Overview
The DPC817S-C-TR-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an SMD/SMT installation style in an SL-4 package. The device provides 5000 Vrms insulation voltage and utilizes a phototransistor output type. Key electrical parameters include a minimum current transfer ratio of 130% and a maximum of 260%. The forward current is rated at 5 mA with a forward voltage of 1.25 V. Maximum collector-emitter voltage is 35 V, maximum collector current is 30 mA, and the maximum collector-emitter saturation voltage is 200 mV.
Feature Summary
- Provides galvanic isolation between input and output circuits via optical transmission.
- Features a compact surface-mount SL-4 package for automated assembly.
- Delivers high current transfer ratio performance for efficient signal coupling.
Applications
- Signal isolation in industrial control systems
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix 'C' against the manufacturer's official datasheet to confirm the exact Current Transfer Ratio binning requirements. Ensure the SL-4 package dimensions match the target PCB footprint. Confirm RoHS compliance status through the latest product documentation before finalizing procurement specifications.
Selection Notes
Select this component when a standard NPN phototransistor output with moderate CTR range is required. Compare the 35 V collector-emitter voltage rating against system load requirements. Evaluate the 5 mA forward current drive capability against available microcontroller GPIO outputs to ensure sufficient margin for reliable switching operation.
Part Context
This part belongs to the DPC817 series of transistor output optocouplers from Diodes Incorporated. The series offers various CTR bins (B, C, Y) to accommodate different gain requirements while maintaining consistent physical packaging and basic electrical characteristics such as insulation voltage and package type.
Replacement Considerations
Check for direct substitutes within the same family, such as DPC817S-B-TR-V or DPC817S-Y-TR-V, which share identical pinouts but differ in CTR specifications. Verify that alternative components meet the 5000 Vrms isolation requirement and SL-4 package constraints.
