1. An over-voltage circuit protection device, comprising:
a voltage-dependent resistor component having two opposite resistor surfaces;
a first conductive lead layer and a second conductive lead layer respectively disposed on said two opposite resistor surfaces of said voltage-dependent resistor component; and
a printed circuit board (PCB) component including
a PCB body;
a first conductive portion that is disposed on said PCB body and that is bonded to said first conductive lead layer;
a second conductive Portion that is disposed on said PCB body, that is electrically insulated from said first conductive portion, and that is bonded to said second conductive lead layer;
at least one first conductive via that is formed to extend through said PCB body, and that is defined by a first via-defining wall which is covered by said first conductive portion; and
at least one second conductive via that is formed to extend through said PCB body, and that is defined by a second via-defining wall which is covered by said second conductive portion.
