TVSF0805
“FemtoFarad” Polymer ESD Suppressor
PRODUCT PREVIEW
DESCRIPTION
The “FemtoFarad” product family is
specifically designed to protect sensitive
electronic circuits from the threat of
electrostatic discharge (ESD).
“FemtoFarad” products react almost
instantly to the transient voltage and
effectively clamp it below 60 V,
meaning less voltage stress during the
clamp period and greater IC protection.
The design of “FemtoFarad” products
inherently produces a low capacitance
part. In the off-state “FemtoFarad” is
virtually invisible to the circuit. Installed
from signal line to ground, the
“FemtoFarad” device exhibits a high
impedance and low capacitance that
makes it transparent to high-speed
digital circuits. Signals are not distorted
or disrupted.
With “FemtoFarad” devices,
waveform definition stays true and high-
speed signals do not suffer.
“FemtoFarad” products utilize a unique
polymer-based material. The nature of
the material creates a Bidirectional part,
which means that only one device is
required to provide complete ESD
protection regardless of the surge
polarity. The combination of this material
with proven thick film on ceramic
technology produces a reliable, surface
mount product that will help protect
mobile communications, computers, data
processing, test equipment, and many
other electronic applications from ESD.

Notes:
1. Per IEC 1000-4-2, 30A @ 8kV, level
4, clamping measurements made 30 ns
after initiation of pulse, all tests in
contact discharge mode.
2. Trigger measurement made using
TLP method (see page5).
3. Parts will remain within the
specifications listed in the above table
through a minimum of 20 ESD pulses.
4. TVSF0805 devices are capable of
withstanding up to a 15 kV, 45 A ESD
pulse. Device ratings are given at 8 kV
per Note 1 unless otherwise specified.
