The thermal resistance of the WNBR25FET is typically around 1.5°C/W, but this can vary depending on the specific application and mounting method. It's recommended to consult with Ohmite's application engineers for more detailed information.
While the WNBR25FET is primarily designed for low-frequency applications, it can be used in high-frequency applications up to 100 kHz with some limitations. However, the device's performance may degrade at higher frequencies, and additional considerations such as parasitic inductance and capacitance should be taken into account.
Ohmite recommends using a heat sink with a thermal interface material (TIM) to ensure optimal thermal performance. The device should be mounted using a screw or clip to ensure good mechanical contact and to prevent thermal runaway.
The WNBR25FET is rated for operation up to 150°C, but its performance may degrade at higher temperatures. For high-temperature applications above 125°C, Ohmite recommends using a derating curve to ensure the device operates within its safe operating area.
The WNBR25FET is rated for a maximum voltage of 25V, but it can be used in high-voltage applications with proper derating and snubber circuits to prevent overvoltage stress. However, it's essential to consult with Ohmite's application engineers to ensure the device is used within its safe operating area.
