rev. 1.8 june 2009 www.aosmd.com page 1 of 7 AOZ8205 five-line tvs diode array general description the AOZ8205 is a transient voltage suppressor diode array designed to protect data lines from high transient conditions and esd. this state-of-the-art device utilizes a os leading edge trench vertical structure [tvs] 2 technology for superior clamping performance. this device incorporates ve tvs diodes in a single package. due to the ?xibility of the design, the package can be con?ured as a four channel bidirectional tvs array. during transient conditions, the tvs diodes direct the transient to ground. they may be used to meet the esd immunity requirements of iec 61000-4-2, level 4 (?5kv air, ?kv contact discharge). the AOZ8205 comes in an rohs compliant sc-89 package and is rated over a -40? to +85? ambient temperature range. the very small 1.7 x 1.7 x 0.6mm sc-89 package makes it ideal for applications where pcb space is a premium. the small size and high esd protection makes it ideal for protecting high speed video and data communication interfaces. features esd protection for high-speed data lines: exceeds: iec 61000-4-2 (esd) ?0kv (air), ?0kv (contact) human body model (hbm) ?0kv t rench vertical structure [tvs] 2 based technology used to achieve excellent esd clamping performance small package saves board space low insertion loss protects ?e unidirectional or four bidirectional i/o lines low clamping voltage low operating voltage: 5.0v green product, pb-free applications po r table handheld devices keypads, data lines notebook computers digital cameras por table gps mp3 players t ypical applications pin con?uration i/o1 i/o2 i/o3 i/o4 i/o5 i/o1 i/o2 i/o3 i/o4 1 2 3 6 5 4 top view unidirection protection of five lines bidirection protection of four lines 1 2 3 6 5 4
