Technical Specifications

The SI9802DY-T1 typically features a drain-source voltage (VDS) rating of -20V to -30V, a gate-source voltage (VGS) rating of ±12V to ±20V, and a continuous drain current (ID) rating in the range of -3A to -6A, depending on the operating conditions and package. The RDS(on) is usually very low, typically less than 0.1 ohms, to minimize power loss during switching. It is commonly available in a SOIC-8 package.

Being a P-Channel MOSFET, the SI9802DY-T1 is particularly useful in high-side switching applications where a ground-referenced control signal is desired. The low on-resistance contributes to its high energy efficiency. The surface-mount package facilitates automated assembly and contributes to a compact design. The fast switching speed makes it suitable for high-frequency DC-DC converters. The device's avalanche energy rating ensures robustness and reliability in demanding applications.
