V max ?= Maximum operating voltage device can withstand without damage at rated current (Imax).
I max ? = Maximum fault current device can withstand without damage at rated voltage (V max).
I hold ? = Hold Current. Maximum current device will not trip in 25°C still air.
I trip ? ?= Trip Current. Minimum current at which the device will always trip in 25°C still air.
Pd ? ? ?= Power dissipation when device is in the tripped state in 25°C still air environment at rated voltage.
Ri min/max ?= Minimum/Maximum device resistance prior to tripping at 25°C.
R1max ?= Maximum device resistance is measured one hour post reflow.
CAUTION : Operation beyond the specified ratings may result in damage and possible arcing and flame.
