BIAS-MODE (BIDIRECTIONAL ASYMMETRICAL PROTECTION MODE)
With the VESD05A1B-02Z one signal- or data-lines (L1) can be protected against voltage transients. With pin 1 connected to
ground and pin 2 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
between data line and ground offers 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 transient current to ground. Now the protection device behaves like a closed switch. The
Clamping Voltage (V
(resistance and inductance) of the protection device.
Any negative transient signal will be clamped accordingly. The negative transient current is flowing in the forward direction of
the protection diode. The low Forward Voltage (V
Due to the different clamping levels in forward and reverse direction the VESD05A1B-02Z clamping behaviour is Bidirectional
and Asymmetrical (BiAs).
