Product Description
The CM1203 comprises a family of 1, 2, and 3-channel ESD protection arrays, which integrate two, three and four identical avalanche-style diodes. It is intended that one of these diodes is connected to GND and the other diodes provide ESD protection for up to 3 lines depending upon the configuration utilized. The backto-back diode connections provide ESD protection for nodes that have AC signals up to 5.9V peak. These devices provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The diodes are designed and characterized to safely dissipate ESD strikes of ±15kV, well beyond the maximum requirements of the IEC 61000-4-2 international standard.
