CM1293电路保护的TVS-二极管规格书PDF中文资料

Product 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.

Features

• 2, 4, and 8 channels of ESD protection

• Provides ESD protection to IEC61000-4-2

- 8kV contact discharge

- 15kV air discharge

• Low loading capacitance of 2.0pF max.

• Low clamping voltage

• Channel I/O to I/O capacitance 1.5pF typical

• Zener diode protects supply rail and eliminates the need for external by-pass capacitors

• Each I/O pin can withstand over 1000 ESD strikes

• Available in SOT, and MSOP packages

• Lead-free version available

Applications

• DVI ports, HDMI ports in notebooks, set top boxes, digital TVs, LCD displays

• Serial ATA ports in desktop PCs and hard disk drives

• PCI Express ports

• General purpose high-speed data line ESD protection
