The thermal resistance of the WHAR10FET is typically around 1.5°C/W, but this can vary depending on the specific application and mounting method.
While the WHAR10FET is primarily designed for low-frequency applications, it can be used in high-frequency applications up to 100 kHz with some derating. However, it's essential to consult with Ohmite's application engineers to ensure the device meets the specific requirements.
To ensure proper heat sinking, it's recommended to use a thermal interface material (TIM) and a heat sink with a thermal conductivity of at least 1 W/m-K. The heat sink should be mounted using a torque of 5-10 in-lbs to ensure good thermal contact.
The maximum allowable voltage for the WHAR10FET is 100 V, but it's recommended to derate the voltage to 80 V or less to ensure reliable operation and minimize the risk of failure.
The WHAR10FET is rated for operation up to 150°C, but it's recommended to derate the power dissipation at higher temperatures to ensure reliable operation. Consult Ohmite's application engineers for specific guidance on high-temperature applications.
