Description
Ordering Information
The PolySurg™ 0603ESDA-TR1 ESD Suppressors protect valuable high-
speed data circuits from ESD damage without distorting data signals as a
result of its ultra-low (0.15pF maximum) capacitance.
Features
Catalog Number Description
• 0603/1608 footprint surface mount device
• Ideal ESD protection for high frequency, low voltage applications.
• Provides ESD protection with fast response time (<1ns) allowing
equipment to pass IEC 61000-4-2 testing
• Very low leakage current

Device Marking
PolySurg™ ESD Suppressors are marked on the tape and reel
packages, not individually. Since the product is bi-directional and
symmetrical, no orientation marking is required.

The location in the circuit for the TR1 series has to be carefully
determined. For better performance, the device should be placed
as close to the signal input as possible and ahead of any other
component. Due to the high current associated with an ESD
event, it is recommended to use a “0-stub” pad design (pad
directly on the signal/data line and second pad directly on com-
mon ground).

The TR series currently has a convex profile on the top surface of
the part. This profile is a result of the construction of the deice.
They can be processed using standard pick-and-place
equipment. The placement and processing techniques for these
devices are similar to those used for chip resistors and chip
capacitors.
1. Some shifting in characteristics may occur when tested over several hundred ESD pulses at
very rapid rate of 1 pulse per second or faster.
2. Per IEC 61000-4-2, 30A @ 8kV, level 4, clamp measurement made 30ns after initiation of
pulse, all tests in contact discharge mode.
3. Trigger measurement made using Transmission Line Pulse (TLP) method.
4. PolySURG™ devices are capable of withstanding up to a 15kV, 45A ESD pulse. Device ratings
are given at 8kV per Note 1, unless otherwise specified.
