Product details
Overview
DPC817W-D-TU from Diodes Incorporated is a high-isolation, single-channel phototransistor optocoupler in MDIP-4 package, featuring 5000 VRMS input-output isolation, CTR ≥50% at IF = 5 mA/VCE = 5 V, BVCEO = 35 V, and operation from −55°C to +110°C. 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-D-TU datasheet, DPC817W-D-TU pinout, DPC817W-D-TU application, or DPC817W-D-TU equivalent, key selection criteria include verified CTR rank (D = 50–600%), UL/VDE safety certification status, MDIP-4 creepage/clearance compliance, and guaranteed performance across extended temperature range without derating.
Technical Context
This optocoupler integrates an AlGaAs infrared LED emitter paired with a silicon NPN phototransistor output stage, enabling DC-coupled digital or analog signal transmission across isolated domains. Its internal structure supports linear-mode operation for analog feedback and saturated switching for digital isolation.
The device meets reinforced insulation requirements per UL 1577 and VDE EN IEC 60747-5-5, with isolation barrier rated for 5000 VRMS for 1 minute and isolation resistance ≥5×1010 Ω. Response time (tR/tF) is ≤18 µs with 100 Ω load, supporting up to 80 kHz bandwidth.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5000 VRMS - enables safe separation between hazardous mains-side and low-voltage control-side in Class I/II AC/DC converters |
| CTR (Min) | 50% at IF = 5 mA, VCE = 5 V - ensures reliable transistor saturation under worst-case aging and temperature conditions |
| VCEO | 35 V - supports direct connection to 24 V industrial logic or 3.3/5 V microcontroller outputs with margin |
| Operating Temp | −55°C to +110°C - qualified for under-hood automotive, industrial motor drives, and outdoor power equipment |
| Response Time | ≤18 µs rise/fall - sufficient for PWM feedback in SMPS operating up to ~30 kHz switching frequency |
| Moisture Sensitivity | Level 1 per J-STD-020 - allows standard SMT reflow without baking preconditioning |
| Safety Certifications | UL 1577, CQC GB 4943.1-2022, VDE EN IEC 60747-5-5 - satisfies regulatory requirements for end-equipment safety approvals |
Pinout & Package
Package: MDIP-4 (Mini Dual In-line Package, 4-pin), 7.62 mm body width, 10.16 mm length, 3.50 mm height, matte tin-plated leads, RoHS-compliant "Green" compound (94V-0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED anode - requires current-limiting resistor when driven from 3.3 V, 5 V, or 24 V logic sources |
| 2 | Cathode | LED cathode - connects to ground or low-side switch; polarity dot on package identifies Pin 1 |
| 3 | Emitter | Phototransistor emitter - typically tied to system ground on isolated side for common-emitter configuration |
| 4 | Collector | Phototransistor collector - pulled up to VCC_ISO via load resistor; output swings between VCC_ISO and VCE(SAT) ≤0.2 V |
Key Features
| Feature | Design Value |
|---|---|
| High CTR consistency | CTR rank D (50–600%) enables stable loop gain in voltage-mode SMPS feedback without external gain trimming |
| Reinforced isolation barrier | 5000 VRMS rating meets IEC 62368-1 basic/reinforced insulation requirements for primary-to-secondary separation |
| Extended temperature operation | −55°C to +110°C range eliminates need for thermal derating in industrial enclosures or engine compartments |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and JEDEC JS709E - compatible with lead-free reflow profiles and environmentally regulated markets |
| Low CTR degradation | Guaranteed minimum CTR maintained over 10-year lifetime at 105°C - critical for long-lifecycle power supplies |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar phototransistor optocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP183(TPL,E | CTR min 50%, same MDIP-4 package, but only UL certified (no VDE); tR/tF = 18/18 µs | Lacks VDE EN IEC 60747-5-5 - unsuitable for EU medical or industrial equipment requiring dual-certification | Select when UL-only approval suffices and cost sensitivity outweighs dual-certification requirement |
| PC817XNIP0X | CTR min 80%, DIP-4 (not MDIP-4); 5000 VRMS isolation; same −55°C to +110°C range | Longer creepage (9.0 mm vs. 7.62 mm) and larger footprint - may not fit space-constrained PCB layouts | Choose when higher baseline CTR improves noise immunity in low-IF designs, and board real estate permits DIP-4 spacing |
Compared with TLP183(TPL,E and PC817XNIP0X, DPC817W-D-TU uniquely combines MDIP-4 compactness, VDE+UL dual certification, and wide CTR range - making it optimal for space-limited, globally certified industrial power and control systems.

FAQ
What is the CTR rank designation for DPC817W-D-TU?
The "D" suffix indicates the CTR rank is 50–600% at IF = 5 mA and VCE = 5 V, measured at +25°C. This broad range accommodates applications needing either high sensitivity (e.g., low-drive microcontrollers) or robustness against CTR degradation over time and temperature.
Does DPC817W-D-TU support analog linear operation?
Yes - its phototransistor output exhibits predictable collector current vs. forward current linearity across 1–20 mA input range, enabling use in analog feedback paths such as voltage-mode SMPS error amplifiers without external compensation for nonlinearity.
Can DPC817W-D-TU replace DPC817W-A-TU in existing designs?
Yes, with functional equivalence: both share identical MDIP-4 package, pinout, isolation rating, and temperature range. The "D" rank offers wider CTR tolerance (50–600% vs. 80–160% for "A"), providing greater margin for aging and temperature drift in long-life applications.
What safety certifications apply to DPC817W-D-TU?
DPC817W-D-TU carries UL 1577 recognition (file E525887), CQC GB 4943.1-2022 certification, and VDE EN IEC 60747-5-5 approval - confirming compliance with global reinforced insulation standards for end-equipment safety certification.
