Note: Continuous use under heavy loads (e.g., high temperature/current/voltage, significant temperature changes) may significantly decrease product reliability, even if operating conditions are within absolute maximum ratings. Exceeding maximum ratings can cause device damage, permanent failure, and affect machine dependability. When designing circuits, do not exceed absolute maximum ratings. When installing heat sinks, pay attention to torsional moment and heat sink smoothness. MOSFETs are sensitive to static electricity; protect them from damage during use.
