DPC817W-Y-TU-V

Overview

The DPC817W-Y-TU-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an MDIP-4 package with through-hole mounting. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 30 mA, and a forward voltage of 1.25 V at 5 mA forward current. The device offers a high isolation voltage of 5000 Vrms. The current transfer ratio ranges from 150% to 300%. Rise and fall times are specified at 18 µs, with a maximum collector-emitter saturation voltage of 200 mV.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits via optical coupling.
• Utilizes a phototransistor output configuration for signal transmission.
• Designed for robust performance across extended industrial temperature ranges.

Applications

• Industrial control systems requiring galvanic isolation
• Consumer electronics signal interfacing
• Power supply feedback loops

Procurement Notes

Verify the specific suffix Y-TU-V against official Diodes Incorporated documentation to confirm the exact Current Transfer Ratio bin (150%-300%) and VDE certification status. Ensure the MDIP-4 package dimensions match your PCB footprint requirements. Cross-reference the datasheet revision date to ensure compliance with current safety standards before finalizing procurement specifications.

Selection Notes

Select this component when an 80 V collector-emitter voltage rating is required, distinguishing it from lower-voltage variants like the DPC817W-B-TU-V which is rated for 35 V. The 150%-300% CTR range suits applications needing higher gain than standard bins. Confirm that the 18 µs switching speed meets the system's timing constraints for signal isolation tasks.

Part Context

This part belongs to the DPC817 series of single-channel optocouplers. It shares the same physical MDIP-4 package and basic pinout as other series members but differs in electrical grading. The 'Y' suffix specifically denotes the 150%-300% Current Transfer Ratio bin, while the '-V' indicates VDE certification for enhanced safety compliance in regulated markets.

Replacement Considerations

Direct substitutes within the same family include DPC817W-D-TU-V (100%-200% CTR) or DPC817W-X-TU-V (100%-200% CTR). Note that these alternatives have different current transfer ratios and may require circuit adjustment. Verify that any replacement maintains the 80 V collector-emitter voltage rating if used in place of the Y variant.
