WHD5K0FET - Ohmite

WHD5K0FET Frequently Asked Questions (FAQs)

• What is the thermal resistance of the WHD5K0FET?
  The thermal resistance of the WHD5K0FET 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.
• Can I use the WHD5K0FET in a high-frequency application?
  While the WHD5K0FET 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.
• How do I ensure reliable soldering of the WHD5K0FET?
  To ensure reliable soldering, follow Ohmite's recommended soldering profile: 260°C peak temperature, 3°C/s ramp rate, and 10-15 seconds dwell time. Additionally, use a solder with a melting point above 180°C and a flux that is compatible with the device's terminations.
• What is the recommended torque for mounting the WHD5K0FET to a heat sink?
  The recommended torque for mounting the WHD5K0FET to a heat sink is 8-10 in-lbs (0.9-1.1 Nm) to ensure proper thermal contact and prevent damage to the device.
• Can I use the WHD5K0FET in a high-voltage application?
  The WHD5K0FET is rated for a maximum voltage of 500V. While it can be used in high-voltage applications, it's essential to ensure that the device is properly derated and that the system is designed to handle voltage transients and spikes.
