Overview
The DPC817L-Y-TR is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an SLM-4 surface-mount package and provides 5000 VRMS isolation voltage. Key electrical parameters include a collector-emitter breakdown voltage of 35V, a maximum collector current of 30mA, and a forward voltage of 1.25V at 5mA forward current. The device offers a current transfer ratio ranging from 150% to 300%. This component is designed for applications requiring reliable signal transmission with high insulation capabilities in a compact form factor.
Feature Summary
- Provides galvanic isolation between input and output circuits using a phototransistor configuration.
- Features a compact SLM-4 surface-mount package suitable for automated assembly processes.
- Delivers high insulation voltage capability for safety-critical signal transmission.
Applications
- Signal isolation in industrial control systems
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix 'Y' against the manufacturer's latest datasheet to confirm binning or performance tier specifications. Ensure the SLM-4 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through official documentation before finalizing procurement decisions.
Selection Notes
Select this component when a single channel with moderate current transfer ratio is required. The 35V output voltage rating suits low-voltage logic interfaces. Consider the 150-300% CTR range for standard switching applications. Verify thermal management needs based on the 5mA typical forward current operation.
Part Context
This part belongs to the DPC817L series of transistor output optocouplers. The series includes variants such as DPC817L-A-TR and DPC817L-C-TR, which differ primarily in current transfer ratio bins. The DPC817L-Y-TR represents a specific performance bin within this family, offering defined CTR limits for consistent circuit behavior.
Replacement Considerations
Direct substitutes may include DPC817L-A-TR or DPC817L-C-TR if their respective CTR ranges align with design tolerances. Verify pinout compatibility and package integrity before substitution. Consult Diodes Incorporated for qualified replacement lists.
