Product details
Overview
DPC817D-D-TU-V from Diodes Incorporated is a high-isolation, single-channel phototransistor output optocoupler in DIP-4 package, featuring 5000 VRMS isolation voltage, minimum 50% current transfer ratio (CTR) at IF = 5 mA / VCE = 5 V, and BVCEO of 35 V. It enables galvanic signal coupling in industrial power supplies, PLC I/O modules, and AC mains-sensed feedback circuits where safety-rated insulation and noise immunity are critical.
For engineers reviewing the DPC817D-D-TU-V datasheet, DPC817D-D-TU-V pinout, DPC817D-D-TU-V application, or DPC817D-D-TU-V equivalent, key selection criteria include CTR rank (D = 100–200%), VDE EN IEC 60747-5-5 certification, -55°C to +110°C operating range, and DIP-4 lead-form compatibility with legacy through-hole PCB layouts.
Technical Context
This optocoupler integrates an AlGaAs infrared LED emitter paired with a silicon NPN phototransistor detector in a single molded plastic body. Its internal structure provides unidirectional DC signal transfer across reinforced insulation barriers, with no internal base connection - enabling simplified biasing and predictable saturation behavior under load.
The device operates with forward input current (IF) up to 60 mA and supports collector-emitter voltages up to 35 V. Its 80 kHz cutoff frequency and ≤18 µs rise/fall times support medium-speed digital isolation (e.g., UART level-shifting, PWM feedback), while its 5×10¹⁰ Ω minimum isolation resistance ensures long-term reliability in humid or contaminated environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5000 VRMS - meets reinforced insulation requirements per UL1577 and VDE EN IEC 60747-5-5 for mains-connected equipment. |
| CTR (Min) | 50% at IF = 5 mA, VCE = 5 V - guarantees minimum output current drive capability for reliable logic-level detection across temperature. |
| BVCEO | 35 V - defines maximum allowable collector-emitter voltage during switching, suitable for 24 VDC control systems and flyback snubber interfaces. |
| Operating Temp | -55°C to +110°C - supports deployment in automotive engine bays, industrial motor drives, and outdoor power converters without derating. |
| Response Time | ≤18 µs (rise/fall) - enables accurate isolation of PWM signals up to ~30 kHz without significant duty-cycle distortion. |
| Isolation Resistance | ≥5×10¹⁰ Ω - ensures stable DC coupling performance over decades in high-humidity environments (e.g., HVAC controls). |
| Cutoff Frequency | 80 kHz - sets upper bandwidth limit for analog signal transmission; sufficient for feedback loop isolation in switch-mode power supplies. |
Pinout & Package
Package: DIP-4 (Dual In-line Package, 0.3" wide), lead pitch 2.54 mm, matte tin-plated leads, RoHS-compliant "Green" mold compound (UL 94V-0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED anode input; requires series resistor to limit IF to ≤60 mA; polarity marked by dot on package. |
| 2 | Cathode | LED cathode return; connects to ground or low-side switch; reverse voltage rating is 6 V. |
| 3 | Emitter | Phototransistor emitter output; typically tied to ground for common-emitter configuration. |
| 4 | Collector | Phototransistor collector output; pulled high via external load resistor to enable active-low switching or logic-level translation. |
Key Features
| Feature | Design Value |
|---|---|
| VDE-certified isolation | EN IEC 60747-5-5 compliance enables use in medical and industrial safety-critical systems requiring certified barrier integrity. |
| CTR Rank D (100–200%) | Guaranteed mid-range gain stability across production lots, reducing need for post-manufacture binning or calibration in feedback loops. |
| Lead-free & halogen-free | Meets RoHS 3 and JEDEC J-STD-020 Level 1 moisture sensitivity - supports lead-free reflow assembly without popcorn cracking risk. |
| High BVCEO (35 V) | Permits direct interface with 24 VDC control rails and flyback transformer auxiliary windings without external clamping diodes. |
| Wide temperature range | Operates reliably from cryogenic (-55°C) to high-heat (+110°C) environments, validated for extended life in sealed enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phototransistor-output optocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PC817XNIP0X | CTR min 80%, same DIP-4 package, but lacks VDE certification and rated only to 3750 VRMS isolation. | Suitable for non-safety-critical consumer electronics; not approved for industrial or medical mains isolation. | Select when cost sensitivity outweighs regulatory compliance requirements and system-level safety validation is not mandated. |
| TLP183(GB-TP,F) | CTR min 50%, VDE-certified, but uses SMD SO-4 package and has higher CTR variation (±30% vs ±25% for DPC817D-D-TU-V). | Requires PCB redesign for surface-mount assembly; better suited for space-constrained designs than legacy through-hole layouts. | Choose for new SMT-based platforms where board area is constrained and automated placement is preferred over manual DIP insertion. |
Compared with PC817XNIP0X and TLP183(GB-TP,F), DPC817D-D-TU-V delivers certified 5000 VRMS isolation in a proven DIP-4 form factor with tighter CTR tolerance - making it optimal for retrofitting safety-compliant upgrades into existing industrial hardware without layout changes.

FAQ
What is the CTR rank designation for DPC817D-D-TU-V?
The "D" in DPC817D-D-TU-V indicates CTR Rank D, specifying a guaranteed current transfer ratio of 100% to 200% at IF = 5 mA and VCE = 5 V. This mid-range bin offers improved consistency over lower-rank variants and reduces design margining needs in closed-loop feedback applications.
Does DPC817D-D-TU-V support AC input signals directly?
No - the input side contains only an LED, which conducts only in forward bias. To interface with AC signals, an external bridge rectifier or series diode must be added to ensure unidirectional current flow through Pin 1 and Pin 2. The device itself does not rectify or condition AC waveforms.
Can DPC817D-D-TU-V replace older PC817 variants in existing designs?
Yes, with verification of CTR rank and safety certification requirements. DPC817D-D-TU-V matches PC817's pinout and basic electrical specs but adds VDE EN IEC 60747-5-5 certification and tighter CTR control. Confirm that the target application requires or benefits from the enhanced isolation rating before substitution.
What is the significance of the "-V" suffix in DPC817D-D-TU-V?
The "-V" suffix denotes VDE certification compliance per EN IEC 60747-5-5. It appears only on units tested and qualified to this specific standard and is marked physically on the package with a "V" code. This distinguishes it from non-VDE versions like DPC817D-D-TU, which carry only UL1577 approval.
