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.
