Overview
The DPC817S-X-TR-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an SL-4 surface-mount package and provides 5000 Vrms isolation voltage. The device utilizes an NPN phototransistor output with a collector-emitter voltage rating of 35 V and a maximum collector current of 30 mA. The forward current is specified at 5 mA, with a forward voltage of 1.25 V. The current transfer ratio ranges from 100% to 200%. The component is supplied in tape and reel packaging with a quantity of 2000 units.
Feature Summary
- Provides electrical isolation via infrared LED and phototransistor pair
- Designed for surface-mount assembly using SL-4 package
- Offers high isolation voltage capability for signal integrity
Applications
- General-purpose signal isolation in industrial control systems
- Interface circuits between microcontrollers and power stages
- Signal transmission across isolated ground domains
Procurement Notes
Verify the specific CTR bin (X) against design requirements, as performance varies within the 100%-200% range. Confirm the SL-4 footprint matches the PCB layout. Ensure the 5000 Vrms isolation rating meets safety standards for the target application environment. Check RoHS compliance documentation if required by project specifications.
Selection Notes
Select this component when a standard 4-pin SMD optocoupler is needed for low-speed digital isolation. The 35 V collector voltage suits low-voltage logic interfaces. Compare against DPC817S-A or DPC817S-B variants if different CTR bins are preferred. Ensure the 5 mA drive current aligns with the source circuit capabilities.
Part Context
This part belongs to the DPC817 series of transistor output optocouplers from Diodes Incorporated. The series offers various CTR bins and packaging options. The DPC817S-X variant specifically denotes the X bin for current transfer ratio. It is part of a broader portfolio including logic output and high-voltage transistor output devices.
Replacement Considerations
DPC817S-A-TR-V and DPC817S-B-TR-V are alternative CTR bins within the same package family. Verify pinout compatibility and isolation voltage ratings before substitution. Other manufacturers' 4-SMD optocouplers may require schematic and layout adjustments.
