DPC816D-Y-TU-V

Overview

The DPC816D-Y-TU-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features a phototransistor output and is housed in a DIP-4 through-hole package. Key electrical specifications include an isolation voltage of 5000 Vrms, a collector-emitter voltage of 80 V, and a maximum collector current of 30 mA. The device operates with a forward current of 5 mA and exhibits a typical forward voltage of 1.25 V. Current transfer ratio ranges from 150% to 300%, with rise and fall times of 18 µs each. It supports a power dissipation of 200 mW and functions within a temperature range of -55°C to +110°C.

Feature Summary

• Provides high-voltage isolation capability for signal transmission between isolated circuits
• Utilizes a phototransistor output configuration for digital switching applications
• Designed for robust performance across extended industrial temperature ranges

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 the specific suffix Y against the manufacturer datasheet to confirm the current transfer ratio binning requirements. Ensure the DIP-4 through-hole package aligns with the target PCB footprint. Confirm RoHS compliance status and lead-free characteristics if required by assembly standards. Cross-reference the VDE certification mark if safety isolation is mandated for the end application.

Selection Notes

Select this component when a moderate current transfer ratio between 150% and 300% is sufficient for the logic interface. The 80 V collector-emitter voltage rating suits low-to-medium voltage switching tasks. Consider the 18 µs switching speed for applications not requiring high-frequency operation. The DIP-4 package offers ease of manual handling and prototyping compared to surface-mount alternatives.

Part Context

This part belongs to the DPC816 series of transistor output optocouplers produced by Diodes Incorporated. The series provides various CTR bins to accommodate different sensitivity requirements in isolation designs. The DPC816D-Y variant specifically targets applications needing higher gain than standard variants while maintaining compatibility with common DIP-4 footprints used in legacy and modern electronics.

Replacement Considerations

Direct substitutes within the same family include DPC816D-A-TU-V and DPC816D-C-TU-V, though their current transfer ratios differ significantly. Verify that any replacement maintains the 5000 Vrms isolation rating and DIP-4 package dimensions to ensure mechanical and electrical compatibility.
