The maximum operating temperature of the STP20NM60 is 150°C, as specified in the datasheet.
To ensure proper cooling, a heat sink with a thermal resistance of less than 10°C/W is recommended. Additionally, ensure good thermal contact between the device and heat sink using a thermal interface material.
The maximum current rating of the STP20NM60 is 20A, as specified in the datasheet. However, this rating is dependent on the device's operating temperature and the PCB's thermal design.
To protect the STP20NM60 from overvoltage and overcurrent, use a voltage regulator or a voltage clamp to limit the voltage across the device. Additionally, consider using a current sense resistor and a fuse or a current limiter to prevent overcurrent conditions.
The recommended gate drive voltage for the STP20NM60 is between 10V and 15V, as specified in the datasheet. A higher gate drive voltage can improve the device's switching performance.
