2009/ 06 / 20 ver.1 page 1 SPE6V8UD ultra low capacitance 4 -line esd protection array description applications the SPE6V8UD is 4-channel very low capacitance esd transient voltage suppressor which provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge. it is particularly well-suited to protect systems with high speed communication lines from esd, eft, and lighting. the SPE6V8UD is consists of eight low capacitance steering diodes and a tvs diode in a slp package. each channel of SPE6V8UD could safely dissipate esd strikes of 15kv air discharge as well as 8kv contact discharge, meeting the requirement of the iec 61000-4-2 international standard. using the mil-std-883 (method 3015) specification for human body model (hbm) esd, the device provides protection for contact discharges to greater than 15kv. ? cellular handsets and accessories ? cordless phone ? pda ? notebooks and handhelds ? portable instrumentation ? digital cameras ? mp3 player high definition multi-media interface protection ? usb 2.0 power and data line ? monitors and notebook computers ? hdsl, idsl secondary ic side protection ? 10/100/1000 ethernet features pin configuration ( dfn-10 ) ( length = 2.5mm ) part marking ? transient protection for data lines to iec 61000-4-2 (esd) 15kv (air) 8kv (contact) iec 61000-4-4 (eft) 40a (5/50ns) ? protects five bidirectional i/o lines ? working voltage: 5v ? low leakage current ? low operating and clamping voltages ? low capacitance: 0.35 pf typical

2009/ 06 / 20 ver.1 page 4 SPE6V8UD ultra low capacitance 4 -line esd protection array schematic & pin configuration as figure shown is an example of how to route the high speed differential trac es through the SPE6V8UD.the solid line represents the pcb trace. the p cb traces are used to connect the pin pa irs for each line (pin 1 to pin 10, pin 2 to pin 9, pin 4 to pin 7, pin 5 to pin 6). for example, line 1 enters at pin 1 and exits at pin 10 and the pcb trace connects pin 1 and 10 together. this is true for lines connected at pins2, 4, and 5 also. ground is connected at pins3 and 8. one large ground pad should be used in lieu of two separate pads. application information ( design recommendations for hdmi protection ) adding external esd protection to hdmi ports can be cha llenging. first, esd protection devices have an inherent junction capacitance. however, adding even a small amount of capacitance will cause the impedance of the differential pair to drop. second , large packages and la nd pattern requirements cause discontinuities that adversely affect signal integrity. the SPE6V8UD and is specifically designed for protection of high-speed interfaces such as hdmi. they present <0.4pf capacitance between the pa irs while being rated to handle +/-8kv esd contact discharges (15kvair discharge) as outlined in iec61000-4-2. each device is in a leadless dfn package that is less than 1.1mm wide. they are designed such that the traces flow straight through the device. the narrow package and flow-through design reduces discontinuities and minimizes im pact on signal integrity. this becomes even more critical as signal speeds increase. flow through layout using SPE6V8UD
