AOZ8934 Ultra-Low Capacitance TVS Diode General Description Features The AOZ8934 is a transient voltage suppressor array designed to protect high speed data lines. It is specially designed to protect portable devices that utilize the USB port for battery charging. Array of surge rated diodes with internal TVS diode ESD protection for high-speed data lines: This device incorporates three 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. It provides a typical line-to-line capacitance of 0.3 pF and low insertion loss up to 6 GHz providing greater signal integrity making it ideally suited for USB 2.0 applications. An integrated 26V TVS diode is used for protection of the USB voltage bus. The AOZ8934 comes in a RoHS compliant SOT23-6 package and is rated for -40 °C to +125 °C junction temperature range. – IEC 61000-4-2, level 4 (ESD) immunity test Air discharge: ±20 kV; contact discharge: ±15 kV – IEC61000-4-4 (EFT) 40 A (5/50 ns) – IEC61000-4-5 (Lightning) 4 A (8/20 µs) – Human Body Model (HBM) ±24 kV Low capacitance between I/O lines Low clamping voltage on D+, D- and ID pins Protects USB VBus operating up to 26 V – IEC61000-4-2, level 4 (ESD) immunity test Air discharge: ±30 kV; contact discharge: ±30 kV – IEC61000-4-5 (Lightning) 30 A (8/20 µs) Small package saves board space Applications USB 2.0 USB OTG Typical Application VBus Mini USB DD+ ID GND D- 2 NC GND 3 1 5V 26V 4 5 D+ 6 VBus ID AOZ8934CI-26 Rev. 2.0 October 2014 www.aosmd.com Page 1 of 7 AOZ8934 Ordering Information Part Number Ambient Temperature Range Package Environmental AOZ8934CI-26 -40 °C to +85 °C SOT23-6 RoHS Compliant Green Product AOS Green Products use reduced levels of Halogens, and are also RoHS compliant.
