description
These devices are primary protector components for semiconductor arrester assemblies intended to meet the
generic requirements of Bellcore GR-974-CORE (November 1994) or ITU-T Recommendation K28 (03/93).
To conform to the specified environmental requirements, the 2ELx must be installed in a housing which
maintains a stable microclimate during these tests (e.g. FIGURE I.1/K28).
The protector consists of a symmetrical voltage-triggered bidirectional thyristor. Overvoltages are initially
clipped by breakdown clamping until the voltage rises to the breakover level, which causes the device to
crowbar into a low-voltage on state. This low-voltage on state causes the current resulting from the
overvoltage to be safely diverted through the device. The high crowbar holding current prevents d.c. latchup
as the diverted current subsides. This 2ELx range consists of three voltage variants to meet various
maximum system voltage levels. They are guaranteed to voltage limit and withstand the listed international
lightning surges in both polarities.
These monolithic protection devices are constructed using two nickel plated copper electrodes soldered to
each side of the silicon chip. This packaging approach allows heat to be removed from both sides of the
silicon, resulting in the doubling of the devices thermal capacity, enabling a power line cross current capability
of 10 A rms for 1 second. One of the 2ELx’s copper electrodes is specially shaped to promote a progressive
shorting action (at 50/60 Hz currents greater than 60 A). The assembly must hold the 2ELx in compression,
so that the cell electrodes can be forced together during overstress testing. Under excessive power line cross
conditions the 2ELx will fail short circuit, providing maximum protection to the equipment.
