Typical Application


SYT01A03 is an ultra-low capacitance Transient Voltage Suppressor (TVS) designed to provide electrostatic discharge (ESD) protection for high-speed data interfaces. With typical capacitance of 0.15pF only, SYT01A03 is designed to protect parasitic-sensitive systems against over-voltage and over-current transient events. It complies with IEC61000-4-2(ESD)(±15kV air, ±15kV contact discharge), IEC61000-4-5(Surge)(4A, 8/20μs)etc.


SYT01A03 uses ultra-small DFN0.6*0.3-2L package. Each SYT01A03 device can protect one high-speed data line. The combined features of ultra-low capacitance, ultra-small size and high ESD robustness make SYT01A03 ideal for high-speed data ports and high-frequency lines (e.g., HDMI & DVI) applications. The low clamping voltage of the SYT01A03 guarantees a minimum stress on the protected IC.
