The protection circuit of the invention connects differentiated grounds in an electronic system either by a single diode, or by two diodes arranged in a back-to-back, parallel fashion. The differentiated grounds may include a chassis ground, a logic ground and an earth ground. The circuit locally connects two of the differentiated grounds, thereby providing a low inductance path for the fast discharging of electrostatic charge build-ups, with the diode(s) therein providing the electrical separation necessary to provide proper local isolation between the interconnected grounds to enable filtering out of electromagnetic interference potentials.
