Product details
Overview
DPC817L-A-TR-V from Diodes Incorporated is a single-channel phototransistor-based optocoupler in SLM-4 surface-mount package, providing 5000 VRMS input-output isolation, CTR ≥80% at IF = 5 mA / VCE = 5 V, and operation from –55°C to +110°C. It isolates digital control signals in industrial PLC I/O modules, AC mains-sensed power supply feedback loops, and isolated gate drive interfaces for MOSFETs.
For engineers reviewing the DPC817L-A-TR-V datasheet, DPC817L-A-TR-V pinout, DPC817L-A-TR-V application, or DPC817L-A-TR-V equivalent, key selection criteria include guaranteed CTR rank A (80–160%), VDE-certified isolation, SLM-4 footprint compatibility with high-density PCB layouts, and verified performance under extended temperature cycling.
Technical Context
This optocoupler integrates an AlGaAs infrared LED emitter coupled to a silicon NPN phototransistor output stage. Its internal structure enables galvanic signal transfer without electrical continuity, supporting bidirectional logic-level interfacing across isolated domains.
The device meets VDE EN IEC 60747-5-5 and UL1577 safety standards, with isolation barrier rated for 5000 VRMS for 1 minute and isolation resistance ≥5×10¹⁰ Ω. Response time is ≤18 µs (rise/fall) into 100 Ω load, enabling reliable switching up to ~80 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5000 VRMS - Withstands sustained AC voltage stress between input and output for safety-critical isolation barriers. |
| CTR (Min) | 80% at IF = 5 mA, VCE = 5 V - Ensures sufficient output current gain for robust logic-level transmission across wide temperature range. |
| VCEO | 35 V - Supports collector supply up to 35 V, suitable for 24 V industrial control bus interfacing. |
| Operating Temp | –55°C to +110°C - Validated for use in automotive engine compartments and industrial motor drives without derating. |
| Response Time | ≤18 µs (tR/tF) - Enables clean digital signal transfer at frequencies up to 80 kHz in feedback and status monitoring circuits. |
| Package | SLM-4 - Surface-mount, 4-pin, gull-wing leadform with 2.54 mm pitch; optimized for automated assembly and thermal reliability. |
| Moisture Sensitivity | Level 1 per J-STD-020 - No bake requirement prior to reflow; compatible with standard Pb-free soldering profiles. |
Pinout & Package
SLM-4 is a 4-pin surface-mount package with gull-wing leads, 2.54 mm pitch, and 11.50–12.10 mm body width. Pin 1 is marked by dot; leads are matte tin-plated and solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | LED anode | Positive input for IR LED; requires series resistor to limit IF ≤60 mA (max rating). |
| 2 (Cathode) | LED cathode | Return path for LED current; polarity-sensitive-reverse connection blocks emission. |
| 3 (Emitter) | Phototransistor emitter | Common reference node for output stage; tied to system ground on isolated side. |
| 4 (Collector) | Phototransistor collector | Active output node; pulled high via external resistor to provide logic-high when LED off. |
Key Features
| Feature | Design Value |
|---|---|
| VDE EN IEC 60747-5-5 certification | Validated isolation barrier compliance for European industrial safety requirements. |
| CTR Rank A (80–160%) | Guaranteed minimum gain ensures stable switching margin across production lots and temperature extremes. |
| Lead-free, halogen-free, RoHS 3 compliant | Meets EU Directive 2015/863/EU with Br+Cl <1500 ppm and Sb <1000 ppm - supports green manufacturing. |
| High BVCEO (35 V) | Enables direct interface with 24 V DC control rails without external level-shifting components. |
| Low VCE(SAT) (0.2 V max) | Reduces output-stage power loss and improves noise immunity in saturated-switch applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar optocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP185(GB-TP,F) | CTR min 100% (IF=5mA), VDE-certified, same SLM-4 package but higher CTR binning and tighter VCE(SAT) spec (0.1 V max). | Preferred where higher gain margin is needed for marginal drive conditions or low-VCC logic interfaces. | Select TLP185 if CTR >100% is required to ensure saturation under worst-case aging and temperature drift. |
| PC817XNIP0X | Non-VDE version; same CTR rank A, DIP-4 through-hole package, no VDE marking, lower isolation test duration (1 sec vs. 1 min). | Suitable for cost-sensitive consumer-grade designs lacking formal safety certification requirements. | Choose PC817XNIP0X only for non-safety-critical applications where regulatory approval is not mandated. |
Compared with TLP185(GB-TP,F), DPC817L-A-TR-V offers lower CTR but broader temperature qualification (–55°C to +110°C vs. –55°C to +100°C) and identical VDE certification; versus PC817XNIP0X, it adds mandatory VDE compliance and extended thermal endurance for industrial deployment.

FAQ
What safety certifications does DPC817L-A-TR-V hold?
DPC817L-A-TR-V is certified to UL1577 (5000 VRMS, 1 minute) and VDE EN IEC 60747-5-5 (reinforced insulation). The "V" suffix explicitly denotes VDE-compliant units, validated for dielectric strength, partial discharge, and temperature cycling per Clause 7.2 and Annex A of the standard.
Can DPC817L-A-TR-V replace DPC817S-A-TR in existing designs?
Yes, with mechanical adaptation: both share identical electrical specs and CTR rank A, but DPC817L-A-TR-V uses SLM-4 (wider 11.88 mm body), whereas DPC817S-A-TR uses SL-4 (10.16 mm). Pad layout differs-SLM-4 requires C1 = 10.86 mm vs. SL-4's 9.22 mm-and must be verified against IPC-7351B land patterns.
What is the maximum recommended forward current for continuous operation?
The absolute maximum rated forward current is 60 mA, but Diodes specifies 5 mA as the standard test condition for CTR. For continuous operation, IF ≤20 mA is recommended to maintain CTR stability and lifetime; derating to 10 mA is advised for >10-year reliability in 85°C ambient environments.
Does DPC817L-A-TR-V support linear analog operation?
Yes-its phototransistor output operates in active and saturation regions. When biased with constant collector resistor and VCE ≥2 V, it delivers proportional collector current to LED drive current, enabling analog feedback in SMPS circuits, though CTR nonlinearity (±15% typical) must be calibrated in closed-loop designs.
