LTV-702VS-TA

Transistor, Photovoltaic Output Optoisolators Overview

The LTV-702VS-TA is a single-channel optoisolator manufactured by Lite-On Inc., featuring a transistor output with an integrated base. It provides high isolation voltage of 5000Vrms and supports a maximum collector-emitter voltage of 70V. The device operates within a temperature range of -55°C to 100°C, ensuring reliability in demanding environments. Key electrical parameters include a minimum current transfer ratio of 40% at 10mA input current and a maximum forward current of 60mA. The rise and fall times are typically 2µs each, facilitating moderate-speed signal transmission. Packaged in a compact 6-SMD gull wing configuration, it is designed for surface-mount applications requiring galvanic isolation between circuits.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix TA indicates the tape-and-reel packaging format when ordering. Confirm that the 6-SMD gull wing package matches the PCB footprint requirements. Ensure the 5000Vrms isolation rating meets the safety standards of the target application. Check for RoHS compliance status if environmental regulations apply. Validate the operating temperature range against the system's thermal environment.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a transistor output optocoupler with an exposed base is required for improved switching speed or gain control. The 6-SMD package suits automated surface-mount assembly processes. Consider the 40% minimum CTR at 10mA input for driving subsequent stages. The 70V output voltage capability allows flexibility in load connections. Evaluate the 2µs propagation delay against the system's timing constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the LTV-702 series of optoisolators from Lite-On Inc., which are designed for general-purpose isolation applications. The series includes variants with different packages such as DIP and SMD. The LTV-702VS-TA specifically denotes the surface-mount version with tape-and-reel packaging. It shares core electrical characteristics with other members of the family but differs in physical form factor and handling specifications.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes may include other 5000Vrms transistor output optocouplers in 6-SMD packages. Verify pinout compatibility and electrical parameters like CTR and Vceo before substitution. Consider equivalent parts from manufacturers offering similar isolation ratings and package dimensions.
