TISP4360H3BJ

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 TISP4360H3BJ 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.
