SMF12电路保护的TVS-二极管规格书PDF中文资料

SMF12属于电路保护的TVS-二极管。由升特制造生产的SMF12TVS - 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。

Description

The SMF series TVS arrays are designed to protect sensitive electronics from damage or latch-up due to ESD and other voltage-induced transient events. They are designed for use in applications where board space is at a premium. Each device will protect up to four lines. They are unidirectional devices and may be used on lines where the signal polarities are above ground.

TVS diodes are solid-state devices designed specifically for transient suppression. They feature large cross-sectional area junctions for conducting high transient currents. They offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation.

The SMF series devices may be used to meet the immunity requirements of IEC 61000-4-2, level 4. The small SC70 package makes them ideal for use in portable electronics such as cell phones, PDA’s, notebook computers, and digital cameras.
