Frequently Asked Questions
What is the minimum specified isolation voltage?
The minimum isolation voltage (BV) provided is 5000 Vrms.
Can this component be used in safety-critical equipment?
No, it is not warranted for use in applications requiring extraordinarily high quality or reliability, such as medical instruments or airplane equipment.
What is the acceptable operating temperature range?
The stated operating temperature range (opr) is from 40°C to 100°C.
How should these products be disposed of safely?
Follow appropriate regulations; do not dispose of them with other industrial waste or domestic garbage, especially due to the toxic nature of Gallium arsenide (GaAs).
