Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'A' against the manufacturer's official datasheet to confirm if it denotes a standard RoHS-compliant variant or a specific packaging option. Ensure the ordering code matches the required tape-and-reel quantity. Cross-reference the isolation voltage rating and safety certifications with the final application requirements before purchase.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when space constraints require a low-profile surface-mount solution with robust isolation characteristics. The 35V collector-emitter voltage and 50mA output current make it suitable for driving moderate loads. Consider the 4μs/3μs switching speeds for applications requiring moderate signal transmission rates without excessive delay.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the LTV series of miniature photocouplers from Lite-On. The series is designed for applications demanding small form factors and high reliability.
