Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '320E' against the manufacturer's latest datasheet to confirm pinout and packaging details, as suffixes often denote specific tape-and-reel or tube configurations. Confirm RoHS compliance status directly with Broadcom Limited documentation, as availability may vary by region. Check for end-of-life notices or obsolescence warnings prior to finalizing procurement plans.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when designing interfaces requiring galvanic isolation between AC mains or high-voltage DC lines and low-voltage digital logic. The integrated threshold detector simplifies circuit design by eliminating external comparator components. Ensure the load connected to the open collector output does not exceed the 30 mA maximum rating. Verify that the required isolation voltage meets the system safety standards, such as UL or VDE certifications listed in the official specifications.
