Technical Specifications:

The SI7866DP-T1 features a drain-source voltage (VDS) of 30 V. The on-resistance (RDS(on)) is very low, typically in the milliohm range depending on the gate-source voltage (VGS). The gate threshold voltage (VGS(th)) is specified to ensure reliable turn-on and turn-off characteristics. It is surface-mounted and comes in a package (likely PowerPAK SO-8 or similar) optimized for heat dissipation. The operating temperature range typically spans from -55°C to +150°C.
