Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix configuration against the official Toshiba datasheet to ensure the correct packaging and binning match the design requirements. Confirm that the DIP-4 form factor aligns with the target PCB footprint and thermal management constraints. Cross-reference the current transfer ratio rank to guarantee it meets the minimum system threshold for reliable switching operation under all expected operating temperatures.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and moderate speed are required for single-channel DC isolation. The DIP-4 package suits through-hole mounting applications where long creepage distances are necessary. Consider the wide CTR range for designs requiring robust signal integrity without tight binning constraints. Ensure the 80 V collector-emitter voltage rating exceeds the maximum load voltage in the target circuit application.
