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...
