Overview
The DPC817W-X-TU-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an MDIP-4 package with through-hole mounting and provides 5000 Vrms insulation voltage. Key electrical parameters include a collector-emitter saturation voltage of 200 mV, a forward voltage of 1.25 V at 5 mA forward current, and a maximum collector current of 30 mA. The device operates within a temperature range of -55°C to +110°C and has a power dissipation rating of 200 mW.
Feature Summary
- Provides high-voltage isolation between input and output circuits
- Utilizes a phototransistor output configuration for signal transmission
- Designed for reliable operation 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 'X' against the official Diodes Incorporated datasheet to confirm the exact Current Transfer Ratio (CTR) binning, as variations exist within the DPC817W series. Ensure the MDIP-4 package type matches the target PCB footprint requirements. Confirm RoHS compliance status directly from the manufacturer's documentation prior to procurement.
Selection Notes
Select this component when a single-channel phototransistor output is required for moderate-speed signal isolation. The MDIP-4 package suits through-hole assembly processes. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the 130% to 600% CTR range to ensure adequate drive capability for the downstream load circuitry.
Part Context
This part belongs to the DPC817W series of optocouplers from Diodes Incorporated. The series includes variants with different CTR bins and certification levels, such as VDE approvals. The DPC817W-X-TU-V specifically denotes a tube-packaged unit within this family, sharing core electrical characteristics with other members like the DPC817W-B-TU-V while differing in performance grading.
Replacement Considerations
Direct substitutes may include DPC817W-B-TU-V or DPC817D-B-TU-V, provided their CTR specifications align with the design requirements. Verify pinout compatibility and isolation voltage ratings before substitution.
