Thermal Management: Use proper heatsinks or oil cooling to maintain safe junction temperature.
Voltage Margin: Design with 10–20% safety margin below 4800 V.
Surge Protection: Include snubber networks or fast fuses to suppress transients.
Series/Parallel Matching: Ensure balanced voltage or current distribution.
Insulation: Maintain sufficient creepage and clearance distances.
Operation Life: Avoid continuous operation near rated limits.
Periodic Inspection: Monitor leakage current, temperature, and forward voltage drop regularly.
