CM1293数据手册电路保护的TVS-二极管规格书PDF

描述 Description

The CM1293 family of diode arrays has been designed to provide ESD protection for electronic components or sub-systems requiring minimal capacitive loading. These devices are ideal for protecting systems with high data and clock rates or for circuits requiring low capacitive loading. Each ESD channel consists of a pair of diodes in series which steer the positive or negative ESD current pulse to either the positive (VP) or negative (VN) supply rail. A Zener diode is embedded between VP and VN, offering two advantages. First, it protects the VCC rail against ESD strikes, and second, it eliminates the need for a bypass capacitor that would otherwise be needed for absorbing positive ESD strikes to ground.

特性 Features

• Eight channels of ESD protection
• PCI Express ports, Digital TV, Set Top Box, PC/Notebook, Gaming
• Low loading capacitance of 2.0pF max.
• Zener diode protects supply rail and eliminatesthe need for external by-pass capacitors
• Provides ESD protection to IEC61000-4-2 ±8kV
• Serial ATA ports in desktop PCs and hard disk drives

应用 Application

• General purpose high-speed data line ESD protection
