Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the complete part number suffix against official Lite-On documentation, as variations such as TA1 or TP-A indicate specific packaging or tape-and-reel configurations. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the selected variant matches the required surface-mount package type and isolation voltage ratings for the target application.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high gain is required due to its photodarlington architecture. Consider the 300 µs rise time for timing-sensitive applications, as it is slower than standard transistor outputs. Verify that the 35 V collector-emitter voltage rating meets the load requirements. Ensure the 5000Vrms isolation barrier satisfies safety standards for the intended circuit interface.
