GE输入IC693ALG391CA

IC693ALG391CA压敏电阻是一种特殊的电阻，压敏电阻器的电压与电流不遵守欧姆定律，而成特殊的非线性关系。当两端所加电压低于标称额定电压值时，压敏电阻器的电阻值接近无穷大，内部几乎无电流流过;当两端所加电压略高于标称额定电压值时，压敏电阻器将迅速击穿导通，并由高阻状态变为低阻状态，工作电流也急剧增大;当两端所加电压低于标称额定电压值时，压敏电阻器又恢复为高阻状态;当两端所加电压超过大限制电压值时，压敏电阻器将完全击穿损坏，无法再自行恢复。

压敏电阻主要用于瞬时过电压的保护，起过电压保护、防雷、抑制浪涌电流、吸收尖峰脉冲、限幅、高压灭弧、消噪、保护半导体元器件等。当瞬时电压尖峰超过压敏电阻的耐压时，压敏电阻导通，将与其并联的器件旁路，从而避免了器件被过电压击穿。主要用在交流输入侧对整流桥进行保护。
