APPLICATION NOTE
With the VEMI45LA-HNH 4 different signal or data lines can be filtered and clamped to ground. Due to the different clamping levels in forward and reverse direction the clamping behaviour is Bidirectional and Asymmetric (BiAs).

The 4 independent EMI-filter are placed between pin 1 and pin 8, pin 2 and pin 7, pin 3 and pin 6 and pin 4 and pin 5. They all are connected to a common ground pin 9 on the backside of the package. The circuit diagram of one EMI-filter-channel shows two identical Z-diodes at the input to ground and the output to ground. These Z-diodes are characterized by the breakthrough voltage level (VBR) and the diode capacitance (CD). Below the breakthrough voltage level the Z-diodes can be considered as capacitors. Together with these capacitors and the line resistance RS between input and output the device works as a low pass filter. Low frequency signals (f < f3dB) pass the filter while high frequency signals (f > f3dB) will be shorted to ground through the diode capacitances CD.

Each filter is symmetrical so that both ports can be used as input or output.
