定义
A power semiconductor device package is a protective enclosure that houses semiconductor chips (such as IGBTs, MOSFETs, diodes, thyristors), providing electrical interconnections through leads or terminals, efficient heat dissipation via thermal interfaces, and mechanical and environmental protection against moisture, contaminants, and physical damage. It ensures reliable operation under high voltage, high current, and high-temperature conditions in power electronics applications.
工作原理
The package functions by encapsulating the semiconductor die with insulating materials (e.g., epoxy, silicone), connecting it electrically via wire bonding or clip bonding to external terminals, and incorporating a thermal path (e.g., copper baseplate, heat sink) to dissipate heat generated during operation. It maintains electrical isolation, manages thermal expansion mismatches, and protects against environmental stressors to ensure long-term reliability.
