• Exceeds testing requirements outlined in IEC
• Extremely low capacitance
• Very low leakage current
• Fast response time
• Surface mount
• Solder termination
• RoHS compliant
ESDA devices are marked on the tape and reel
packages, not individually. Since the product is bi-
directional and symmetrical, no orientation marking is
ESDA family are applicable to most signal line circuits. It is applied
in a shunt-connected manner. They are not suitable for use on
lines where lighting or load-switching transients are present.
ESDA family is ideal for use in computers and computer-related
equip-ment, such as modems, keyboards, and printers. ESDA
family is also well suited for portable electronic equipment such
as mobile telephones, test equipment, and card scanners.
ESDA family currently have a convex profile on the top surface of
the part. This profile is a result of the construction of the device.
They can be processed using standard pick – and – place
equipment. The placement and processing techniques for ESDA
family are similar to those used for chip resistors and chip
The Location in the circuit for the ESDA family has to be carefully
determined. For the better performance of the device, the device
should be positioned as close to the signal input as possible and
ahead of any other component.

1. The product is 100% tested for 30V operating voltage at 25°C.
Continuous operation with higher than 12VDC under extreme
temperature and humidity may cause increasing leakage cur-
rent and/or shifting device resistance. However, even under
severe environmental test, characteristics of the device did not
change up to 12VDC 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, 30A @ 8kV, level 4, clamp measurement
made 30 ns after initiation of pulse, all tests in contact dis-
4. Trigger measurement made using Transmission Line Pulse
5. PolySurg™ devices are capable of withstanding up to a 15 kV,
45A ESD pulse. Device ratings are given at 8kV per Note 1,
unless otherwise speci ed.
