The maximum operating temperature range for the STB21N65M5 is -40°C to 150°C.
To ensure proper biasing, the gate-source voltage (Vgs) should be between 2V and 10V, and the drain-source voltage (Vds) should be between 0V and 650V.
The recommended gate resistor value for the STB21N65M5 is between 1kΩ and 10kΩ, depending on the specific application and switching frequency.
To protect the STB21N65M5 from overvoltage and overcurrent, use a voltage clamp or a transient voltage suppressor (TVS) diode, and consider adding overcurrent protection circuitry, such as a fuse or a current sense resistor.
The maximum allowable power dissipation for the STB21N65M5 is 150W, but this can be increased with proper heat sinking and thermal management.
