Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Solid-state relay driver circuits
• Power supply feedback loops

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the specific ordering suffix matches the required packaging type, as standard tubes differ from tape-and-reel variants like the TA1 designation. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant aligns with the intended mounting style, distinguishing between through-hole DIP and surface-mount SMD configurations to prevent assembly errors.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high current transfer ratios are necessary to drive loads directly without additional amplification stages. The dual-channel design reduces board space compared to using single-channel devices. Consider the 60 µs rise time limitations; this part is unsuitable for high-speed digital communication but ideal for slower switching applications such as power regulation or basic logic isolation where speed is not critical.

Transistor, Photovoltaic Output Optoisolators Part Context

The LTV-825S belongs to the LTV series of optocouplers produced by Lite-On Inc. This series includes single-channel (LTV-815S) and four-channel (LTV-845S) variations. The LTV-825S specifically addresses applications needing two isolated channels. It shares architectural similarities with other photodarlington outputs in the lineup but offers distinct channel density and performance metrics tailored for multi-signal isolation tasks.
