* Devices with hold current up to 1.5 amps are in development
IH=Hold current-maximum current at which the device will not trip at 23°C still air.
IT=Trip current-maximum current at which the device will always trip at 23°C still air.
V MAX=Maximum voltage device can withstand without damage at its rated current (I MAX).
I MAX=Maximum fault current device can withstand without damage at rated voltage (V MAX).
Pd=Typical power dissipated-type amount of power dissipated by the device when in the tripped state in 23°C still air environment.
R MIN=Minimum device resistance at 23°C prior to tripping.
R1MAX=Maximum device resistance at 23°C measured 1 hour post trip.
Termination pad characteristics
Termination pad materials: Tin-plated copper

Solder Reflow
Due to “Lead Free” nature, up to 40 seconds dwelling time for the soldering zone is strongly recommended.
1. Recommended reflow methods; IR, vapor phase oven, hot air oven.
2. The FSMD Series are suitable for use with wave-solder application methods. (Top side only)
3. Recommended maximum paste thickness is 0.25mm.
4. Devices can be cleaned by using standard industry methods and solvents.
5. Storage Environment: <30°C / 60%RH
Caution:
If reflow temperatures exceed the recommended profile, devices may not meet performance requirements.
Rework:
Use standard industry practices.
NOTE: All Specification subject to change without notice.
