LTV-845S-TA1

Transistor, Photovoltaic Output Optoisolators Overview

The LTV-845S-TA1 is a quad-channel surface-mount optocoupler featuring Darlington transistor outputs. It provides high current transfer ratios ranging from 600% to 7500% at a 1mA input, ensuring robust signal transmission. The device offers 5000 Vrms isolation voltage for effective circuit separation. It operates with a maximum forward current of 50 mA and supports DC input signals. Typical rise and fall times are 60µs and 53µs respectively. Packaged in a 16-pin gull-wing DIP format, it suits applications requiring multiple isolated channels.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix TA1 confirms the tape-and-reel packaging variant when sourcing. Ensure the procurement specification matches the required Darlington output type and 16-pin SMD package dimensions. Cross-reference the manufacturer part number against official Lite-On documentation to confirm authenticity and avoid counterfeit components during acquisition.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are required within a single footprint. The high CTR makes it suitable for driving loads directly without additional amplification. Consider the slower switching speed compared to logic outputs when designing for high-frequency applications. Ensure the PCB layout accommodates the 16-pin gull-wing package spacing and isolation creepage requirements.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the Lite-On LTV series of optocouplers, designed for general-purpose isolation. The LTV-845S variant represents the standard through-hole or surface-mount equivalent, while the TA1 suffix specifically denotes the reel packaging format. It complements other channel counts in the family by providing four independent isolation paths.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements include the LTV-845S for non-reel packaging or other quad-channel Darlington optocouplers with matching pinouts and electrical ratings. Verify that substitute parts maintain the 5000 Vrms isolation and similar CTR ranges to ensure circuit compatibility.
