Due to the different clamping levels in forward and reverse direction the clamping behavior is Bidirectional and Asymmetric (BiAs). L1 L1 IN OUT 1 6 7 L2IN L2OUT 2 5 L3 L3 IN OUT 3 4 19420 19424 19421 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. ) and the diode capacitance (C ). Below the These Z-diodes are characterized by the breakthrough voltage level (V BR D breakthrough voltage level the Z-diodes can be considered as capacitors. Together with these capacitors and the line resistance R between input and output the device works as a low pass filter. Low frequency signals (f < f ) pass the filter S 3dB ) will be shorted to ground through the diode capacitances C . while high frequency signals (f > f 3dB D R S Out In (pin 4, 5, 6) (pin 1, 2, 3) C C D D GND (pin 7) 21060 Each filter is symmetrical so that both ports can be used as input or output.
