USBULC6-2F7

2-line Transil™ ultralow capacitance protection for high speed USB

Datasheet

Features

 Ultralow capacitance (1pF)

 Two data lines (D+ and D-) protected against

ESD

 Breakdown voltage V

 Flip Chip 350 µm pitch, lead-free

 Very low leakage current

 Very small PCB area

 RoHS compliant

Benefits

 Minimized impact on rise and fall times for

maximum data integrity

 Low PCB space occupation

 Higher reliability offered by monolithic

integration

Complies with the following standards

 IEC 61000-4-2 level 4:

– ±8 kV (contact discharge)

 MIL STD 883G - Method 3015.7

– ±25 kV (Human body model)

Application

This device is designed to protect a high speed

USB port in wireless handsets (up to 480 Mb/s

according to USB 2.0 high speed specification).

Description

The USBULC6-2F7 is a monolithic, application

specific discrete device dedicated to ESD

protection of high speed interfaces.

Its ultra low line capacitance secures a high level

of signal integrity without compromising the

protection of downstream sensitive chips against

the most stringently characterized ESD strikes.
