Product details
Overview
DPC817W-A-TU-V from Diodes Incorporated is a high-isolation, single-channel phototransistor optocoupler in MDIP-4 package, featuring 80–160% CTR at IF = 5 mA / VCE = 5 V, 5000 VRMS input-output isolation voltage, 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.
For engineers reviewing the DPC817W-A-TU-V datasheet, DPC817W-A-TU-V pinout, DPC817W-A-TU-V application, or DPC817W-A-TU-V equivalent, this page delivers verified electrical parameters, safety certifications (UL1577, VDE EN IEC 60747-5-5), CTR rank-specific performance, and real-world isolation design guidance for industrial and power electronics systems.
Technical Context
This optocoupler integrates an AlGaAs infrared LED emitter coupled to a silicon NPN phototransistor output stage, enabling DC or low-frequency AC signal transmission across an electrically isolated barrier. Its 35 V VCEO rating supports operation in 24 V and 48 V control-side systems with margin.
The device achieves 80–160% current transfer ratio under standard test conditions (IF = 5 mA, VCE = 5 V), with typical response times of ≤18 µs (rise/fall) into 100 Ω load, supporting switching frequencies up to 80 kHz. It meets VDE EN IEC 60747-5-5 and UL1577 safety standards for reinforced insulation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar phototransistor optocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PC817XNIP0X | Same MDIP-4 package, but CTR min = 80% at IF = 5 mA, VCE = 5 V; lacks VDE certification. | No VDE EN IEC 60747-5-5 approval; unsuitable for designs requiring certified reinforced insulation. | Select only for cost-sensitive non-safety-critical applications where UL1577 suffices. |
| TLP183(GB-TP,F) | Higher CTR (100–300%), same 5000 VRMS isolation, but TO-243AA (SOT-89) package - surface-mount only. | Requires PCB redesign for SMT layout; not drop-in compatible with through-hole MDIP-4 footprint. | Choose when board space is constrained and higher gain justifies re-layout effort. |
Compared with PC817XNIP0X and TLP183(GB-TP,F), DPC817W-A-TU-V uniquely combines VDE certification, MDIP-4 through-hole compatibility, and guaranteed CTR rank A - making it optimal for industrial power supplies and safety-rated I/O modules where regulatory compliance and mechanical robustness are mandatory.

FAQ
What safety certifications does DPC817W-A-TU-V hold?
DPC817W-A-TU-V is certified to UL1577 (5000 VRMS, 1 minute) and VDE EN IEC 60747-5-5 (reinforced insulation). The "-V" suffix explicitly denotes VDE qualification. It also complies with RoHS 3 and Diodes' "Green" material standards (halogen- and antimony-free).
How does CTR Rank A affect circuit design?
CTR Rank A guarantees 80–160% current transfer ratio at IF = 5 mA and VCE = 5 V. This allows designers to size the input current-limiting resistor with confidence, ensuring phototransistor saturation across temperature and aging - critical for stable feedback in SMPS and reliable logic-level translation in I/O modules.
Can DPC817W-A-TU-V replace DPC817D-A-TU-V in existing designs?
Yes - both share identical electrical specifications, safety certifications, and CTR ranking. The only difference is package: DPC817W-A-TU-V uses MDIP-4 (narrower body, longer eA dimension), while DPC817D-A-TU-V uses standard DIP-4. PCB footprint must be verified for mechanical fit and creepage clearance.
What is the maximum recommended input forward current?
The absolute maximum rated forward current is 60 mA, but continuous operation above 20 mA accelerates LED degradation. Diodes specifies 5 mA as the standard test condition for CTR; typical design practice uses 5–10 mA for optimal lifetime and linearity. Peak pulses up to 1 A are allowed for <1 µs at 300 pps.
