Product details
Overview
DPC817D-C-TU-V from Diodes Incorporated is a high-reliability, VDE-certified photocoupler with 200–400% current transfer ratio (CTR) at IF = 5 mA and VCE = 5 V, 35 V C-E breakdown voltage, and 5000 VRMS input-output isolation. It operates across –55°C to +110°C and is used in feedback loops of isolated DC-DC converters, I/O signal isolation in industrial PLCs, and safety-critical power supply monitoring circuits.
For engineers reviewing the DPC817D-C-TU-V datasheet, DPC817D-C-TU-V pinout, DPC817D-C-TU-V application, or DPC817D-C-TU-V equivalent, key selection criteria include CTR rank C (200–400%), VDE EN IEC 60747-5-5 certification, DIP-4 package compatibility, and guaranteed operation up to +110°C ambient.
Technical Context
This optocoupler integrates a GaAs infrared LED emitter and a silicon NPN phototransistor in a single DIP-4 package. Its internal structure enables galvanic isolation between input and output sides, with CTR defined as IC/IF × 100% under standardized test conditions (IF = 5 mA, VCE = 5 V).
The device supports linear-mode and switch-mode operation: saturation voltage VCE(SAT) ≤ 0.2 V at IF = 20 mA / IC = 1 mA confirms robust switching performance, while cutoff frequency fC ≥ 80 kHz and response times tR/tF ≤ 18 µs support medium-speed digital signal isolation in motor control gate drivers and isolated UART interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CTR Range | 200–400% at IF = 5 mA, VCE = 5 V - ensures reliable transistor turn-on across temperature and aging, reducing need for external gain compensation |
| Isolation Voltage | 5000 VRMS - meets reinforced insulation requirements for IEC 62368-1 and UL 62368-1 in AC/DC power supplies |
| VCEO | 35 V - supports use in 24 V industrial control outputs and auxiliary bias rails without external collector clamping |
| Operating Temp | –55°C to +110°C - qualified for under-hood automotive modules and outdoor telecom equipment |
| VCE(SAT) | ≤ 0.2 V at IF = 20 mA, IC = 1 mA - minimizes power loss in saturated switching applications like relay drivers |
| fC | ≥ 80 kHz - enables clean isolation of PWM signals up to ~40 kHz with <3 dB attenuation |
| Response Time | tR/tF ≤ 18 µs - supports 25 kHz digital signal transmission with <10% pulse distortion |
Pinout & Package
Package: DIP-4 (Dual In-line Package, 0.3″ wide), molded green plastic, UL 94V-0 rated, matte tin-plated leads, pin 1 marked with polarity dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED anode input - requires series resistor to limit IF to ≤60 mA; polarity dot identifies this pin |
| 2 | Cathode | LED cathode return - connects to ground or low-side switch for LED drive |
| 3 | Emitter | Phototransistor emitter output - typically grounded to enable common-emitter switching configuration |
| 4 | Collector | Phototransistor collector output - connects to pull-up resistor and load; delivers isolated logic-level or analog current output |
Key Features
| Feature | Design Value |
|---|---|
| VDE EN IEC 60747-5-5 certified | Validated isolation barrier per international safety standard - eliminates need for system-level requalification in medical and industrial end-equipment |
| CTR Rank C (200–400%) | Narrower distribution than Rank A/B - improves consistency in closed-loop feedback designs without trimming resistors |
| Lead-free & Halogen-free | RoHS 3 compliant with Br+Cl <1500 ppm, Sb <1000 ppm - satisfies IPC-1752A material declaration and automotive PPAP requirements |
| Moisture Sensitivity Level 1 | No bake required before reflow - compatible with standard SMT assembly lines without process modification |
| High VISO (5000 VRMS) | Withstands 1.5× working voltage of 250 VAC systems - supports Class II insulation in offline SMPS designs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar photocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP281-4(GB-TP,F) | Quad-channel, 5000 VRMS, CTR 50–600%, but only UL/cUL certified (no VDE) | Lacks VDE EN IEC 60747-5-5 - unsuitable for EU medical or industrial safety approvals requiring VDE | Select when multi-channel integration reduces board area and VDE is not mandated |
| PC817X3NIP0X | Single-channel, 5000 VRMS, CTR 300–600%, VDE certified, but only rated to +100°C (vs. +110°C) | Lower max operating temperature limits use in high-ambient environments like engine control units | Select when higher CTR ceiling is needed and ambient stays ≤+100°C |
Compared with TLP281-4 and PC817X3NIP0X, DPC817D-C-TU-V uniquely combines VDE certification, +110°C operation, and tightly binned CTR (200–400%) - making it optimal for safety-critical, high-temperature industrial feedback systems where long-term CTR stability is mandatory.

FAQ
What safety certifications does DPC817D-C-TU-V hold?
DPC817D-C-TU-V is certified to UL 1577 (5000 VRMS), CQC GB 4943.1-2022, and VDE EN IEC 60747-5-5. The "-V" suffix explicitly denotes VDE certification, confirming compliance with reinforced insulation requirements for industrial and medical applications per IEC 62368-1 and IEC 60601-1.
How does CTR Rank C (200–400%) impact circuit design?
CTR Rank C guarantees minimum 200% current transfer at IF = 5 mA and VCE = 5 V, enabling robust saturation of the output phototransistor without oversized input drive. Its upper bound of 400% avoids excessive gain that could cause oscillation in feedback loops, simplifying compensation in SMPS designs.
Can DPC817D-C-TU-V replace older DPC817 variants in existing designs?
Yes - DPC817D-C-TU-V shares identical DIP-4 footprint, pinout, and absolute maximum ratings with other DPC817D-TU variants. Only CTR range differs (200–400% vs. 80–160% for Rank A); redesign is unnecessary unless legacy circuits rely on lower CTR for intentional gain limiting.
What is the recommended solder profile for DPC817D-C-TU-V?
The device is MSL Level 1 and rated for peak reflow temperature of +260°C. Standard IPC/JEDEC J-STD-020-compliant lead-free profiles apply: ramp-to-spike ≤3°C/s, time above 217°C = 60–150 s, peak = 235–245°C. No pre-bake is required due to moisture sensitivity level 1 classification.
