DPC817W-A-TU

Overview

The DPC817W-A-TU is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features a phototransistor output and supports through-hole mounting in a DIP-4 package. Key electrical parameters include an isolation voltage of 5000 Vrms, a collector-emitter saturation voltage of 200 mV maximum, and a forward voltage of 1.25 V. The device operates with a maximum collector current of 30 mA and a maximum collector-emitter voltage of 35 V. Current transfer ratio ranges from 80% to 160%, with rise and fall times specified at 18 µs.

Feature Summary

• Provides high-voltage isolation capability for signal transmission between circuits
• Utilizes a phototransistor output configuration for digital switching applications
• Designed for through-hole integration within standard DIP-4 form factors

Applications

• Industrial control systems requiring galvanic isolation
• Consumer electronics interfaces needing signal separation
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's latest datasheet to confirm binning or performance tier accuracy. Ensure the DIP-4 through-hole package matches your PCB footprint requirements. Cross-reference the 5000 Vrms isolation rating with your system's safety standards compliance needs before finalizing component selection.

Selection Notes

Select this component when a single-channel isolation barrier is required with moderate speed characteristics. The 30 mA collector current limit suits low-power switching tasks. Verify that the 18 µs transition time meets the timing constraints of your application circuit. Ensure the operating temperature range aligns with your environmental specifications.

Part Context

This part belongs to the DPC817 series of transistor output optocouplers from Diodes Incorporated. The series is designed for general-purpose isolation applications. The 'W' designation typically indicates a specific package variant or processing line within the broader 817 family architecture, distinguishing it from other pinout or performance variations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic PC817 variants only if electrical parameters such as CTR and isolation voltage are strictly matched.
