DPC816L-Y-TR

Overview

The DPC816L-Y-TR is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an SLM-4 surface-mount package with a phototransistor output. Key electrical parameters include a minimum current transfer ratio of 150% and a maximum of 300%. The device supports a forward current of 5 mA with a forward voltage of 1.25 V. It withstands a collector-emitter voltage of up to 80 V and a collector current of 30 mA. Insulation voltage is rated at 5000 Vrms, with saturation voltage at 200 mV max and switching times of 18 us for both rise and fall.

Feature Summary

• Provides high-voltage isolation between input and output circuits via optical coupling.
• Delivers fast switching performance suitable for digital signal transmission.
• Offers consistent current transfer characteristics for reliable logic interfacing.

Applications

• Industrial control systems requiring galvanic isolation
• Signal isolation in microcontroller interfaces
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'Y' corresponds to the required Current Transfer Ratio bin (150%-300%) for your design. Confirm the SLM-4 package dimensions match your PCB footprint. Ensure the 5000 Vrms insulation rating meets safety standards for your application environment. Check RoHS compliance documentation if restricted substances are a constraint.

Selection Notes

Select this component when a standard NPN phototransistor output is needed with moderate speed. The 150-300% CTR range provides flexibility for various load conditions. Consider the SLM-4 package for space-constrained surface-mount designs. Compare against other CTR bins like 'A' or 'X' if different gain levels are preferred.

Part Context

This part belongs to the DPC816L series of transistor output optocouplers from Diodes Incorporated. The series includes variants with different CTR ranges and packaging options such as DIP-4 tubes. The 'TR' suffix indicates tape and reel packaging for automated assembly. Other family members share similar electrical characteristics but differ in CTR specifications or physical form factors.

Replacement Considerations

Direct substitutes within the same family include DPC816L-A-TR and DPC816L-X-TR-V, noting their distinct CTR ranges. Cross-brand replacements must match the 80V Vceo, 30mA Ico, and SLM-4 package constraints. Verify that any alternative maintains the 5000 Vrms isolation voltage rating.
