介绍压敏电阻的特点及应用
压敏电阻(Varistor)是一种电压敏感型电阻元件,当施加的电压超过其额定值时,电阻迅速减小,从而起到过电压保护作用。它广泛应用于电子设备中,防止电路因瞬态电压、浪涌电流或雷击等引发的损坏。本文中优恩半导体来为大家介绍压敏电阻的特点及应用,希望对各位工程师朋友有所帮助。

【技术】浅析瞬态抑制二极管(双向TVS管)
TVS管也叫瞬态抑制二极管,TVS管是吸收浪涌功率用的,能在极短时间内承受反向电压冲击,使两极间的电压钳位于一个特定电压上,避免后面的电路受到冲击。简单的说就是做过压保护的,在通信等产品中很常见。连接时必须反向工作在电路电源、地两端,与稳压二极管类似,但不需要限流电阻。

【经验】GDT放电管与MOV压敏电阻串联使用时是否导通在前?
GDT放电管与压敏电阻两个器件串联时,通常小容量的分压较高,大容量的分压较小,MOV压敏电阻的寄生电容是陶瓷气体放电管的百倍,因此绝大部分的电压会给到放电管,放电管导通之后,再施加到压敏电阻上,此时压敏电阻就会导通。
