DPC816L-Y-TR-V

Overview

The DPC816L-Y-TR-V 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. The device utilizes a phototransistor output with a collector-emitter voltage of 80 V and a maximum collector current of 30 mA. 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 current transfer ratio ranges from 150% to 300%, with rise and fall times of 18 µs.

Feature Summary

• Provides high-voltage isolation via 5000 Vrms insulation rating for safe signal transmission between circuits.
• Features a compact SLM-4 surface-mount package designed for automated assembly and space-constrained layouts.
• Delivers consistent signal coupling through a defined current transfer ratio range for reliable switching performance.

Applications

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

Procurement Notes

Verify the specific suffix Y against the manufacturer datasheet to confirm the current transfer ratio binning, as this parameter varies across the DPC816L family. Ensure the SLM-4 footprint matches the design layout. Confirm RoHS compliance status directly with the supplier documentation prior to integration.

Selection Notes

Select this component when a standard NPN phototransistor output is required with moderate speed characteristics. The 80 V collector-emitter voltage suits low-to-medium voltage side applications. Compare the 150-300% CTR range against circuit bias requirements to ensure adequate drive capability without excessive input current.

Part Context

This part belongs to the DPC816L series of transistor output optocouplers from Diodes Incorporated. The series offers various CTR bins denoted by suffixes such as A, B, X, and Y. These devices share common electrical limits including 5 mA forward current and 18 µs switching times, differing primarily in gain specifications.

Replacement Considerations

Direct substitutes within the same family include DPC816L-A-TR-V, DPC816L-B-TR-V, and DPC816L-X-TR-V. Verify that the alternative suffix meets the specific current transfer ratio requirements of the application before substitution.
