1.5 Unidirectional vs. Bidirectional

A bidirectional ESD diode has both a negative and a positive working voltage range, generally from –3.6 V to 3.6 V or –5.5 V to 5.5 V. This allows for the bidirectional ESD device to function with the interfaces whose data signals toggle between positive and negative voltages. A unidirectional ESD only has a positive working voltage range while having better negative clamping.
