SPE6V8UD

SPE6V8UD Ultra Low Capacitance 4 -Line ESD Protection Array DESCRIPTION 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.

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 SPE6V8UD 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 SPE6V8UD and is specifically designed for protection of high-speed interfaces such as HDMI. They present
