systems such as cell phones or laptop computers it is not
clearly defined in the spec how to specify a clamping voltage
at the device level. ON Semiconductor has developed a way
to examine the entire voltage waveform across the ESD
protection diode over the time domain of an ESD pulse in the
form of an oscilloscope screenshot, which can be found on
the datasheets for all ESD protection diodes. For more
information on how ON Semiconductor creates these
screenshots and how to interpret them please refer to
AND8307/D.
ESD Voltage Clamping
For sensitive circuit elements it is important to limit the
voltage that an IC will be exposed to during an ESD event
to as low a voltage as possible. The ESD clamping voltage
is the voltage drop across the ESD protection diode during
an ESD event per the IEC61000−4−2 waveform. Since the
IEC61000−4−2 was written as a pass/fail spec for larger

Figure 10. Negative TLP I−V Curve
TLP parameter: Z0 = 50 W, tp = 100 ns, tr = 300 ps, averaging window: t1 = 30 ns to t2 = 60 ns. VIEC is the equivalent voltage
stress level calculated at the secondary peak of the IEC 61000−4−2 waveform at t = 30 ns with 2 A/kV. See TLP description
below for more information.
Transmission Line Pulse (TLP) Measurement
L
Transmission Line Pulse (TLP) provides current versus
voltage (I−V) curves in which each data point is obtained
from a 100 ns long rectangular pulse from a charged
transmission line. A simplified schematic of a typical TLP
system is shown in Figure 11. TLP I−V curves of ESD
protection devices accurately demonstrate the product’s
ESD capability because the 10s of amps current levels and
under 100 ns time scale match those of an ESD event. This
is illustrated in Figure 12 where an 8 kV IEC 61000−4−2
current waveform is compared with TLP current pulses at
8 A and 16 A. A TLP I−V curve shows the voltage at which
the device turns on as well as how well the device clamps
voltage over a range of current levels. For more information
on TLP measurements and how to interpret them please
refer to AND9007/D.

current region in order to better protect the sensitive low
voltage, high−speed TMDS signals. The I/O pins for lower
speed lines have a higher breakdown voltage to
accommodate the higher voltages associated with the HPD,
CEC, I2C and VCC lines as well as the optional Ethernet pin
that can be implemented in HDMI1.4/2.0 applications.
I/O pins 1, 2, 4, 5, 7, 8, 10, and 11 are to be used for high
speed differential TMDS lines whereas I/O pins 3, 6, 9, 13,
15, and 17 are to be used for lower speed lines (I2C, CEC,
HPD, etc.). The ESD8040 was designed specifically for the
HDMI application. The I/O pins for TMDS lines have a
lower breakdown voltage and faster turn−on in the low

ESD Protection Device Technology
• Low voltage punch through (LVPT): The key
advatange for this technology is a very low turn-on
voltage as shown in Figure 19. This technology
provides optimized protection for chipsets with small
geometries against recoverable failures due to voltage
peaks (also known as “soft failures”).
