DATA SHEET BZA420A Quadruple ESD transient voltage suppressor
... BZA420A is determined by the peak transient current and the rate of rise of that current (di/dt). Since parasitic inductances can further add to the clamping voltage (V = L di/dt) the series conductor lengths on the printed-circuit board should be kept to a minimum. This includes the lead length of ...
