TISP7072F3

The TISP7xxxF3 series are 3-point overvoltage protectors designed for protecting against metallic (differential mode) and simultaneous longitudinal (common mode) surges. Each terminal pair has the same voltage limiting values and surge current capability. This terminal pair surge capability ensures that the protector can meet the simultaneous longitudinal surge requirement which is typically twice the metallic surge requirement.

Each terminal pair TISP7xxxF3 series has a symmetrical voltagetriggered thyristor characteristic. 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.These protectors are guaranteed to voltage limit and withstand the listed lightning surges in both polarities.

These low voltage devices TISP7xxxF3 series are guaranteed to suppress and withstand the listed international lightning surges on any terminal pair. Nine similar devices with working voltages from 100 V to 275 V are detailed in the TISP7125F3 thru TISP7380F3 data sheet.
