Electrical Specifications:
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.
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 (Vmax).
JK-SMD2920 Series
Pd=Maximum 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.
R1
max
= Maximum device resistance is measured one hour post reflow.
Recommended pad layout (mm)
Solder reflow conditions
● Recommended 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 (0.010inch).
● Devices can be cleaned using standard industry methods and solvents.
