With pin connected to the signal or data line and pin 2 connected to ground both diodes are in series (pin remains unconnected). The big and robust avalanche diode, driven in reverse direction, provides the working range V RWM of 5 V, 2 V, 5 V or 24 V. Due to its size the capacitance of the avalanche diode is in the range of typ. 260 pf (GL05T) and 65 pf (GL24T). The small switching diode in series has a low capacitance of just 2.5 pf (typ.). As both diodes are in series (with pin not connected) the total capacitance of both diodes measured between pin and 2 is as low as the capacitance of the switching diode. Before the GLxxT can provide this low capacitance the big capacitance of the avalanche diode has to be charged up with the first signal or data pulses. This is usually no problem for digital signals like USB or other data ports. With the GLxxT a signal or data line can be protected against positive transients only. For negative transients another GLxxT can be used to provide a back path for the negative transients as well. Rev. 2., 07-Mar-6 2 Document Number: ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT
