Product details
Overview
DPC817D-B-TU-V from Diodes Incorporated is a high-isolation, single-channel phototransistor output optocoupler in DIP-4 package, featuring 130–260% CTR at IF = 5 mA/VCE = 5 V, 5000 VRMS isolation voltage, and -55°C to +110°C operating range. It provides galvanic signal transfer between microcontroller I/O and AC mains-controlled triac drivers in industrial PLC input modules.
For engineers reviewing the DPC817D-B-TU-V datasheet, DPC817D-B-TU-V pinout, DPC817D-B-TU-V application, or DPC817D-B-TU-V equivalent, key selection criteria include CTR rank B (130–260%), VDE EN IEC 60747-5-5 safety certification, collector-emitter saturation voltage ≤0.2 V, and compatibility with 5 V logic-level drive circuits.
Technical Context
This optocoupler integrates an AlGaAs infrared LED emitter coupled to a silicon NPN phototransistor output stage. Its internal structure enables DC–80 kHz signal transmission with 18 µs rise/fall times under RL = 100 Ω and VCE = 2 V conditions.
The device operates with forward current up to 60 mA and supports collector-emitter voltages up to 35 V. Its 5×10¹⁰ Ω minimum isolation resistance and 0.6–1 pF floating capacitance ensure low noise coupling across the isolation barrier in high-speed digital interface applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CTR Range | 130–260% at IF = 5 mA, VCE = 5 V - ensures reliable switching margin for 3.3 V/5 V MCU outputs driving triac gate circuits |
| Isolation Voltage | 5000 VRMS - meets reinforced insulation requirements for industrial AC line sensing and motor control interfaces |
| VCE(SAT) | ≤0.2 V at IF = 20 mA, IC = 1 mA - minimizes power loss and heat generation in output-stage pull-down configurations |
| fC | 80 kHz (-3 dB) - supports PWM feedback loop closure in isolated SMPS error amplifiers |
| tR/tF | ≤18 µs each - enables clean edge transmission for serial communication isolation up to 20 kbps |
| BVCEO | 35 V - allows direct interfacing with 24 VDC control rails without external collector resistors |
| RISO | ≥5×10¹⁰ Ω - maintains long-term reliability in humid or contaminated industrial environments |
Pinout & Package
Package: DIP-4 (Dual In-line Package, 0.300" wide), molded plastic body with matte tin-plated leads, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED anode requiring series resistor for current limiting from 3.3 V/5 V logic sources |
| 2 | Cathode | LED cathode - connects to ground or active-low driver for optical activation |
| 3 | Emitter | Phototransistor emitter - typically grounded to enable common-emitter switching configuration |
| 4 | Collector | Phototransistor collector - pulled up to 5 V/24 V rail via load resistor for logic-level output |
Key Features
| Feature | Design Value |

| Operating temperature: –55°C to +110°C | Supports deployment in uncontrolled ambient environments such as outdoor motor drives and railway signaling cabinets |
| 5000 VRMS isolation | Enables safe interface between SELV (Safety Extra-Low Voltage) logic domains and hazardous AC mains circuits |
Applications
| Industrial PLC Input Isolation | AC Mains Zero-Crossing Detection |

IC Role / Device Role / Timing Role: Fail-safe logic-level isolator verifying dual-channel interlock signals before enabling high-power IGBT gates. Use Value: Guarantees <5000 VRMS withstand during fault events, preventing inadvertent activation under ESD or surge stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar phototransistor-output optocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP185(GB-TP,F) | CTR 100–300%, same DIP-4 package, but lacks VDE certification and has higher VCE(SAT) (0.3 V max) | Acceptable for non-safety-certified consumer products; unsuitable where reinforced insulation documentation is required | Select when cost is prioritized over safety certification and higher saturation voltage is tolerable |
| PC817XNNSZ0F | CTR 130–260% (same rank), but rated only to +100°C and certified to UL1577 only (no VDE) | Valid for commercial temperature range designs; not qualified for extended industrial ambient operation | Choose if operating environment stays below +100°C and VDE documentation is unnecessary |
Compared with TLP185(GB-TP,F) and PC817XNNSZ0F, DPC817D-B-TU-V uniquely combines VDE EN IEC 60747-5-5 certification, +110°C operation, and guaranteed CTR rank B - making it the only option qualified for safety-critical industrial control systems requiring full regulatory traceability and extended thermal margin.

FAQ
What is the maximum recommended forward current for continuous operation?
The absolute maximum forward current is 60 mA, but Diodes specifies 5 mA as the standard test condition for CTR characterization. For reliable long-term operation, continuous IF should be limited to ≤20 mA with appropriate derating above +70°C ambient per the datasheet's thermal curves.
Does DPC817D-B-TU-V support linear analog signal transmission?
Yes - its phototransistor output exhibits approximately linear current transfer over IF = 1–10 mA at fixed VCE, enabling use in analog feedback loops. However, CTR variation with temperature and aging must be compensated in precision applications; typical linearity error is ±5% across the specified operating range.
How does the "-V" suffix affect safety certification?
The "-V" suffix denotes VDE EN IEC 60747-5-5 certification, which validates the device's construction, creepage/clearance distances, and partial discharge performance beyond basic UL1577 approval. This enables use in applications requiring reinforced insulation per IEC 61800-5-1 and IEC 62109 standards.
Can DPC817D-B-TU-V replace older DPC817A variants in existing designs?
Yes - it shares identical DIP-4 footprint, pinout, and absolute maximum ratings. The higher CTR rank B improves noise immunity and reduces required input drive current, but may necessitate verification of output stage loading to avoid excessive collector current in legacy circuits originally designed for lower CTR parts.
