Product details
Overview
DPC817W-D-TU-V from Diodes Incorporated is a high-isolation, single-channel phototransistor optocoupler in MDIP-4 package, featuring 5000 VRMS input-output isolation voltage, minimum 50% current transfer ratio (CTR) at IF = 5 mA / VCE = 5 V, and -55°C to +110°C operating temperature range. It enables galvanic signal transfer in industrial power supplies, PLC I/O modules, and AC mains-sensed feedback circuits.
For engineers reviewing the DPC817W-D-TU-V datasheet, DPC817W-D-TU-V pinout, DPC817W-D-TU-V application, or DPC817W-D-TU-V equivalent, key selection criteria include CTR rank (D = 50–600%), VDE-certified isolation compliance, MDIP-4 creepage/clearance performance, and guaranteed operation across extended industrial temperature extremes.
Technical Context
This optocoupler integrates an AlGaAs infrared LED emitter coupled to a silicon NPN phototransistor output stage. Its internal structure provides unidirectional signal transmission with no electrical continuity between input and output sides, supporting safe level-shifting in grounded-referenced control systems interfacing with high-voltage domains.
The device meets VDE EN IEC 60747-5-5, UL1577, and CQC 4943.1-2022 safety standards. Its 5000 VRMS isolation rating and 5×10¹⁰ Ω minimum isolation resistance ensure robust noise immunity and reinforced insulation for functional safety-critical interfaces.

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 only UL1577 certified (no VDE EN IEC 60747-5-5); CTR min 80% (X rank), no -55°C rating. | Lacks VDE certification required for CE-marked industrial equipment; limited to commercial-temp consumer designs. | Select when cost is critical and VDE/IEC 60747-5-5 compliance is not mandated by end-equipment standards. |
| TLP185(GB-TP,F) | Toshiba MDIP-4 part with VDE/UL/CQC approval; CTR min 50%, but specified only to +105°C (not +110°C). | Suitable for most industrial uses but may require derating above 105°C ambient in sealed enclosures. | Choose if existing design uses Toshiba footprint and requires identical thermal margin up to +105°C. |
Compared with PC817XNIP0X and TLP185(GB-TP,F), DPC817W-D-TU-V uniquely combines full VDE EN IEC 60747-5-5 certification, -55°C to +110°C operation, and 50–600% CTR coverage-making it optimal for safety-critical, thermally demanding, and globally certified industrial systems.

FAQ
What safety certifications does DPC817W-D-TU-V hold?
DPC817W-D-TU-V is certified to UL1577 (5000 VRMS), VDE EN IEC 60747-5-5 (reinforced insulation), and CQC 4943.1-2022. These approvals validate its isolation barrier for use in Class I and Class II equipment per IEC 62368-1 and IEC 60950-1, with test reports available upon request.
Does DPC817W-D-TU-V support surface-mount reflow assembly?
Yes. The MDIP-4 package is qualified for lead-free reflow per J-STD-020, with peak solder temperature tolerance up to +260°C. Its matte tin-plated leads meet MIL-STD-202 Method 208 for solderability, and moisture sensitivity level is rated at Level 1 (unlimited floor life).
How does the "D" CTR rank differ from "A", "B", or "C" variants?
The "D" suffix denotes the broadest CTR specification range: 50–600% at IF = 5 mA / VCE = 5 V. In contrast, "A" (80–160%), "B" (130–260%), and "C" (200–400%) denote tighter, binned CTR ranges. "D" provides maximum flexibility for designs tolerant of wide gain variation.
Can DPC817W-D-TU-V replace DPC817W-A-TU-V in an existing design?
Yes, with no layout or schematic changes. Both share identical MDIP-4 package, pinout, isolation rating, and temperature range. The only difference is CTR range: "A" is 80–160%, while "D" covers 50–600%. System-level validation is recommended if minimum CTR was marginal in the original design.
