DPC817L-B-TR

Overview

The DPC817L-B-TR is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an SLM-4 surface mount package and provides 5000 Vrms insulation voltage for signal isolation. The device operates with a forward current of 5 mA and a forward voltage of 1.25 V. Key electrical parameters include a collector-emitter voltage of 35 V, a maximum collector current of 30 mA, and a collector-emitter saturation voltage of 200 mV. The Current Transfer Ratio (CTR) ranges from 130% to 260% at the specified test conditions.

Feature Summary

• Provides high input-output isolation voltage of 5000 Vrms
• Features a compact SLM-4 surface mount package configuration
• Delivers guaranteed current transfer ratio performance for reliable switching

Applications

• General purpose signal isolation in industrial control systems
• Microcontroller interface circuits requiring galvanic separation
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the part number matches the specific suffix requirements for tape and reel packaging. Ensure compliance with RoHS directives and check for any recent product change notifications regarding manufacturing updates or material substitutions before finalizing procurement orders.

Selection Notes

Select this component when a surface mount solution with moderate current transfer ratio is required. The SLM-4 package offers space efficiency compared to traditional DIP formats. Consider the 35 V collector-emitter voltage rating for low-voltage logic interfacing applications. Verify thermal management needs as the power dissipation is limited to 200 mW.

Part Context

This component belongs to the DPC817 series of transistor output optocouplers from Diodes Incorporated. The series is designed for general-purpose isolation tasks. The 'B' suffix typically denotes specific CTR binning characteristics. The '-TR' suffix indicates the device is supplied in a tape and reel format suitable for automated surface mount assembly processes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative single-channel transistor output optocouplers with compatible pinouts and similar isolation ratings if direct substitution is necessary.
