They have low resistances, normally inside the tens to loads
of milliohms (mΩ), and fast trip instances that are beneath 5 s. PPTC fuses
come in 0402 surface mount applications to limit space in small portable
devices. Instead of an MOV, a TVS diode for overvoltage safety of the DC
circuitry must be taken into consideration. A TVS Zener diode offers circuit
protection from ±30 kV of massive thru-the-air or direct touch ESD strikes.
Also, the TVS diode can adequately soak up as much as 80 A from a lightning
strike.
