Abstract
A hybrid circuit protection device includes a positive temperature coefficient (PTC) component, a voltage-dependent resistor, a gas discharge tube (GDT), and first and second conductive leads that are respectively connected to the PTC component and the GDT. The voltage-dependent resistor and the PTC component are electrically connected in series, the GDT is electrically connected to the voltage-dependent resistor and the PTC component, and the GDT has a breakdown voltage greater than a varistor voltage of the voltage-dependent resistor as determined at 1 mA.
