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.

Parameter Definitions
Operation Voltage (VDC)
Defined as DC voltage, under which device is in OFF state and leakage current below certain threshold.
Leakage Current (IL)
Current through device under Operation Voltage VDC.
Trigger Voltage (VT)
Voltage at which the device switches from the OFF to the ON state, during the IEC waveform or the TLP system.
Clamping Voltage (VC)
Voltage cross device under 8kV per IEC or measured by TLP system. Typically measured 30ns after initiation of the ESD pulse
(for TLP, both 30ns and 60ns are sometimes used).
Capacitance (CP)
Capacitance of the device measured at 1MHz with 0V and max operating voltage bias.
