Product details
Overview
DPC817L-C-TR-V from Diodes Incorporated is a high-isolation, CTR-rank-C phototransistor-based optocoupler in SLM-4 surface-mount package, featuring 200–400% current transfer ratio at IF = 5 mA/VCE = 5 V, 5000 VRMS input-output isolation voltage, and operation from −55°C to +110°C - deployed in industrial PLC I/O modules for galvanic signal level shifting.
For engineers reviewing the DPC817L-C-TR-V datasheet, DPC817L-C-TR-V pinout, DPC817L-C-TR-V application, or DPC817L-C-TR-V equivalent, key selection criteria include CTR consistency across temperature, UL/VDE safety certification status, creepage/clearance compliance in SLM-4 footprint, and saturation voltage under 0.2 V at IC = 1 mA.
Technical Context
This device integrates a GaAs infrared LED coupled to a silicon NPN phototransistor in a single-molded SLM-4 package. Its optical coupling enables bidirectional signal transmission across reinforced insulation barriers without electrical continuity.
The phototransistor output operates in linear or saturated mode depending on load and drive conditions; CTR rank C (200–400%) ensures predictable gain margin for feedback loop stability in isolated DC-DC converter regulation and microcontroller GPIO isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CTR (Min/Max) | 200% to 400% at IF = 5 mA, VCE = 5 V - guarantees sufficient output current drive for logic-level interfacing with margin over temperature. |
| VISO | 5000 VRMS - meets reinforced insulation requirements for industrial mains-connected equipment per IEC 62368-1. |
| VCEO | 35 V - supports collector supply up to 24 V systems with headroom for transient spikes. |
| VCE(SAT) | 0.1 V (typ), 0.2 V (max) at IF = 20 mA, IC = 1 mA - enables low-loss switching in digital isolation paths. |
| fC | 80 kHz (−3 dB) - suitable for PWM signal isolation up to 20 kHz with <1% distortion. |
| RISO | 5 × 1010 Ω (min) - ensures long-term insulation integrity in humid environments. |
| TOPR | −55°C to +110°C - qualified for extended-temperature industrial and automotive under-hood auxiliary circuits. |
Pinout & Package
SLM-4 surface-mount package: 4-pin, gull-wing leadform, 2.54 mm pitch, 11.50 mm × 7.32 mm body, 3.50 mm height, matte tin-plated leads, JEDEC-standard moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED anode - requires series resistor to limit forward current to ≤60 mA; polarity dot marked. |
| 2 | Cathode | LED cathode - connects to ground or low-side switch; reverse voltage rating 6 V. |
| 3 | Emitter | Phototransistor emitter - typically tied to system ground for common-emitter configuration. |
| 4 | Collector | Phototransistor collector - output node pulled high via external load resistor; drives logic inputs or MOSFET gates. |
Key Features

|---|---|
| VDE EN IEC 60747-5-5 + UL 1577 certified | Validated reinforced insulation barrier enabling single-component isolation in safety-critical control loops. |
| CTR rank C (200–400%) | Reduces need for post-isolation gain stages in analog feedback paths and improves noise immunity in noisy factory environments. |
| SLM-4 footprint with 11.88 mm E dimension | Provides ≥8.0 mm creepage distance - exceeds IPC-2221B Class B requirements for 300 V working voltage. |
| Lead-free, halogen-free, antimony-free "Green" compound | Complies with RoHS 3 (2015/863/EU) and automotive PPAP material declarations without compromising thermal cycling reliability. |
| Response time tR/tF ≤ 18 µs | Supports reliable 25 kHz digital signal isolation (e.g., UART, SPI clock enable) with minimal pulse width distortion. |
Applications
| Industrial PLC Digital Input Module | Isolated DC-DC Converter Feedback |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phototransistor optocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP185(GB-TP,F) | CTR 100–300%, VISO = 5000 VRMS, same SLM-4 package but Toshiba-marked tape/reel packaging. | Limited to 100–300% CTR range - less margin for aging drift in closed-loop feedback designs. | Select when sourcing flexibility across multiple franchises is prioritized over CTR headroom. |
| PC817X3NIP0X | CTR 200–400%, VISO = 5000 VRMS, SL-4 package (9.22 mm E), no VDE marking - only UL 1577 certified. | Shorter creepage (7.32 mm vs. 8.0+ mm) - insufficient for 2× MOPP medical or 300 V industrial working voltage. | Choose for cost-sensitive consumer-grade isolated interfaces where VDE certification is not mandated. |
Compared with TLP185(GB-TP,F) and PC817X3NIP0X, DPC817L-C-TR-V delivers higher guaranteed CTR consistency and full VDE EN IEC 60747-5-5 compliance in a longer creepage SLM-4 package - making it preferred for safety-critical industrial and medical feedback paths requiring long-term reliability.

FAQ
What safety certifications does DPC817L-C-TR-V hold?
DPC817L-C-TR-V is certified to UL 1577 (5000 VRMS) and VDE EN IEC 60747-5-5 (reinforced insulation), with full documentation traceable to Diodes' Certificate No. 4943.1-2022. It carries the "V" suffix marking indicating VDE qualification on the device body and reel label.
How does CTR rank C affect circuit design?
CTR rank C guarantees 200–400% current transfer at IF = 5 mA/VCE = 5 V, allowing designers to size the LED current-limiting resistor for worst-case CTR (200%) while retaining margin for aging and temperature drift - reducing need for trimming or feedback compensation.
Can DPC817L-C-TR-V replace DPC817S-C-TR-V in PCB layout?
No - DPC817L-C-TR-V uses SLM-4 (11.88 mm E dimension), while DPC817S-C-TR-V uses SL-4 (10.16 mm E). The SLM-4 has longer creepage and different pad layout (C1 = 10.86 mm vs. 9.22 mm); direct replacement requires board revision to accommodate larger body and adjusted solder pads.
What is the maximum recommended LED forward current?
The absolute maximum forward current is 60 mA, but continuous operation above 20 mA accelerates LED degradation. Diodes specifies 5 mA as the standard test condition for CTR; for 100% lifetime reliability, design for IF ≤ 20 mA with derating per Figure 3 in DS45855 Rev. 5-2.
