ESD devices protect at high frequency data rates
The TESD Series of ultra-low-capacitance ESD protection devices has been introduced by Taiwan Semiconductor.
The Series comprises a wide selection of SMD components, providing single and multiple, unidirectional and bidirectional versions, for I/O ports (USB 2.0, USB 3.0, HDMI), audio systems, power ports and a variety of other ESD protection applications.
The low capacitance topology of the TESD Series provides protection at high frequency data rates while maintaining signal integrity.
In I/O port applications, TESD Series devices meet regulatory requirements including repetitive application of IEC61000-4-2 (ESD) ±15kV (air), ±10kV (contact) and IEC61000-4-5 (Lightning): 5.5A (8/20μs). These devices also meet 30 KV contact/air requirements for power port applications.
In addition, the Series meets all global environmental requirements.
The devices’ ultra-low capacitance is essential for ±3.3V or other nominal operating voltage applications operating at high data rates. The ESD protection devices ideally have little to no effect on normal operation while retaining the ability to survive repeated application of ESD discharges.
“By using these high-performance protection devices, the ESD is absorbed and safely clamped– dissipated through the TVS diodes – preventing expensive damage and increasing the reliability and survivability of the end equipment,” said Sam Wang, Vice President, TSC Products. “This is achieved while also providing margin on protection and signal integrity.”
