Additional Details:

The SFU9214 typically has a drain-source voltage (VDS) rating of -200V, a continuous drain current (ID) rating that varies depending on temperature (check datasheet for specific values), and is available in a through-hole package such as TO-251 or TO-252. Its gate threshold voltage (VGS(th)) is usually between -2V and -4V. Detailed specifications, including thermal resistance and gate charge, can be found in the manufacturer's datasheet. When designing with this MOSFET, it's crucial to consider the thermal management to prevent overheating and ensure long-term reliability. Always consult the datasheet for the most accurate and up-to-date specifications.
