DESCRIPTION
KEY FEATURES
The “FemtoFarad” product family is specifically for ESD bidirectional protection of
vulnerable electronic components, especially at IO ports. Continued shrinking of on-
chip component geometries of sub-micron sizes have reduced levels of ESD at which
upset and failure occurs to the extent that protection is mandatory for reliability of
power and data line interfaces. The sub-picofarad capacitance of this series provides
excellent performance up through six GHz with minimal attenuation without linear
or harmonic distortion well into the GHz range. In the off-state, this FemtoFarad,
polymeric based technology is virtually invisible to circuit performance. Its proven
structure is thick film on a rugged ceramic base that is ideal for automated assembly.
Subsequent paragraphs and charts describe the outstanding performance and
reliability of FemtoFarad components and many other features that make them the
designer’s choice for ESD protection.

Notes:
1. Continuous operation with 12 volts or more under extreme temperature and humidity may cause increasing leakage current and/or shifting
device resistance. However, even under severe environmental test, characteristics of the device did not change up to 6 V dc operation.
2. Some shifting in characteristics may occur when tested over several hundred ESD pulses at very rapid rate of 1 pulse per second or faster.
3. Per IEC 61000-4-2, 30 A @ 8 kV, level 4, clamp measurement made 30 ns after initiation of pulse, all tests in contact discharge mode.
4. Trigger measurement made using Transmission Line Pulse (TLP) method.
5. FemtoFarad 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.
