ESD Protection Diodes
Micro−Packaged Diodes for ESD Protection
The ESD7421 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, automotive sensors, infotainment, MP3 players, digital
cameras and many other applications where board space comes at a
premium.

Transmission Line Pulse (TLP) Measurement
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 8. 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 9 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.
