Product details
Overview
DPC817L-D-TR-V from Diodes Incorporated is a high-isolation, single-channel phototransistor coupler in SLM-4 package, featuring 5000 VRMS isolation voltage, CTR ≥50% at IF=5mA/VCE=5V, VCEO=35V, and operation from −55°C to +110°C. It provides galvanic signal transfer in industrial power supplies, PLC I/O modules, and AC mains monitoring circuits where safety-rated insulation and temperature resilience are required.
For engineers reviewing the DPC817L-D-TR-V datasheet, DPC817L-D-TR-V pinout, DPC817L-D-TR-V application, or DPC817L-D-TR-V equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in isolated feedback and digital input conditioning, and confirmed alternative parts with documented CTR and safety certification differences.
Technical Context
The DPC817L-D-TR-V integrates an AlGaAs infrared LED optically coupled to a silicon NPN phototransistor. Its internal structure enables DC–80 kHz signal transmission with 18 µs rise/fall times (RL = 100 Ω) and maintains CTR stability across −55°C to +110°C ambient range.
It meets reinforced insulation requirements per UL1577 and VDE EN IEC 60747-5-5, with isolation barrier rated for 5000 VRMS for 1 minute and isolation resistance ≥5×10¹⁰ Ω. The device operates with forward current up to 60 mA and collector current up to 50 mA, supporting both linear and saturated switching modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar phototransistor coupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PC817XNIP0X | CTR min 80% (Rank X), same 5000 VRMS isolation, but no VDE certification; UL1577 only. | Lacks VDE EN IEC 60747-5-5 approval - unsuitable for EU medical or industrial equipment requiring dual-certified isolation. | Select when cost sensitivity outweighs regional safety certification requirements and CTR margin >80% is acceptable. |
| TLP183(GB-TP,F) | Higher CTR (100–600%), same 5000 VRMS, VDE certified, but TO-220-4L package (through-hole). | Through-hole mounting limits PCB density; larger footprint incompatible with space-constrained SMT layouts. | Choose for legacy through-hole designs or where higher CTR improves noise immunity in low-IF sensing applications. |
Compared with PC817XNIP0X and TLP183(GB-TP,F), DPC817L-D-TR-V uniquely combines SLM-4 SMT compatibility, VDE+UL dual certification, and guaranteed 50% CTR minimum-making it optimal for new industrial designs requiring compact, globally certified isolation.

FAQ
What safety certifications does DPC817L-D-TR-V hold?
DPC817L-D-TR-V is certified to UL1577 (5000 VRMS, 1 minute), VDE EN IEC 60747-5-5 (reinforced insulation), and CQC GB 4943.1-2022. These approvals cover dielectric strength, partial discharge, and creepage/clearance requirements for end-equipment safety compliance in North America, Europe, and China.
Can DPC817L-D-TR-V replace DPC817S-A-TR in SL-4 footprint designs?
No-DPC817L-D-TR-V uses SLM-4 (11.88 mm body width), while DPC817S-A-TR uses SL-4 (10.16 mm). Their pad layouts differ: SLM-4 requires C1 = 10.86 mm vs. SL-4's C1 = 9.22 mm. Mechanical interference and solder joint reliability would be compromised without PCB redesign.
What is the meaning of "D" in DPC817L-D-TR-V's part number?
The "D" denotes the Current Transfer Ratio (CTR) rank, specifying a minimum CTR of 50% at IF = 5 mA and VCE = 5 V. Unlike A/B/C/X/Y ranks (which define tighter CTR bands), "D" is the base-grade option covering the full 50–600% datasheet range, optimized for cost-sensitive industrial applications where wide CTR tolerance is acceptable.
Does DPC817L-D-TR-V support linear analog signal transmission?
Yes-its phototransistor output exhibits predictable CTR vs. IF linearity (±15% deviation over 1–20 mA input range per Fig.3), enabling use in analog feedback loops. However, temperature-induced CTR drift (±30% over −55°C to +110°C per Fig.5) requires compensation in precision applications; it is best suited for moderate-accuracy regulation or digital threshold detection.
