CM1214A中文资料交流信号 ESD 保护器数据手册ONSEMI规格书

描述 Description

The CM1214A ESD protector is used to protect bipolar signal lines against electrostatic discharge (ESD). The CM1214A allows operation in high-speed environments with signals levels up to ±5V. The low sub-1pF loading capacitance makes the CM1214A-01SO ideal for protecting high-speed interfaces including RF switches and amplifiers.The CM1214A-02MR is ideal for dual high-speed signal pairs used in Gigabit Ethernet, ADSL, etc. The CM1214A-02MR can also be used for higher transmit voltage applications by connecting the two channels in series.

特性 Features

• Single channel ESD protection for an AC signal up to ±5 V for 0.25 W transmit power
• Connects two channels in series for signals up to 10 V (1 W transmit power)

应用 Application

• RF modules and RF IC protection,High-speed AC signals for Gbit ethernet
• Wireless handsets, Netbook

简介

CM1214A属于电路保护的TVS-二极管。由制造生产的CM1214ATVS - 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。
