Additional Details:

The UPA1793 typically has a drain-source voltage (VDS) rating of -20V to -30V. Continuous drain current (ID) ratings vary based on the package and operating temperature, but are typically in the range of several amperes. Gate-source voltage (VGS) ratings are typically ±20V. The on-resistance RDS(on) is a crucial parameter and can be found in the Renesas datasheet along with gate charge, and thermal resistance. The operating temperature range is typically -55°C to +150°C. Refer to the Renesas Electronics datasheet for specific values.
