LCAS RING AND TIP PROTECTION PAIRS
BIDIRECTIONAL THYRISTOR OVERVOLTAGE PROTECTORS
Description
Customized Voltage for LCAS Protection
Battery-Backed Ringing ............................................. 87 V rms
Ground-Backed Ringing ........................................... 101 V rms
Low Differential Capacitance ................................. 39 pF max.
.................................................... UL Recognized Components
Rated for International Surge Wave Shapes
These protector pairs have been formulated to limit the peak voltages on the line terminals of the `7581/2/3 LCAS (Line Card Access Switches)
type devices. An LCAS may also be referred to as a Solid State Relay, SSR, i.e. a replacement of the conventional electro-mechanical relay.
Overvoltages are normally caused by a.c. power system or lightning flash disturbances which are induced or conducted on to the telephone
line. These overvoltages are initially clipped by protector 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. For negative surges, the high crowbar holding current prevents d.c. latchup with the SLIC current, as the surge current
subsides.
Each protector consists of a symmetrical voltage-triggered bidirectional thyristor. They are guaranteed to voltage limit and withstand the listed
international lightning surges in both polarities.

TISP4xxxH3/M3BJ Series for LCAS Protection
APPLICATIONS INFORMATION
Introduction
These protector pairs have been designed to limit the peak voltages on the line terminals of `7581/7582/7583 LCAS (Line Card Access Switch)
parts. An LCAS may also be referred to as a Solid-State Relay, SSR, i.e. a replacement of the conventional electro-mechanical relay.
The `7581 LCAS has two solid-state switches which connect the telephone line to the line card SLIC (Subscriber Line Interface Circuit), Figure
12, SW1 and SW2. A further two solid-state switches connect the telephone ringing generator to the line, Figure 12, SW3 and SW4. Applied
5-volt logic signals control the condition of the switches to perform the functions of line disconnect, connection to the SLIC and application of
ringing. If excessive long-term overdissipation occurs, a thermal sensor activates thermal shutdown and opens the switches. The SLIC side of
switches SW1 and SW2 is limited in voltage by internal protectors Th3 and Th4. The line-side of the LCAS is voltage limited by the two TISP
parts.

Additional functions are provided by the `7582 (line test access) and the `7583 (test-in and test-out access). Up to three conventional electro-
mechanical relays may be replaced by the LCAS. The resulting size reduction can double the line density of a line card.
This document covers the types of overvoltage protection required by the '7581 LCAS and how the TISP
part voltages are selected to
provide these requirements. The LCAS '7582 and '7583 are also covered as the additional switches used in these parts are similar to the
'7581.
Specifications are subject to change without notice.

LCAS Switch Ratings
Equivalent Circuit
Figure 13 shows the LCAS switch voltage ratings as breakdown diodes, which must not be allowed to conduct. Each switch has three diodes;
one between poles and the other two from each pole to ground. At 25
C, switches SW1 through to SW3 have breakdown diode voltages of
320 V. Switch SW4 has breakdown diode voltage values of 465 V for the one between poles and 320 V for the two diodes connected to
ground. Note that only protection to ground is required, as in the limit, the inter-switch voltage limitation of
640 V is the same as the switch to
ground limitation of +320 V and -320 V in both polarities.
When a switch is in the off state, the maximum withstand voltage may be set by the switch itself or by the control line to the switch. At 25
C,
the switch terminal to ground voltage rating for all the switches is
320 V. Switches SW1 to SW3 are bidirectional MOS types and can
withstand
320 V between terminals. Switch SW4 is a bidirectional thyristor which is rated at 465 V between terminals.
Overcurrents as well as overvoltages occur on telephone lines. In the on state, the thyristor switch, SW4, is capable of withstanding high levels
of current overload. For currents above about 200 mA, the MOS switches, SW1 to SW3, will go into a current limited condition. This will cause
the voltage to rise across the switch and large amounts of power to be developed. In the longer term, this power loss increases the overall chip
temperature. When the temperature exceeds about 125
C, thermal shutdown occurs and the switches are set to the off state. Without power
loss, the LCAS will cool. Eventually, the thermal trip will reset, setting the switches back in the high power loss condition again. The cycle of
temperature increase, thermal shutdown, temperature decrease and switch re-activation will continue until the overcurrent ceases.

Protector Voltages
Protector working and protection voltage design calculations for the LCAS are described in the IEEE Std. C62.37.1-2000, IEEE Guide for the
Application of Thyristor Surge Protection Devices, pp 40-43. These calculations comprehend:
the temprature variation of LCAS voltage ratings,
increase in protection voltage with ambient temperature rise, long term a.c. heating and under impulse conditions,
decrease in working voltage with ambient temperature fall,
ground-backed and battery-backed ringing configurations (see Figure 13).
These calculation techniques were used to set the TISP
part voltages. Using these TISP
parts allows normal system voltage levels of
100 V
on TIP and
180 V on RING without clipping at 25 C. At 0 C ambient, these voltage levels become 97 V on TIP and 174 V on RING. Under
open circuit line conditions, this means that the peak ringing voltage cannot exceed
174 V for equipment operation down to 0 C ambient.
Assuming a battery voltage of 48 V
2.5 V and battery-backed ringing, the maximum peak a.c. ring voltage is 174 V - 50.5 V = 123.5 V or 87 V
rms. The working voltage of
97 V on TIP is more than half the 174 V working voltage on RING. As a result, the TIP working voltage does not
represent a limitation for systems where the TIP return resistance is equal or less than the RING source resistance.
For balanced impedance ground-backed ringing, the maximum peak a.c. ring voltage under short line conditions (short between TIP and
RING) is limited by the TIP working voltage of
97 V. In the negative ring polarity, the limit of the voltage is made up from half the battery
voltage plus half of the peak a.c. ring voltage. The maximum peak a.c. ring voltage is 2 x (97 - 50.5/2) = 143.5 V or 101 V rms.
Line test voltage levels must be considered, whether they be applied by using LCAS switches or separate electro-mechanical relays. For these
TISP
parts, the applied test voltage should not exceed the lowest working voltage, which is
97 V.
