【通信应用笔记】STBP120过电压保护装置 AN3050 Application note STBP120 overvoltage protection device 1 Introduction In order to reduce the power consumption, size and cost of electronic devices, most semiconductor components are manufactured using a “low voltage” process resulting in a maximum operating voltage of 7 V or even less. Any overvoltage causes an excessive power dissipation on the chip quickly leading to damage, or even electrical breakdown. Portable electronic devices, such……
