description
The TISP4360H3BJ is designed to limit overvoltages on equipment used for telephone lines carrying POTS
(Plain Old Telephone System) and ADSL (Asymmetrical Digital Subscriber Line) signals. TISP4360H3BJ a.c.
overload limits are specified for designers to select the correct overcurrent protectors to meet safety
requirements, e.g. UL 1950.
The protector consists of a symmetrical voltage-triggered bidirectional thyristor. Overvoltages are initially
clipped by breakdown clamping. If sufficient current is available from the overvoltage, the breakdown voltage
will rise to the breakover level, which causes the device to switch into a low-voltage on-state condition. This
switching action removes the high voltage stress from the following circuitry and causes the current resulting
from the overvoltage to be safely diverted through the protector. The high holding (switch off) current prevents
d.c. latchup as the diverted current subsides.
The TISP4360H3BJ is guaranteed to voltage limit and withstand the listed international lightning surges in
both polarities. This high (H) current protection device is in a plastic SMBJ package (JEDEC DO-214AA with
J-bend leads) and supplied in embossed carrier reel pack. For alternative voltage and holding current values,
consult the factory.

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 SMBJ 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.
