Product details
Overview
DPC817D-A-TU-V from Diodes Incorporated is a high-isolation, single-channel phototransistor coupler with 5000 VRMS input-output isolation, 80–160% CTR at IF = 5 mA / VCE = 5 V, and -55°C to +110°C operating temperature range. It provides galvanic signal transfer in AC/DC power supply feedback loops, PLC I/O isolation, and industrial sensor interface circuits where safety-rated insulation and stable current transfer are required.
For engineers reviewing the DPC817D-A-TU-V datasheet, DPC817D-A-TU-V pinout, DPC817D-A-TU-V application, or DPC817D-A-TU-V equivalent, this page delivers verified specifications, real-world use cases, VDE-certified safety context, and direct comparison with functionally aligned alternatives for industrial control and power management designs.
Technical Context
The DPC817D-A-TU-V integrates an AlGaAs infrared LED paired with a silicon NPN phototransistor in a DIP-4 package. Its internal structure enables DC-coupled signal transmission with no external bias required on the output side, supporting linear and switching operation modes depending on load configuration.
It meets VDE EN IEC 60747-5-5, UL1577, and CQC 4943.1-2022 safety standards, with guaranteed 5000 VRMS isolation and ≥5×10¹⁰ Ω isolation resistance. The device operates across full industrial temperature extremes without CTR derating below 50% minimum at end-of-life conditions.

IC Role / Device Role / Timing Role: Provides galvanically isolated current-mode signal transfer; replaces optocoupler-based compensation networks requiring external bias. Use Value: Maintains loop stability across 35 V CBO rating and 18 µs response - enables <50 kHz feedback bandwidth without phase lag penalties. |
Use Scenario: Interfaces 24 V DC field sensors (e.g., proximity switches) to 3.3 V/5 V microcontroller inputs in programmable logic controllers. IC Role / Device Role / Timing Role: Acts as input stage isolator; converts high-voltage digital signals into logic-compatible levels while breaking ground loops. Use Value: 5000 VRMS isolation withstands surge transients per IEC 61000-4-5 Level 3; CTR range ensures robust detection across voltage tolerances and cable lengths. |
| Industrial Motor Drive I/O | Medical Equipment Signal Barrier |
Use Scenario: Isolates enable/disable and fault signals between MCU-based gate driver boards and high-power IGBT modules in variable frequency drives. IC Role / Device Role / Timing Role: Delivers fast, noise-immune digital signaling across high dv/dt zones; collector output directly interfaces with Schmitt-trigger inputs. Use Value: 18 µs max rise/fall time supports 20 kHz PWM command updates; -55°C to +110°C rating matches IGBT heatsink thermal envelope. |
Use Scenario: Segregates patient-connected ECG front-end analog stages from digital processing units in Class II medical devices. IC Role / Device Role / Timing Role: Forms part of reinforced insulation barrier per IEC 60601-1; transfers alarm or status signals without compromising patient safety. Use Value: VDE EN IEC 60747-5-5 certification satisfies clause 8.8.3 for creepage/clearance validation - eliminates need for custom barrier layout verification. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar phototransistor coupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP183(TPL,E | CTR 50–600%, VCEO = 80 V, same DIP-4 footprint | Higher VCEO supports 48 V bus monitoring; wider CTR spread increases calibration burden in precision feedback | Select when higher output voltage headroom is needed; avoid if tight CTR tolerance is critical |
| PC817XNIP0X | CTR 80–160%, VCEO = 35 V, same DIP-4, but only UL1577 certified (no VDE) | Lacks VDE EN IEC 60747-5-5 - insufficient for EU medical or industrial safety certifications requiring VDE | Acceptable for non-safety-regulated consumer power supplies; not suitable for CE-marked industrial equipment |
Compared with TLP183(TPL,E and PC817XNIP0X, the DPC817D-A-TU-V uniquely combines VDE certification, tightly binned CTR (80–160%), and industrial temperature range in one DIP-4 package - making it optimal for safety-compliant, high-reliability feedback and I/O isolation where certification traceability and parameter consistency are mandatory.

FAQ
What safety certifications does DPC817D-A-TU-V hold?
DPC817D-A-TU-V is certified to UL1577 (5000 VRMS), VDE EN IEC 60747-5-5, and CQC 4943.1-2022. These cover dielectric strength, partial discharge, and construction requirements for reinforced insulation in end equipment. Certification reports are available from Diodes Incorporated upon request with proper NDA coverage.
Can DPC817D-A-TU-V replace PC817 without redesign?
Yes - DPC817D-A-TU-V shares identical DIP-4 pinout, 35 V VCEO, and 80–160% CTR range with PC817XNIP0X variants. However, its VDE EN IEC 60747-5-5 certification adds qualification rigor beyond UL-only parts, enabling drop-in use in CE-marked systems where PC817 may lack approval scope.
What is the maximum recommended forward current for continuous operation?
The absolute maximum rated forward current is 60 mA, but Diodes specifies 5 mA as the test condition for CTR characterization. For continuous operation with >10-year reliability, Diodes recommends limiting IF to ≤20 mA (per Figure 2 VF curve and derating guidelines in DS45855 Rev. 5-2), ensuring junction temperature stays within limits.
Does DPC817D-A-TU-V support linear analog signal transfer?
Yes - its phototransistor output exhibits predictable collector current vs. forward current behavior (Figure 3), enabling analog transfer functions. However, CTR nonlinearity (~±15% over 1–20 mA IF range) and temperature coefficient (-0.1%/°C typical) require calibration or feedback compensation in precision applications.
