The Leiditech ULC0568KQ is an integrated USB 3.0 electrostatic protection diode that can provide ESD protection by inserting one ULC0568KQ into USB 3.0. ULC0568K can be an ideal domestic alternative for the following brands: Amazing (AZ1065-06F, Brands such as AZ1165-06F, Bourns (CDDFN10-0506N), AOS (AOZ8936DI, AOZ8937DI), ULC0568KQ are fully PIN TO PIN compatible with these models.
1. ULC0568KQ pin definition and packaging
The packaging is DFN4120 (4.1 × 2.0 × 0.55mm), and DFN packaging helps to reduce small capacitance and connect well with data lines, reducing lead inductance.
The definition of pins also takes into account the convenience of PCB wiring. You can refer to the diagram below to make differential distribution lines, and the routing is relatively smooth.
2. Application
USB 3.0 interface ESD protection
HDMI 1.4/2.0 interface ESD protection
Various high-speed data interface protections (SATA, DVI, PCI, DVI)
3. Performance parameters
Low junction capacitance: typical value 0.3PF
Ground drain current, measured current 500nA
l Vrwm=5V
IEC 61000-4-2 (ESD): Air ± 25kV, Contact ± 20kV
l – IEC61000-4-5 (8/20μs) ： 4A
4. Application of USB 3.0 Solution
Advantages of the solution: USB 3.0 provides a transmission speed of 5.0Gbps. This solution adopts single device protection, saves space, ensures signal integrity, and is equipped with a common mode inductor to filter out common mode interference. It meets IEC61000-4-2, level 4, with a contact discharge of 25kV and an air discharge of 20kV
