The thermal resistance of the WHE10KFET is typically around 1.5°C/W (junction-to-case) and 5°C/W (junction-to-ambient) at a maximum operating temperature of 150°C.
While the WHE10KFET is primarily designed for low-frequency applications, it can be used in high-frequency applications up to 100 kHz with proper PCB design and layout considerations. However, it's essential to consult with Ohmite's application engineers for specific guidance.
To ensure reliable soldering, follow Ohmite's recommended soldering profile: peak temperature of 260°C, dwell time of 10-15 seconds, and a soldering iron with a temperature range of 200-240°C. Additionally, use a solder with a melting point above 180°C and a flux that is compatible with the device's materials.
Ohmite recommends using a screw-down or clip-mounting method to ensure proper thermal contact and mechanical stability. The device should be mounted on a heat sink or a metal plate with a thermal interface material (TIM) to improve heat dissipation.
The WHE10KFET is rated for a maximum voltage of 1000V, but it's essential to consider the device's derating curves and ensure that the operating voltage is within the recommended range to prevent premature failure or damage.
