description
The TISP3xxxH3SL limits overvoltages between the telephone line Ring and Tip conductors and Ground.
Overvoltages are normally caused by a.c. power system or lightning flash disturbances which are induced or
conducted on to the telephone line.
The protector consists of two symmetrical voltage-triggered bidirectional thyristors. 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 TISP3xxxH3SL range consists of eleven voltage variants to meet various maximum system voltage
levels (58 V to 275 V). They are guaranteed to voltage limit and withstand the listed international lightning
surges in both polarities. These high current protection devices are in a 3-pin single-in-line (SL) plastic
package and are supplied in tube pack. For alternative impulse rating, voltage and holding current values in
SL packaged protectors, consult the factory. For lower rated impulse currents in the SL package, the 35 A
10/1000 TISP3xxxF3SL series is available.
These monolithic protection devices are fabricated in ion-implanted planar structures to ensure precise and
matched breakover control and are virtually transparent to the system in normal operation.

† FCC Part 68 terminology for the waveforms produced by the ITU-T recommendation K21 10/700 impulse generator
If the impulse generator current exceeds the protectors current rating then a series resistance can be used to
reduce the current to the protectors rated value and so prevent possible failure. The required value of series
resistance for a given waveform is given by the following calculations. First, the minimum total circuit
impedance is found by dividing the impulse generators peak voltage by the protectors rated current. The
impulse generators fictive impedance (generators peak voltage divided by peak short circuit current) is then
subtracted from the minimum total circuit impedance to give the required value of series resistance. In some
cases the equipment will require verification over a temperature range. By using the rated waveform values
from Figure 10, the appropriate series resistor value can be calculated for ambient temperatures in the range
of -40 °C to 85 °C.
a.c. power testing
The protector can withstand the G return currents applied for times not exceeding those shown in Figure 8.
Currents that exceed these times must be terminated or reduced to avoid protector failure. Fuses, PTC
(Positive Temperature Coefficient) resistors and fusible resistors are overcurrent protection devices which can
be used to reduce the current flow. Protective fuses may range from a few hundred milliamperes to one
ampere. In some cases it may be necessary to add some extra series resistance to prevent the fuse opening
during impulse testing. The current versus time characteristic of the overcurrent protector must be below the
line shown in Figure 8. In some cases there may be a further time limit imposed by the test standard (e.g. UL
1459 wiring simulator failure).
capacitance
The protector characteristic off-state capacitance values are given for d.c. bias voltage, VD, values of 0, -1 V,
-2 V and -50 V. Where possible values are also given for -100 V. Values for other voltages may be calculated
by multiplying the VD = 0 capacitance value by the factor given in Figure 6. Up to 10 MHz the capacitance is
essentially independent of frequency. Above 10 MHz the effective capacitance is strongly dependent on
connection inductance. In many applications, the typical conductor bias voltages will be about -2 V and -50 V.
Figure 7 shows the differential (line unbalance) capacitance caused by biasing one protector at -2 V and the
other at -50 V.

normal system voltage levels
The protector should not clip or limit the voltages that occur in normal system operation. For unusual
conditions, such as ringing without the line connected, some degree of clipping is permissible. Under this
condition, about 10 V of clipping is normally possible without activating the ring trip circuit.
Figure 9 allows the calculation of the protector VDRM value at temperatures below 25 °C. The calculated value
should not be less than the maximum normal system voltages. The TISP3290H3, with a VDRM of 220 V, can
be used for the protection of ring generators producing 105 V rms of ring on a battery voltage of -58 V. The
peak ring voltage will be 58 + 1.414*105 = 206.5 V. However, this is the open circuit voltage and the
connection of the line and its equipment will reduce the peak voltage.
For the extreme case of an unconnected line, the temperature at which clipping begins can be calculated
using the data from Figure 9. To possibly clip, the VDRM value has to be 206.5 V. This is a reduction of the
220 V 25 °C VDRM value by a factor of 206.5/220 = 0.94. Figure 9 shows that a 0.94 reduction will occur at an
ambient temperature of -32 °C. In this example, the TISP3290H3 will allow normal equipment operation, even
on an open-circuit line, provided that the minimum expected ambient temperature does not fall below -32 °C.
JESD51 thermal measurement method
To standardise thermal measurements, the EIA (Electronic Industries Alliance) has created the JESD51
standard. Part 2 of the standard (JESD51-2, 1995) describes the test environment. This is a 0.0283 m3 (1 ft3)
cube which contains the test PCB (Printed Circuit Board) horizontally mounted at the centre. Part 3 of the
standard (JESD51-3, 1996) defines two test PCBs for surface mount components; one for packages smaller
than 27 mm on a side and the other for packages up to 48 mm. The thermal measurements used the smaller
76.2 mm x 114.3 mm (3.0 “ x 4.5 “) PCB. The JESD51-3 PCBs are designed to have low effective thermal
conductivity (high thermal resistance) and represent a worse case condition. The PCBs used in the majority
of applications will achieve lower values of thermal resistance and so can dissipate higher power levels than
indicated by the JESD51 values.

MECHANICAL DATA
SL003
3-pin plastic single-in-line package
This single-in-line package consists of a circuit mounted on a lead frame and encapsulated within a plastic compound. The compound will withstand soldering temperature with no deformation, and circuit performance characteristics will remain stable when operated in high humidity conditions. Leads require no additional cleaning or
processing when used in soldered assembly.
