3 Description
The TPD2S017 is a two channel electrostatic
discharge (ESD) protection device. This protection
product offers two-stage ESD transient voltage
suppression (TVS) diodes in each line with a typically
1-Ω series resistor isolation. This architecture allows
the device to clamp at a very low voltage during
system level ESD strikes.
The TPD2S017 conforms to the IEC61000-4-2 ESD
protection standard. Due to the series resistor
component, the TPD2S017 provides a controlled filter
roll-off for even greater spurious EMI suppression and
signal integrity. The monolithic silicon technology
allows good matching of the component values,
including the clamp capacitances and the series
resistors between the differential signal pairs. The
tight matching of the line capacitance and series
resistors ensures that the differential signal distortion
due to added ESD clamp remains minimal, and it also
allows the part to operate at high-speed differential
data rate (in excess of 1.5 Gbps). The DBV package
offers a flow-through pin mapping for ease of board
layout.
Typical applications of this ESD protection device are
circuit protection for USB data lines, IEEE 1394
Interfaces, LVDS, MDDI/MIPI and HS signals.
