The VBUS051BD-HD1 from Vishay Semiconductors is an
ESD, single line protection diode providing 0.9pF typical and
1.3pF maximum capacitance in the new LLP1006 package;
its 0.6mm by 1.0mm footprint and ultra-low profile of
0.38mm saves board space. It is highly suited to ESD
protection of portable electronics in mobile computing,
mobile communication, consumer, industrial and medical
applications.
The VBUS051BD-HD1 provides transient protection for one data
line at ±15kV contact discharge in compliance with IEC 61000-4-2
(ESD) and for a peak pulse current of 3A (t
p
=8/20µs) in accordance
with IEC 61000-4-5 (surge immunity). Its new, compact LLP package
uses an environmentally friendly ‘green’ moulding compound and
it features a low maximum leakage current of 0.1µA at 5V and a
maximum clamping voltage of 15V at 3A. Breakthrough voltage
ratings are 8.7V (maximum) and 7.9V (typical) at 1mA. The diode is
compliant with RoHS 2002/95/EC and WEEE 2002/96/EC.
VBUS051BD-HD1 Electrical Characteristics
Two quad ESD diode-protection arrays feature low capacitance of
6.5pF and 12pF and maximum working ranges of 5V and 9V in
an LLP1010-5L package; its 1mm by 1mm footprint and 0.4mm
profile offers board space savings.
The small size of the VESD05A4A-HS4 and VESD09A4A-HS4
diode-protection arrays provides four-line ESD data-port protection
suitable for space-limited mobile electronics, such as portable
gaming systems, MP3 players and mobile phones. The devices offer
different maximum working range, load capacitance, surge current
and low typical leakage current (see table). Both diodes provide
transient protection for four data lines as per IEC 61000-4-2 (ESD)
at ±15kV (contact discharge) and ±20kV (air discharge) and are
compliant with RoHS 2002/95/EC and WEEE 2002/96/EC.
