Frequently Asked Questions

Which TLP628 model has four isolated channels?

The TLP628−4 provides four isolated channels within the plastic DIP package.

What is the minimum isolation voltage rating for this component?

The absolute minimum stated isolation voltage is 5000Vrms AC for one minute at R.H. ≤ 60%.

Are these components suitable for safety-critical applications like medical instruments?

No, they are not warranted for use in high reliability equipment such as life support or medical instruments ("Unintended Usage").

What precautions should be taken regarding continuous operation under heavy load?

Using the device under continuously heavy loads with significant temperature/current changes may significantly decrease reliability, requiring review of the Semiconductor Reliability Handbook.
