Ihold = Hold current: maximum current device will pass without tripping in 25ºC still air.
Itrip = Trip current: minimum current at which the device will trip in 25 ºC still air.
Vmax = Maximum voltage device can withstand without damage at rated current (I max)
Imax = Maximum fault current device can withstand without damage at rated voltage (Vmax)
Pd typ = Typical power dissipated from device when in the tripped state at 25 ºC still air.
Rmin = Minimum resistance of device in initial (un-soldered) state.
R1max = Maximum resistance of device at 25 ºC measured one hour after tripping or reflow soldering of 260 ºC for 20 sec.
