Frequently Asked Questions
What is the minimum required isolation voltage for this optocoupler?
The minimum isolation voltage (AC, 1 min., R.H. ≤ 60%) is 2500 V rms.
Can I use this device in life-support or medical equipment?
No; the product warns against 'Unintended Usage' in areas like medical instruments or airplane/spaceship equipment due to reliability requirements.
When designing my circuit, how should I connect the leads?
The device must be considered a two-terminal unit: LED side pins are shorted together, and detector side pins are shorted together.
