Low capacitance, low clamping voltage ESD suppression devices
1 min read
ON Semiconductor has introduced five new ESD suppression devices. The ESD8000 modules are said to deliver the industry's lowest capacitance and ESD clamping voltage, making them suitable for use with extremely high data rate interfaces and small geometry chipsets.
The devices achieve maximum capacitance specification of 0.35pF, and ESD clamping voltages down to 8V at 16A, equivalent to IEC61000-4-2 Level 48kV contact.
ON says the low capacitance virtually eliminates any degradation to the data line signal integrity at data rates greater than 10Gb/s, supporting emerging interfaces such as USB 3.0, USB 3.1, HDMI 2.0 and Thunderbolt. The low clamping voltage is said to improve protection of system level ESD testing as chipsets evolve into geometries below 20nm, making them more sensitive to transient voltage.
The four-line ESD8004 and ESD8104 can protect two pairs of voltage sensitive high speed data lines in the industry standard footprint of the 2.5 x 1mm UDFN-10 package, making them suitable for the latest serial interface standards such as USB 3.0, HDMI 2.0, and eSATA.
The flow-through style package enables easy printed circuit board layout and the matched trace lengths necessary to maintain consistent impedance between high speed differential lines.
