Infineon Extends Circuit Protection Portfolio with Low Dynamic Resistance and Ultra-Low Capacitance TVS Devices for High-Speed Data Interfaces
Infineon introduced a series of Transient Voltage Suppression devices offering best-in-class protection against Electrostatic Discharge for electronic systems. With very-low dynamic resistance and ultra-low capacitance the ESD102 TVS Diode enable engineers to achieve strict requirements for ESD robustness and signal quality of the high-speed interfaces used in the latest generation smartphones and tablets.
ContThe ESD102 series addresses TVS for the high-speed data interfaces – such as USB 3.0, GBit Ethernet, Firewire and HDMI links - used in desktop laptops, computers, consumer electronics and also in more and more smartphones. These data lines require robust protection with the smallest possible package size and lowest device capacitance. The new series provides protection that exceeds specifications of IEC61000-4-2, in either a 2-pin (for single line), 4-pin (for 2-line array) or 5-pin (for 4-line array) package. Leakage current is ≤ 50nA, contributing to longer system battery life. A dedicated pad layout keeps PCB layout simple and minimizes parasitic effects.
