DPC817W-D-TU

Overview

The DPC817W-D-TU is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features a phototransistor output and operates in a DIP-4 through-hole package. Key electrical parameters include a minimum current transfer ratio of 80% at an input forward current of 5 mA, with a maximum CTR of 260%. The device supports a maximum collector-emitter voltage of 35 V and a collector current of 30 mA. It provides high isolation capability with a rated insulation voltage of 5000 Vrms. The component has a typical rise time of 18 microseconds and a power dissipation rating of 200 mW.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Features a single channel with phototransistor output configuration
• Includes safety approval for regulatory compliance

Applications

• Industrial control systems requiring signal isolation
• Consumer electronics with high-voltage separation needs
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'D' against official Diodes Incorporated documentation to confirm the exact Current Transfer Ratio (CTR) binning, as variations exist within the DPC817 series. Ensure the DIP-4 tube packaging aligns with assembly requirements. Cross-reference the manufacturer part number directly with the datasheet to avoid confusion with similar models like the DPC817W-A or B variants.

Selection Notes

Select this component when a single-channel isolation solution with a guaranteed minimum CTR of 80% is required. The 5000 Vrms isolation rating makes it suitable for applications demanding robust barrier protection. Consider the 35 V collector-emitter voltage limit for low-voltage logic interfacing. The through-hole DIP-4 package is appropriate for standard PCB mounting techniques.

Part Context

This device belongs to the DPC817 series of transistor output optocouplers from Diodes Incorporated. The series is designed for general-purpose isolation tasks. The 'W' indicates a wide body package variant, while 'TU' denotes the tube packaging format. This specific model represents one of several CTR bins available within the family.

Replacement Considerations

Compatible substitutes include other DPC817 series variants such as DPC817W-A-TU or DPC817W-B-TU, provided the specific CTR requirements are met. Verify pinout compatibility and isolation voltage ratings before substitution.
