DESCRIPTION
The UTC UESD4CUSB30 is 4 channel Transient Voltage
Suppressor (TVS) based Electrostatic Discharge (ESD) protection
diode arrays. The UTC UESD4CUSB30 device is rated to
dissipate ESD strikes at the maximum level specified in the IEC
61000-4-2 international standard (Contact). These devices also
offer 5A (8/20μs) peak pulse current ratings per IEC 61000-4-5
(Surge) specification.

FEATURES
* Supports USB 3.0 Data Rates (5 Gbps)
* Low Capacitance
* IEC 61000-4-2 ESD Protection (Level 4 Contact)
* IEC 61000-4-5 Surge Protection -5A (8/20µs)
* Dynamic Resistance: 0.6Ω (Typ)
* Flow-Through Pin Mapping
