Vocabulary
Ihold = Hold current: maximum current device will pass without tripping in 23ºC still air.
Itrip = Trip current: minimum current at which the device will trip in 23 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 23 ºC still air.
Rmin = Minimum resistance of device in initial (un-soldered) state.
R1max = Maximum resistance of device at 23 ºC measured one hour after tripping or reflow soldering of 260 ºC for 20 sec.

·Recommended reflow methods: IR, vapor phase oven, hot air oven,
N2 environment for lead-free
·Recommended maximum paste thickness is 0.25mm (0.010 inch)
·Devices can be cleaned using standard industry methods and
solvents.
Note 1: All temperature refer to topside of the package, measured on
the package body surface.
Note 2: If reflow temperatures exceed the recommended profile,
devices may not meet the performance requirements.
