rating of -30V and a continuous drain current (ID) rating that varies based on the specific package and operating conditions. The on-resistance (RDS(on)) is a key parameter, often specified at different gate-source voltages (VGS) to indicate performance under varying drive conditions. These MOSFETs are commonly available in surface-mount packages like SO-8, which aids in efficient heat dissipation. The gate threshold voltage (VGS(th)) is typically in the range that allows for direct logic level driving. The specific datasheet for either the SI9428 or TSM9428 should be consulted for precise electrical characteristics, thermal resistance, and package dimensions. The devices are designed to be RoHS compliant and lead-free, adhering to environmental regulations.
