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.
Care shall be taken on the heat generated on PC board when maximum carrying current exceeds 10A. Please perform the confirmation test
with actual conditions.
