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 back-to-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 CM1203 safely dissipates ESD strikes of ±15kV, well beyond the maximum requirements of the IEC 61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, these devices protect against contact discharges of greater than ±30kV. The diodes also provide some EMI filtering, when used in combination with a PCB trace or series resistor.

CM1203 are particularly well-suited for portable electronics (e.g. cellular telephones, PDAs, notebook computers) because of their small package format and easy-to-use pin assignments.

The CM1203 incorporates OptiGuard™ coating which results in improved reliability at assembly. The CM1203 is available in a space-saving, low-profile, chip-scale package with optional lead-free finishing.
