UAE6V8UD Ultra Low Capacitance 4-Channel ESD Protection Array General Description Features The UAE6V8UD 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 UAE6V8UD is consists of eight low capacitance steering diodes and a TVS diode in a SLP package. Each channel of AFEA6V8UD 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.

The PCB traces are used to connect the pin pairs 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. Flow through Layout Using AFE6V8UD Application Information ( Design Recommendations for HDMI Protection ) Adding external ESD protection to HDMI ports can be challenging. 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 land pattern requirements cause discontinuities that adversely affect signal integrity. The AFE6V8UD and is specifically designed for protection of high-speed interfaces such as HDMI. They present <0.4pF capacitance between the pairs 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 impact on signal integrity. This becomes even more critical as signal speeds increase. – 60 – UAE6V8UD Ultra Low Capacitance 4-Channel ESD Protection Array DFN-10 PACKAGE OUTLINE – 61 –
