2 channel 5.5-V, 1-pF, ±11kV ESD protection diode with low clamping and EMI filtering

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.
