STW7NK90Z Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the STW7NK90Z?
  The maximum operating temperature range for the STW7NK90Z is -40°C to 150°C.
• How do I ensure the reliability of the STW7NK90Z in high-temperature applications?
  To ensure reliability, it's essential to follow proper thermal management practices, such as providing adequate heat sinking, using thermal interface materials, and ensuring good airflow around the device.
• What is the recommended PCB layout for the STW7NK90Z to minimize electromagnetic interference (EMI)?
  To minimize EMI, it's recommended to use a multi-layer PCB with a solid ground plane, keep sensitive analog traces away from the device, and use shielding or filtering components as needed.
• Can I use the STW7NK90Z in a high-voltage application above 900V?
  No, the STW7NK90Z is rated for a maximum voltage of 900V. Exceeding this voltage can cause permanent damage to the device.
• How do I protect the STW7NK90Z from overcurrent and overvoltage conditions?
  Use a fuse or a current-limiting resistor in series with the device, and consider adding overvoltage protection (OVP) circuits or surge protection devices (SPDs) to prevent damage from voltage spikes or surges.
