Introduction
Although designs using the Si3018 and Si3019 comply
with UL1950 3rd Edition and pass all overcurrent and
overvoltage tests, there are still several issues to
consider.
Figure 48 shows two designs that can pass the UL1950
overvoltage tests and electromagnetic emissions. The
top schematic shows the configuration in which the
ferrite beads (FB1, FB2) are on the unprotected side of
the sidactor (RV1). For this configuration, the current
rating of the ferrite beads needs to be 6 A. However, the
higher current ferrite beads are less effective in
reducing electromagnetic emissions.

The bottom schematic of Figure 48 shows the
configuration in which the ferrite beads (FB1, FB2) are
on the protected side of the sidactor (RV1). For this
design, the ferrite beads can be rated at 200 mA.
In a cost optimized design, it is important to remember
that compliance to UL1950 does not always require
overvoltage tests. It is best to plan ahead and know
which overvoltage tests applies to your system.
System-level elements in the construction, such as fire
enclosure
considered during the design stages. Consult with your
professional testing agency during the design of the
product to determine which tests apply to your system.
