IH=Hold current-maximum current at which the device will not trip at 23ºC still air.
IT=Trip current-minimum current at which the device will always trip at 23ºC still air.
V MAX=Maximum voltage device can withstand without damage at its rated current.
I MAX= Maximum fault current device can withstand without damage at rated voltage (V
MAX).
Pd=Typical power dissipated from device when in the tripped state in 23ºC still air environment.
RMIN=Minimum device resistance at 23ºC.
R1MAX=Maximum device resistance at 23ºC 1 hour after tripping .
Termination pad characteristics
Termination pad materials : solder-plated copper
