DESCRIPTION
Defined product set SB and SC families are
a series of Thyristor surge suppression
(TSS) devices designed to protect
telecommunication equipment against
lightning. These devices can be used on
central office equipment, PBX, DSU, OCU,
digital telephones, fax machines, modems
and radio controlled equipment. The
bidirectional configuration provides
protection for both positive and negative
transients and the discrete surface mount
package allows individual placement of the
device on line cards or other locations where
multiple component devices do not offer the
versatile in board trace layout.
The ProTek TSS device can be used to
provide protection in accordance with
industry standard requirements, such as
FCC Part 68, ANSI C62.41, UL 1459 and
GR-1089-CORE. Their low capacitance is
ideal for T1/E1 trunk or line card applications.

Application Notes for Thyristor Surge Suppressors
used in Telecommunication Circuits
®
4
The TSS device is located across the tip-to-ring line after a limiting
resistor and fuse combination. RTIP and RRING resistors are optional
depending upon the TSS device selection. Without the resistors, the
PP3100SB/SC is recommended. However, with a resistance value of
7.5 ohms for tip and ring, the PP3100SA is recommended. Digital
signals may use a lower TSS device depending upon the total tip to
ring voltage range. Selection of the TSS device, either PPxxxxSB or
PPxxxxSC is based upon the value of the tip and ring resistors. For
the National Electronic Code (NEC) article 800, it is recommended
that at least one fuse be used in the tip or ring line for metallic surges.
Fuses may be replaced with a suitable Positive Temperature Coeffi-
cient (PTC) automatic resettable current limiting device.

There are two TSS devices, one located from tip-to-ground and one ring-
to-ground. The PP3100SB/SC is recommended for resistor values of 7.5
ohms each. The National Electric Code (NEC) article 800 requires two
fuse elements when connecting to ground. Fuses or a suitable Positive
Temperature Coefficient (PTC) automatic resettable current limiting
device may be used. The purpose of this circuit is to limit AC power
current from getting on the ground line causing any safety hazard.

Three equal TSS devices are used in this application for metallic (tip-
to-ring) and longitudinal (tip-to-ground and ring-to-ground) protection.
For analog signals, the PP3100SB/SC is recommended. The Na-
tional Electric Code (NEC) article 800 requires two fuse elements
when connecting to ground. Fuses or a suitable Positive Temperature
Coefficient (PTC) automatic resettable current limiting device may be
used. This is circuit is recommended for protection against the
Bellcore requirement: First Level Lightning Surge Tests (Telecommu-
nications Port), document # GR-1089-CORE.
