Ultra-Low Capacitance ESD
Protection
Micro−Packaged Diodes for ESD Protection
The ESD7461 is designed to protect voltage sensitive components
that require ultra−low capacitance from ESD and transient voltage
events. It has industry leading capacitance linearity over voltage
making it ideal for RF applications. This capacitance linearity
combined with the extremely small package and low insertion loss
makes this part well suited for use in antenna line applications for
wireless handsets and terminals.

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
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 9. 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 10 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.
