2009/ 06 / 20 ver.1 page 1 SPE6V8UH ultra low capacitance 4 -line esd protection array description applications the SPE6V8UH 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 SPE6V8UH is consists of eight low capacitance steering diodes and a tvs diode in a msop-10l package. each channel of SPE6V8UH 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 ( msop-10l ) 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 SPE6V8UH ultra low capacitance 4 -line esd protection array schematic & pin configuration application information the hdmi compliance test specification (cts) requires sink (receiver) ports maintain a differential impedance of 100 ohms +/- 15%. the measurement is taken using a time domain reflect (tdr) method that utilizes a pulse with a rise time <= 200ps.esd protection devices have an inherent junction cap acitance. even a small amount of added capacitance on an hdmi port will cause the impedance of the differential pair to drop. as such, some form of compensation to the layout will be required to bring the differential pairs back within the required 100ohm +/-15% range. the higher the added capacitance, the more extreme the modifications will need to be. if the added capacitance is too high, compensation may not even be possible. the SPE6V8UH presents <1pf capacitance between the pairs while being rated to handle >8kv esd contact discharges(>15kv ai r discharge) as outlined in iec 61000-4-2.as such, it is possible to make minor adjust ments to the board layout parameters to compensate for the added capacitance of the SPE6V8UH. as figure shows how to implement the SPE6V8UH in an hdmi application (transmitter and receiver).
