LTV-826

Transistor, Photovoltaic Output Optoisolators Overview

The LTV-826 is a dual-channel transistor output optocoupler manufactured by Lite-On Inc. It features two independent phototransistor outputs driven by a single infrared LED, providing electrical isolation between input and output circuits. The device operates within a temperature range of -30°C to 100°C and supports a maximum collector-emitter breakdown voltage of 80V. Key electrical parameters include a minimum current transfer ratio of 50% at an input current of 5mA, with a maximum input forward current of 50mA. The unit offers high insulation capability with a rated isolation voltage of 5000Vrms.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Dual-channel configuration for simultaneous signal isolation
• High insulation voltage rating for safety-critical applications
• Wide operating temperature range suitable for industrial environments

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring isolated signal transmission
• Power supply feedback loops for voltage regulation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific package variant when ordering, as the base part number may correspond to different physical packages such as DIP or SMD depending on the suffix. Confirm that the required current transfer ratio meets the design specifications, as values can vary based on manufacturing tolerances and input conditions. Ensure compatibility with the intended PCB footprint and soldering profile during procurement planning.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required within a compact form factor. Consider the 80V collector-emitter voltage limit to ensure it exceeds the peak load voltage in the application circuit. Evaluate the thermal management requirements given the 100°C maximum junction temperature. Compare against single-channel alternatives if only one isolated path is needed to optimize board space and cost.

Transistor, Photovoltaic Output Optoisolators Part Context

The LTV-826 belongs to the LTV-8x6 series of photocouplers from Lite-On Inc., which includes single, dual, and quad-channel variants. This series is designed for general-purpose isolation applications, offering reliability and performance standards typical of industrial-grade optoelectronic components. The dual-channel architecture allows for efficient use of board space compared to using two separate single-channel devices.
