| CALIFORNIA MICRO DEVICES PAC DN027 Applications ESD protection of PC parallel ports. Protection of interface ports or IC pins which are exposed to high levels of ESD discharge. 17-CHANNEL TRANSIENT VOLTAGE SUPPRESSOR ARRAY Features 17 transient voltage suppressors in a single package. In-system ESD protection to 30KV contact discharge per IEC 61000-4-2 International Standard. Compact 20-pin QSOP package saves board space and eases layout in space critical applications. Product Description California Micro Devices PAC DN027 is a transient voltage suppressor array that provides a very high level of protection for sensitive integrated circuit terminals that may be subjected to electrostatic discharge (ESD). The PAC DN027 is designed and characterized to safely dissipate ESD strikes at levels well beyond the maximum requirements set forth in the IEC 61000-4-2 specification (Level 4, 8KV contact discharge). All pins of the PAC DN027 are rated at 30KV using the IEC 61000-4-2 contact discharge method. SCHEMATIC CONFIGURATION STANDARD SPECIFICATIONS Parameter Min.
