I hold = Hold current: maximum current device will pass without tripping in 20°C still air.
I trip = Trip current: minimum current at which the device will trip in 20°C still air.
V max = Maximum voltage device can withstand without damage at rated current (I max)
I max = Maximum fault current device can withstand without damage at rated voltage (Vmax)
P d = Power dissipated from device when in the tripped state at 20°C still air.
R min = Minimum resistance of device in initial (un-soldered) state.
R typ = Typical resistance of device in initial (un-soldered) state.
R 1max = Maximum resistance of device at 20°C measured one hour after tripping or reflow
soldering of 260°C for 20 sec.
Caution: Operation beyond the specified rating may result in damage and possible arcing
and flame.

• R ecommended reflow methods: IR, vapor phase oven, hot air
oven, N2 environment for lead-free
• Devices are not designed to be wave soldered to the bottom side
of the board.
• Recommended maximum paste thickness is 0.25mm (0.010 inch)
• Devices can be cleaned using standard industry methods and
solvents.
Note: If reflow temperatures exceed the recommended profile,
devices may not meet the performance requirements.
