DPC817D-D-TU-V

Transistor, Photovoltaic Output Optoisolators Overview

The DPC817D-D-TU-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features a phototransistor output and is housed in a DIP-4 through-hole package. Key electrical specifications include an isolation voltage of 5000 Vrms, a maximum collector-emitter voltage of 35 V, and a maximum collector current of 30 mA. The device operates with a forward current of 5 mA and has a typical forward voltage of 1.25 V. The current transfer ratio ranges from 130% to 260%, with rise and fall times of 18 µs. It supports a power dissipation of 200 mW and functions within a temperature range of -55°C to +110°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high-voltage isolation between input and output circuits via optical coupling.
• Utilizes a phototransistor output for digital signal transmission.
• Designed for through-hole mounting in standard DIP-4 packages.

Transistor, Photovoltaic Output Optoisolators Applications

• General-purpose signal isolation in industrial control systems
• Microcontroller interface circuits requiring galvanic isolation
• Power supply feedback loops

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific CTR bin (D) against design requirements, as it differs from other variants like A or B. Confirm the suffix TU-V indicates tube packaging. Ensure compatibility with existing DIP-4 footprints. Check RoHS compliance status on the official datasheet before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a standard 80-600% CTR range is acceptable but a tighter specification is preferred over the generic DPC817D. Compare the 35V collector-emitter voltage limit against system requirements. Consider the 18µs switching speed for frequency limitations. Evaluate thermal management needs given the 200mW power dissipation rating.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the DPC817 series of transistor output optocouplers from Diodes Incorporated. It shares the same physical footprint and basic electrical characteristics as other variants in the family, differing primarily in the Current Transfer Ratio (CTR) binning. The 'D' suffix denotes a specific CTR range, while 'TU-V' specifies the tube packaging format.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other DPC817D variants such as DPC817D-A-TU-V or DPC817D-B-TU-V, provided their respective CTR bins meet the application's gain requirements. Generic replacements must match the DIP-4 package, 5000Vrms isolation, and 35V Vceo specifications.
