ESD5481
ESD Protection Diodes
Micro−Packaged Diodes for ESD Protection
The ESD5481 is designed to protect voltage sensitive components
from ESD. Excellent clamping capability, low leakage, and fast
response time provide best in class protection on designs that are
exposed to ESD. Because of its small size, it is suited for use in cellular
phones, MP3 players, digital cameras and many other portable
applications where board space comes at a premium.

for ESD Devices.
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

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 7. 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 8 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.
