DPC817S-Y-TR

Overview

The DPC817S-Y-TR is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an SL-4 surface-mount package designed for SMD/SMT installation. Key electrical parameters include a maximum collector-emitter voltage of 35 V, a maximum collector current of 30 mA, and an isolation voltage of 5000 Vrms. The device operates with a forward current of 5 mA and a forward voltage of 1.25 V. The Current Transfer Ratio (CTR) ranges from a minimum of 150% to a maximum of 300%, ensuring reliable signal transmission across the isolation barrier.

Feature Summary

Provides galvanic isolation between input and output circuits using a phototransistor output configuration.
Utilizes a compact SL-4 surface-mount package suitable for automated assembly processes.
Delivers high current transfer efficiency within the specified operating range.

Applications

Signal isolation in industrial control systems
Interface circuits for microcontrollers and logic devices
Power supply feedback loops

Procurement Notes

Verify the specific suffix Y against the manufacturer's latest datasheet to confirm CTR binning and packaging specifications. Ensure the SL-4 footprint matches the target PCB design. Confirm RoHS compliance status through official documentation before finalizing procurement orders.

Selection Notes

Select this component when a 35V output voltage rating and 5000Vrms isolation are required. The 150%-300% CTR range suits applications needing moderate gain. Compare against DPC816L variants if higher voltage ratings or different pinouts are necessary for the specific circuit topology.

Part Context

This part belongs to the DPC817 series of transistor output optocouplers from Diodes Incorporated. The series is designed for general-purpose isolation tasks. The 'Y' suffix typically denotes specific performance binning or packaging variations within the standard product line.
