DPC816S-C-TR

Overview

The DPC816S-C-TR is a single-channel transistor output optocoupler from Diodes Incorporated, housed in an SL-4 surface-mount package. It features a phototransistor output with a collector-emitter voltage of 80 V and a maximum collector current of 30 mA. The device provides 5000 VRMS insulation voltage for signal isolation. Key electrical parameters include a forward current of 5 mA, a forward voltage of 1.25 V, and a collector-emitter saturation voltage of 200 mV. The C-grade variant offers a current transfer ratio ranging from 200% to 400%, with rise and fall times specified at 18 µs.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits via optical transmission.
• Features a phototransistor output stage suitable for digital signal switching applications.
• Utilizes a compact SMD package design for automated surface-mount assembly processes.

Applications

• Signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic families
• Power supply feedback loops requiring galvanic separation

Procurement Notes

Verify the specific grade suffix (C) against project requirements to ensure the correct Current Transfer Ratio range is met. Confirm that the SL-4 package dimensions align with the PCB footprint. Check RoHS compliance status as indicated in official documentation. Ensure the tape-and-reel quantity matches production line handling capabilities. Validate supplier authenticity through authorized distribution channels.

Selection Notes

Select this component when a moderate speed response with 18 µs transition times is sufficient for the application. The C-grade binning ensures a higher minimum Current Transfer Ratio compared to lower grades, providing better noise immunity. Consider the 80 V collector-emitter voltage rating relative to the load requirements. The 5 mA forward current drive requirement should be compatible with the source logic levels.

Part Context

This part belongs to the DPC816 series of transistor output optocouplers manufactured by Diodes Incorporated. The series includes various grades distinguished by letter suffixes, which denote different Current Transfer Ratio bins. The DPC816S-C-TR specifically denotes the C-grade performance level within the standard 80 V collector-emitter voltage family.

Replacement Considerations

Direct replacements must match the SL-4 package and 80 V collector-emitter voltage rating. Verify that substitute parts offer comparable isolation voltage and similar current transfer ratios. Ensure the replacement maintains the same pinout configuration to avoid PCB redesign.
