Additional features include an extended forward bias
safe operating area (FBSOA), fast switching performance and excellent avalanche capabilities.
Once the discharge current falls below the forward bias
levels, the device stops conducting and returns the input lines to their previous condition.
The Forward Bias
Safe Operating Area (FBSOA) characteristic is one such targeted parameter that was optimized, which essentially allowed for a larger operating "window" as dictated by the power limitations of the device.
Assessment of experimental results indicated that when a forward bias
is applied to the body, the direction in which current easily flows, whilst the effectiveness of the control increases, a limit exists after which performance degradation occurs.
In addition, the latest ADSL transceivers, as well as other chips that are sensitive to negative-going transients, are further protected by the LCDA15-1's unidirectional conduction characteristic, which limits the amplitude of negative surges to a forward bias
