* 1 Need to consider the heat from PCB when max. current is more than 10A
* 2 Minimum switching loads mentioned above are reference values. Please perform the confirmation test with actual
load before production since reference values may vary according to switching frequencies, environmental conditions
and expected reliability levels.
