Technical Specifications

The UT4812ZG-S08-R typically features a drain-source voltage (VDS) rating of 30V, a continuous drain current (ID) rating of around 8A, and a very low on-resistance (RDS(on)) value, potentially lower than the UT4812L-S08-R, which indicates a more efficient switch. However, it is crucial to consult the official datasheet for the exact RDS(on) value and other specifications. The device is packaged in an SOT-23-6 (S08) surface mount package. The gate threshold voltage is generally between 1V and 3V. Operating temperature range is typically -55°C to +150°C. Always refer to the manufacturer's datasheet for accurate and up-to-date specifications.
