PESD PROTECTION DEVICES
Littelfuse’s Polymer ESD (PESD) line of devices helps
protect I/O ports on HDMI 1.3, portable video players,
LCD and plasma TVs, USB 2.0, digital visual interface
(DVI)
and
antenna
switches.
PESD
devices
shunt
electrostatic discharge away from sensitive circuitry in
HDTV equipment, printers, laptops, cellular phones and
other portable devices.
PESD devices offer many advantages over traditional
protection devices, such as multi layer varistors (MLVs),
which may degrade or distort the signal in high data
rate circuits. Compared to miniature gas discharge tubes
(GDTs), PESD devices provide a more compact form factor
and an economical solution for the shrinking profiles of
today’s compact information appliances.
Available in a range of form factors, our PESD protection
devices provide low capacitance and meet transmission
line pulse (TLP) testing, as well as IEC61000-4-2 testing.
BENEFITS
• ESD protection for high frequency application
(HDMI 1.3)
• Smaller form factor for board space savings
• Helps protect sensitive electronic circuits against
damage caused by electrostatic discharge (ESD)
events
• Assists equipment to pass IEC 61000-4-2,
level 4 testing
APPLICATIONS
• HDMI 1.3 interfaces
• LCD & plasma TVs
• Cellular phones
• Antennas
• Portable video players
• Portable devices (PDA, DSC, Bluetooth)
• Printer ports
• Satellite radios
• USB 2.0 and IEEE 1394 interfaces
• DVI
• GPS systems
FEATURES
• RoHS compliant
• Lead free
• Halogen free
(refers to: Br
≥
900ppm, Cl
≥
900ppm, Br+Cl
≥
1500ppm)
• 0.25 pF (typ) capacitance
• Low-leakage current
• Low-clamping voltage
• Fast response time (< 1ns)
• Capable of withstanding numerous ESD strikes
• Compatible with standard reflow installation
procedures
