The rapid growth of data traffic whether driven by smartphones, wearables and applications such as virtual reality and the Internet of Things (IoT) is leading to increased numbers of high-speed interfaces that typically require protection against ESD events.
Theses protection diodes - DF2B5M4SL, DF2B6M4SL, DF10G5M4N and DF10G6M4N - offer protection for high-speed interfaces including USB 3.1 applications and offer a choice of operating voltages (3.6V and 5.5V) and packages (SOD962 and DFN10) providing flexible options to provide ESD protection in a variety of designs.
These four devices are able to deliver low capacitance, low dynamic resistance and high ESD endurance. Minimum signal distortion of high-speed data signals is guaranteed by the ultra-low capacitance of 0.2pF, while a typical dynamic resistance of RDYN=0.5Ω ensures low clamping voltages. High ESD protection levels are supported as electrostatic discharge voltages of at least ±20kV according to IEC61000-4-2 are guaranteed.
The DF2BxM4SL devices are suitable for mounting on high component density PCBs as the SOD-962 package requires a footprint of only 0.62 x 0.32mm and can be placed close to ICs that need ESD protection.
In the case of the DF10GxM4N types, the DFN10 package can be simply placed on top of a 4bit bus line. This flow-through design supports simple bus routing on the PCB as no additional stubs are needed to connect single TVS diodes.
