compact unit which provides lightning and electromagnetic pulse
(EMP) protection of systems in which many signal lines enter
sensitive electronic equipment. The efficient packaging of the
ESA circumvents the concept of one protective device per line. It
provides a surge arrestor which has the advantage of space sav-
ing and simplified assembly when compared to current protective
devices which range from diodes to large spark gaps.
Amphenol Transient Protection
ESA – Energy Shunting Assembly
The Amphenol
The current ESA design consists of two 53-pin contact, Mil-Stan-
dard, hermetic connectors assembled back to back, and encom-
passing a ground plate. A sealed chamber is formed within this
thru-bulkhead unit, housing 53 in-line spark gaps. Introducing a
controlled atmosphere enhances fast rise breakdown.
The ESA can be integrated with an EMI filter connector which
can improve its performance. These two assemblies provide a
method to help protect against lightning, EMP, EMI and TEM-
PEST effects.

Energy Shunting Assembly (ESA) is a simple,
1. DC breakdown voltage
2. Maximum rated surge discharge current (8 x 20 microsecond pulse)
3. Insulation resistance
4. Capacitance between each electrode and the ground plane
5. Rate-of-rise breakdown voltage
6. Surge breakdown unbalance (at 100 Volts/microseconds)
7. Surge life (500 Ampere – 10 x 1,000 microsecond)
8. Hold-over voltage
9. Arcing voltage
10. Glow to arc transition point
11. Temperature range
