Technical Specifications:

The UT9435HG-S08-R typically features a drain-source voltage (VDS) rating, a gate-source voltage (VGS) rating, and a continuous drain current (ID) rating. The on-resistance (RDS(on)) is a crucial parameter for determining power loss. The S08 package offers good thermal performance for its size. The gate threshold voltage (VGS(th)) is an important parameter for logic-level gate drive applications.
