SMF78AT1G电路保护的TVS-二极管规格书PDF中文资料

SMF78AT1G属于电路保护的TVS-二极管。由安森美半导体公司制造生产的SMF78AT1GTVS - 二极管TVS 二极管是一种半导体器件，可用于限制或阻止特定电压电平的浪涌。该系列产品使用二极管（只能单向导电的元器件）进行设计。TVS 是 Transient Voltage Suppression/Suppressor（瞬态电压抑制/抑制器）的首字母缩写。类型包括转向（轨至轨）或齐纳，具有单向通道、双向通道、电压 – 反关态、电压 – 击穿、电压 – 箝位、电流 – 峰值脉冲、功率 – 峰值脉冲和电源线路保护等特征。

Zener Transient Voltage Suppressor SOD−123 Flat Lead Package

The SMF5.0A Series is designed to protect voltage sensitive components from high voltage, high energy transients. Excellent clamping capability, high surge capability, low zener impedance and fast response time. Because of its small size, it is ideal for use in cellular phones, portable devices, business machines, power supplies and many other industrial/consumer applications.
