Additional Details:

The SI9430DY-T1 typically has a drain-source voltage (VDS) rating of -30V and is commonly available in a surface-mount package such as SO-8. The on-resistance (RDS(on)) is specified at different gate-source voltages (VGS) in the datasheet. The '-T1' suffix usually indicates tape and reel packaging for automated assembly. The gate threshold voltage (VGS(th)) is designed for logic-level gate drive. The datasheet should be consulted for precise electrical characteristics, thermal resistance, and package dimensions. It is RoHS compliant and lead-free, adhering to environmental standards.
