With pin 2 and 6 connected to ground and pin 1, 3, 4 and 5 connected to a signal- or data-line which has to be protected. As long as the voltage level on the data- or signal-line is between 0 V (ground level) and the specified Maximum Reverse Working Voltage (V RWM) the protection diode between data line and ground offer a high isolation to the ground line. The protection device behaves like an open switch. As soon as any positive transient voltage signal exceeds the break through voltage level of the protection diode, the diode becomes conductive and shorts the tr ansient current to ground. Now the protection device behaves like a closed switch. The Clamping Voltage (VC) is defined by the BReakthrough Voltage (VBR) level plus the voltage drop at the series impedance (resistance and inductance) of the protection device. Any negative transient signal will be clamped accordingly. T he negative transient curr ent is flowing in the forward direction of the protection diode. The low Forward Voltage (VF) clamps the negative transient close to the ground level. Due to the different clamping levels in forward and reverse direction the VESD05A4A-HS4 clamping behaviour is Bi directional and As ymmetrical (BiAs).

Electrical Characteristics

Ratings at 25 °C, ambient temperature unless otherwise specified VESD05A4A-HS4 BiAs mode: each input (pin 1, 3, 4 and 5) to ground (pin 2 and/or 6) If a higher surge current or peak pulse current (I PP) is needed, some protection diodes in the VESD05A4A-HS4 can also be used in parallel in order to "multiply" the performance. If two diodes are switched in parallel you get

  • double surge power = double peak pulse current (2 x IPPM)
  • half of the line inductance = reduced clamping voltage
  • half of the line resistance = reduced clamping voltage
  • double line Capacitance (2 x CD)
  • double Reverse leakage current (2 x IR) Parameter Test conditions/remarks Symbol Min. Typ. Max.

Therefore three pins (example: pin 1, 3, and 5) has to be connected to the signal- or data- line (L1 to L3) and pin 3 to ground. Pin 2 and 6 must not be connected! Positive and negative voltage transients will be clamped in the same way. The clamping current from one data line through the VESD05A4A-HS4 to the ground passes one diode in forward direction and the other one in reverse direction. The Clamping Voltage (VC) is defined by the BReakthrough Voltage (VBR) level of one diode plus the forward voltage of the other diode plus the vo ltage drop at the series impedances (resistances and inductances) of the protection device. Due to the same clamping levels in positive and negative direction the VESD05A4A-HS4 voltage clamping behaviour is also Bi directional and Sy mmetrical (BiSy). Ratings at 25 °C, ambient temperature unless otherwise specified VESD05A4A-HS4 BiSy mode: each input (pin 1, 3, 4 or 5) to any other input pin connected to ground; pin 2 and 6 not connected Parameter Test conditions/remarks Symbol Min.
