DPC816D-B-TU

Overview

The DPC816D-B-TU is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an NPN phototransistor output and is housed in a DIP-4 through-hole package. Key electrical parameters include a collector-emitter voltage of 80 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 has a typical current transfer ratio ranging from 80% to 160%. Rise and fall times are specified at 18 µs each, with a power dissipation rating of 200 mW.

Feature Summary

• Provides galvanic isolation between input and output circuits via an internal LED and phototransistor structure.
• Features a standard four-pin dual in-line package suitable for through-hole mounting on printed circuit boards.
• Offers high isolation voltage capability to protect low-voltage control circuits from high-voltage load sides.

Applications

• General-purpose signal isolation in industrial control systems
• Switching power supply feedback loops
• Microcontroller interface circuits requiring electrical separation

Procurement Notes

Verify the specific suffix against manufacturer documentation, as variations such as -V or -TR may indicate different packaging or testing standards. Confirm RoHS compliance status directly with the supplier or official datasheet before integration. Ensure the DIP-4 package footprint matches the target PCB design requirements. Cross-reference the part number with the latest product change notices to confirm manufacturing site consistency.

Selection Notes

Select this component when a standard CTR range of 80-160% meets the circuit design requirements. Consider the 80 V collector-emitter voltage limit for appropriate load switching applications. Evaluate the 18 µs switching speed against the system's timing constraints. Compare against higher-speed logic output alternatives if faster response times are necessary for the specific application.

Part Context

This part belongs to the DPC816 series of transistor output optocouplers produced by Diodes Incorporated. The series typically includes variants with different current transfer ratios and packaging options, such as tube or tape-and-reel configurations. These components are designed for general-purpose isolation tasks where moderate switching speeds and standard gain characteristics are sufficient.

Replacement Considerations

Publicly confirmed substitute part numbers for DPC816D-B-TU were not identified in the provided source material. Verify compatibility with generic 816-series optocouplers only if pinout and electrical specifications match exactly.
