Abstract
An over-voltage circuit protection device includes a voltage-dependent resistor component, and a printed circuit board (PCB) component connected to the voltage-dependent resistor component through first and second conductive lead layers. The PCB component includes a PCB body, a first conductive portion, a second conductive portion, at least one first conductive via and at least one second conductive via. The first and second conductive portions are disposed on the PCB body, and are electrically insulated from each other. The first and second conductive vias extend through the PCB body, and are defined by via-defining walls respectively covered by the first and second conductive portions.
