A good thermal design is crucial for high-power GaN devices. A 2-oz copper PCB with a large ground plane and multiple thermal vias is recommended. Ensure good thermal conductivity between the device and heat sink. Refer to Wolfspeed's application notes for more details.
Handle the device with ESD-protective equipment and follow proper ESD precautions. Use an ESD wrist strap or mat, and ensure the workspace is ESD-safe. Avoid touching the device's pins or exposed die.
A gate drive voltage of +5V to +10V is recommended, with a current capability of at least 1A. A high-current, low-impedance gate drive is essential for fast switching and low losses.
Ensure good thermal management, as mentioned earlier. Also, follow the recommended operating conditions, including voltage, current, and power dissipation. Avoid operating the device near its maximum ratings for extended periods.
To parallel devices, ensure identical thermal management, gate drive, and layout. Use a common gate drive signal and ensure the devices are matched in terms of threshold voltage and transconductance. Consult Wolfspeed's application notes for more information.
