Vmax: Maximum Continuous Voltage device can withstand without damage at Rated Current.
Imax: Maximum Fault Current device can withstand without damage at Rated Voltage.
Ihold: Holding Current, Maximum Current at which the device will not interrupt in 25℃ still air.
Itrip: Tripping Current, Minimum Current at which the device from low resistance to high resistance in 25℃ still air.
Pd: Typical amount of power dissipated from the device when in 25℃ still air environment.
Maximum Time-to-trip: Maximum time to trip at assigned Current.
Rmin: Minimum resistance of device in initial (un-soldered) state.
R1Max: Maximum resistance of device is measured on hour post reflow.
