AOZ8304A Low Capacitance V TVS Diode The AOZ8304A is a transient voltage suppressor array designed to protect high speed data lines from ESD and lightning. This AOZ8304A incorporates eight surge rated, low capacitance steering diodes and a TVS in a single package. During transient conditions, the steering diodes direct the transient to either the positive side of the power supply line or to ground. The AOZ8304A may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 and IEC The TVS diodes provide effective suppression of ESD voltages ±30 kV air discharge and ±30 kV contact discharge . The AOZ8304A comes in a Halogen Free and RoHS compliant DFN-10 mm x mm package and is rated over a -40 °C to +85 °C ambient temperature range. The AOZ8304A is compatible with both lead free and SnPb assembly techniques. The small size, low capacitance and high ESD protection makes the AOZ8304A ideal for protecting high speed video and data communication interfaces. z ESD protection for high-speed data lines IEC 61000-4-2, level 4 ESD immunity test ±30 kV air discharge and ±30 kV contact discharge IEC 61000-4-4 EFT 40 A 5/50 ns IEC 61000-4-5 Lightning 25 A Human Body Model HBM ±30 kV z Small package saves board space z Low insertion loss z Protects four I/O lines z Low clamping voltage z Low operating voltage V z Green product z Pb-free device z 10/100/1000 Ethernet z USB power and data line protection z Video graphics cards z Monitors and flat panel displays z Digital Video Interface DVI z T1/E1 telecom ports TRD0+ TRD0TRD1+ TRD1Gigabit Ethernet Controller TRD2+ TRD2TRD3+ TRD3- AOZ8304A AOZ8304A RJ45 Connector 75Ω 75Ω 75Ω 75Ω Figure 10/100/1000 Ethernet Port Connection Page 1 of 8 AOZ8304A Ordering Information Part Number AOZ8304ADI Ambient Temperature Range -40 °C to +85 °C Package mm x mm DFN-10 Environmental Green Product AOS Green Products with “L” suffix use reduced levels of Halogens, and are also RoHS compliant.
