LTV-826S-TA

Transistor, Photovoltaic Output Optoisolators Overview

The LTV-826S-TA is a dual-channel surface-mount optocoupler from Lite-On Inc. It features a GaAs infrared LED coupled to two NPN silicon phototransistors in an 8-SMD (gull-wing) package. The device provides high isolation voltage of 5000Vrms and supports DC input signals. Key electrical parameters include a typical forward voltage of 1.2V, maximum input current of 50mA, and output voltage rating of 80V. The current transfer ratio ranges from 50% to 600% at IF=5mA. Typical switching times are 4μs rise and 3μs fall. Operating temperature range is -30°C to 100°C.

• Compact gull-wing surface mount packaging suitable for automated assembly processes

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission across isolated ground planes
• Power supply feedback loops for voltage regulation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'TA' corresponds to the gull-wing lead form factor required for your PCB footprint. Confirm that the 8-SMD package dimensions match your design constraints. Ensure the 5000Vrms isolation rating meets safety standards for your application's voltage class. Check if UL or CSA certification is mandatory for your region's compliance requirements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is necessary within a compact surface-mount envelope. Consider the 5000Vrms isolation barrier for high-voltage separation needs. Evaluate the 50-600% CTR range against your drive current capabilities. Verify that the 80V output voltage rating exceeds your circuit's maximum collector-emitter voltage. Assess the -30°C to 100°C operating range against environmental conditions.

Transistor, Photovoltaic Output Optoisolators Part Context

The LTV-826S-TA belongs to Lite-On's LTV-8x6 series of photocouplers. This family includes variants like LTV-816, LTV-826M, and LTV-846, differing in channel count, package type, or electrical characteristics. The 'S' suffix typically denotes surface mount construction, while 'TA' specifies the lead configuration. These devices are designed for general-purpose isolation applications where space efficiency and reliability are prioritized.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes may include other dual-channel SMD optocouplers with similar 5000Vrms isolation and 8-pin gull-wing packages. Verify pinout compatibility and electrical parameters such as CTR and Vceo before substitution. Cross-reference with datasheets from manufacturers like Vishay, Broadcom, or Everlight for equivalent performance metrics.
