Why is safety standards needed to RE photocoupler and optical MOS FET?

Latest Updated:11/01/2007

Question:

Renesas Electronics' photocoupler and optical MOS FET products meet many overseas safety standards, but why is this necessary?

Answer:

There are regulations applying to the isolation of the primary circuit and secondary circuit in sets incorporating photocouplers (power supplies, FA devices, etc.). The photocoupler accomplishes this isolation function. Therefore, if the photocouplers meet these regulations, the sets themselves may be exempted from the relevant qualification tests. This is why Renesas Electronics has developed photocouplers to meet these overseas safety regulations.
