Diodes Incorporated DPC817S-D-TR-V

Overview

DPC817S-D-TR-V from Diodes Incorporated is a high-isolation, single-channel phototransistor output optocoupler in SL-4 surface-mount package, featuring 5000 VRMS input-output isolation voltage, minimum 50% current transfer ratio (CTR) at IF = 5 mA / VCE = 5 V, and -55°C to +110°C operating temperature range. It provides galvanic signal isolation in industrial power supply feedback loops, PLC I/O modules, and AC mains-sensing circuits.

For engineers reviewing the DPC817S-D-TR-V datasheet, DPC817S-D-TR-V pinout, DPC817S-D-TR-V application, or DPC817S-D-TR-V equivalent, this page delivers verified electrical specs, safety certifications (UL1577, VDE EN IEC 60747-5-5), CTR rank confirmation (D = 50–600%), SL-4 footprint details, and real-world isolation use cases - all validated against Diodes DS45855 Rev. 5-2.

Technical Context

This optocoupler integrates an AlGaAs infrared LED emitter coupled to a silicon NPN phototransistor detector in a single molded plastic package. Its internal structure enables DC-to-80 kHz signal transmission with 18 µs rise/fall times and <0.2 V collector-emitter saturation voltage under rated drive conditions.

The device operates with bidirectional isolation: input side handles up to 60 mA forward current and 6 V reverse voltage, while output side supports 35 V VCEO, 50 mA IC, and withstands 5000 VRMS for ≥1 minute per UL/VDE standards. CTR variation across temperature (-40°C to +100°C) is characterized and specified in Fig.5 of the datasheet.

FAQ

What safety certifications does DPC817S-D-TR-V hold?

DPC817S-D-TR-V is certified to UL1577 (5000 VRMS, 1 minute) and VDE EN IEC 60747-5-5 (5000 VRMS, 1 minute), with full documentation in Diodes' Certificate of Compliance CQC 4943.1-2022. The "V" suffix explicitly denotes VDE qualification, confirmed in ordering information tables on pages 2–3 of DS45855 Rev. 5-2.

What does the "D" in DPC817S-D-TR-V signify?

The "D" denotes the Current Transfer Ratio (CTR) rank, specifying a guaranteed CTR range of 50% to 600% at IF = 5 mA and VCE = 5 V, per the Rank Table on page 3 of DS45855 Rev. 5-2. This is the broadest CTR bin offered in the DPC817S series, providing maximum design flexibility for varying LED drive conditions and aging compensation.

Can DPC817S-D-TR-V replace DPC817S-A-TR-V in existing designs?

Yes - both share identical SL-4 package, pinout, isolation rating, and temperature range. The only difference is CTR range: A-rank guarantees 80–160%, while D-rank covers 50–600%. Substitution is electrically safe but may require verification of minimum CTR margin in low-IF or high-temperature operation due to the wider D-rank spread.

Is DPC817S-D-TR-V suitable for automotive applications?

No - DPC817S-D-TR-V is not AEC-Q100 qualified. Diodes explicitly states in the datasheet that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing - none of which apply to this part. For automotive use, contact Diodes for AEC-Q101-qualified alternatives such as the APD3110 series.
