* 1 When maximum carrying current is more than 10A, PCB layout needs to be considered.
* 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 contions
and expected reliability levels.
