Due to the different clamping levels in forward and reverse direction the clamping behaviour is Bidirectional and Asymmetric (BiAs). L1IN L2IN L3IN 1 L1OUT 8 L2OUT 9 2 7 3 6 4 5 L3OUT L4OUT L4IN 20384 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. RS LS In (pin 1, 2, 3, 4) Out (pin 5, 6, 7, 8) CD CD 21526 GND (pin 9) Each filter is symmetrical so that both ports can be used as input or output. www.vishay.com 2 For technical questions, contact: [email protected] Document Number: 81944 Rev. 1.2, 18-May-10 VEMI45LA-HNH 4-Channel EMI-Filter with ESD-Protection Vishay Semiconductors ELECTRICAL CHARACTERISTICS VEMI45LA-HNH PARAMETER TEST CONDITIONS/REMARKS SYMBOL MIN.
