C650 and C850 Series TBU ? High-Speed Protectors
Reference Application
The C-series devices are general protectors that can be used in a variety of applications. The basic operation of the device will be
demonstrated using the single line application shown in the ?gure below. The test circuit was subjected to a 1000 V, 10/700 μs surge
waveform. The devices used were the TBU-C850-100-WH and a 2031-42T-SM-RPLF GDT (OVP) with a 10 ohm resistor for the load
impedance.

General Application Circuit
The graph below shows the waveforms for the voltage across the overvoltage protector (GDT) and the current through the TBU ?
device. As the input line voltage increases, the current through the TBU ? device increases rapidly until the trip current is reached. Due
to ?nite reaction time for fast transients, the peak level may exceed the low frequency data sheet maximum for a very short period,
typically ~100 ns. After this initial overshoot, the TBU ? device will transition to the protected state, setting the current to the nominal
current limiting level (~150 mA for this example). The TBU ? device will then reduce the current down it to its very low quiescent level
of 1 mA, typically. As the input line voltage increases to about 500 V, the GDT is triggered, reducing the input line voltage to a very low
level which prevents the TBU ? device from being subjected to a voltage level which exceeds its maximum rating (850 V in this
example). The TBU ? High-Speed Orotector and the GDT will remain in these states until the surge ends, which is about 700 μs later
in this example. Only the ?rst 4 μs of the surge are shown in the graph. For surges or AC voltages below the GDT breakover voltage,
the GDT will not activate, and the TBU ? device will stay in the protecting mode, blocking high voltages from the protected equipment.
