CM1205 ESD Protection Arrays, Chip Scale Package Features Product Description • The CM1205 family of transient voltage suppressor arrays provides a very high level of protection for sensitive electronic components that may be subjected to ESD. • • • • • Functionally and pin compatible with CAMD’s PACDN1404C, PACDN1408C and PACDN1416C family of ESD protection devices 4, 8, or 16 transient voltage suppressors in a single package OptiguardTM coated for improved reliability at assembly In-system Electrostatic Discharge (ESD) protection to +25kV contact discharge per IEC 61000-4-2 international standard Compact Chip Scale Package (0.65mm pitch) format saves board space and eases layout in space critical applications compared to discrete solutions and traditional wire bonded packages Lead-free versions available These devices are designed and characterized to safely dissipate ESD strikes at levels well beyond the maximum requirements set forth in the IEC 61000-4-2 international standard (Level 4, +8kV contact discharge). All I/Os are rated at +25kV using the IEC 61000-4-2 contact discharge method. Using the MILSTD-883D (Method 3015) specification for Human Body Model (HBM) ESD, all pins are protected for contact discharges to greater than +30kV. The Chip Scale Package format of these devices enable extremely small footprints that are necessary in portable electronics such as cellular phones, PDAs, internet appliances and PCs. The large solder bumps allow for standard attachment to laminate boards without the use of underfill. Applications • • • • • • • • ESD protection for sensitive electronic equipment I/O port, keypad and button circuitry protection for portable devices Wireless Handsets Handheld PCs / PDAs MP3 Players Digital Cameras and Camcorders Notebooks Desktop PCs The CM1205 features OptiGuardTM coating for improved reliability at assembly and is available with optional lead-free finishing.
