Leiditech’ ESD line of devices help protect I/O
• ESD protection for high frequency applications
(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
• RoHS compliant
• Halogen free
(refers to: Brⱕ900ppm, Clⱕ900ppm, Br+Clⱕ1500ppm)
•50pF (typical)capacitance
• Low-leakage current
• Low-clamping voltage
• Fast response time (< 1ns)
• Capable o
f wi
thstanding numerous ESD strikes
• Compatible with standard reflow installation
procedures
• Thick film technology
• Bi-directional protection
• HDMI 1.3 interfaces
• LCD & plasma TV
• Cellular phones
• Antennas
• Portable video players
• Portable devices (PDA, DSC, BlueTooth)
Benefits Features
Applications
• Printer ports
• Satellite radios
• USB 2.0 and IEEE 1394 interfaces
• DVI
• GPS systems
ports on HDMI 1.3, portable video players, LCD & plasma
TVs, USB 2.0, digital visual interface (DVI), and antenna
switches. ESD devices shunt electrostatic discharge
away from sensitive circuitry in HDTV equipment,
printers, laptops, cellular phones, and other portable
devices.
ESD devices offer many advantages over traditiona
l
prote
ction devices, such as multi layer varistors (MLVs),
which may degrade or distort the signal in high data rate
circuits. Compared to transient voltage suppression
(TVS) diodes and miniature gas discharge tubes (GDTs),
ESD 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 ESD protection
devices provide low capacitance, and meet tra
nsmission
line pulse (TLP) testing, as well as IEC61000-4-2 testing.

Notes:
1. Trigger and clamping voltage are meas ured per IEC 61000-4-2, 8KV contact discharge method.
2. After reliability tests such as high Temp storage, Temp cycles, continuous ESD strike etc, the
maximum leakage current is less than 1uA.
