APPLICATION NOTE
With the VEMI353A-HAF 3 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 behavior is Bidirectional and Asymmetric (BiAs).

The 3 independent EMI-filter are placed between
pin 1 and pin 6
pin 2 and pin 5, and
pin 3 and pin 4.
They all are connected to a common ground pin 7 on the backside of the package. Each filter is symmetrical so that all ports
(pin 1 to 6) can be used as input or output.
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.
