Due to the different clamping levels in forward and reverse direction the clamping behavior is Bidirectional and Asymmetric (BiAs). 3-Channel EMI-Filter with ESD-Protection L1IN L2IN L3IN 1 7 2 3 6 5 4 L1OUT L2OUT L3OUT 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. 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 In (pin 1, 2, 3) CD Out (pin 4, 5, 6) CD GND (pin 7) 21060 Each filter is symmetrical so that both ports can be used as input or output. www.vishay.com 2 For technical questions, contact: EMIFilter@vishay.com Document Number: 83313 Rev. 1.0, 21-Apr-10 VEMI355A-HAF 3-Channel EMI-Filter with ESD-Protection Vishay Semiconductors ELECTRICAL CHARACTERISTICS VEMI355A-HAF (Tamb = 25 °C, unless otherwise specified) PARAMETER Protection paths Reverse stand off voltage Reverse current Reverse break down voltage TEST CONDITIONS/REMARKS Number of channels which can be protected at IR = 1 μA each input to pin 2 at VR = 5 V each input to pin 2 Each input to pin 2 at IR = 1 mA at IPP = 1 A applied at the input, measured at the output; acc.
