USBULC6-2F4

2-line, ultralow capacitance protection in 0.3 mm pitch

Datasheet

Features

 Ultralow capacitance diode (1.5 pF max)

 0.3 mm pitch

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

ESD

 Flip Chip, 300 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:

– ±15 kV (air discharge)

– ±8 kV (contact discharge)

Description

The USBULC6-2F4 is a monolithic, application

specific discrete device dedicated to ESD

protection of high speed interfaces.

Its ultralow line capacitance secures a high level

of signal integrity without compromising the

protection of downstream sensitive chips against

the most stringently characterized ESD strikes.
