Hello everybody,
I' m looking for an optocoupler that complies with UL 1577 Optical
isolators standard double-protection requirements. I' ve searched the UL

There are manufacturers that make optocouplers with VDE approval. Infineon
(formerly the Siemens' semiconductor division) has a number of optocouplers
that can be ordered with VDE approval as an option. At one time, Siemens
even had some optocouplers with the leads bent to a 0.4 inch (10 mm)
