DPC816D-A-TU

Overview

The DPC816D-A-TU-V 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 maximum 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 exhibits a typical forward voltage of 1.25 V. The Current Transfer Ratio (CTR) ranges from 80% to 160%. Switching characteristics include rise and fall times of 18 µs each. Power dissipation is rated at 200 mW, with an operating temperature range spanning from -55°C to +110°C.

Feature Summary

• Provides high-voltage isolation between input and output circuits via optical coupling.
• Features a standard NPN phototransistor output for direct interface with digital logic or microcontrollers.
• Designed for robust performance across extended industrial temperature ranges.

Applications

• Signal isolation in general-purpose digital communication interfaces
• Switch-mode power supply feedback loop control
• Microcontroller input/output isolation for noise immunity

Procurement Notes

Verify the specific suffix against official Diodes Incorporated documentation, as variants such as DPC816D-A-TU-V exist with identical electrical specifications but potentially different packaging or handling configurations. Confirm RoHS compliance status directly from the manufacturer's datasheet before integration. Ensure the selected package type matches the intended PCB footprint requirements.

Selection Notes

Select this component when a low-cost, single-channel isolation solution with moderate speed is required. The 80 V collector-emitter voltage rating suits low-voltage switching applications. Compare CTR ranks if tighter gain tolerance is necessary for the specific circuit design. Ensure the DIP-4 package fits the available board space and assembly constraints.

Part Context

This part belongs to the DPC816 series of transistor output optocouplers from Diodes Incorporated. The series offers various CTR ranks and package options to accommodate different isolation and signal transmission needs. These devices are commonly used in industrial and consumer electronics where galvanic isolation is critical for safety and noise reduction.

Replacement Considerations

Publicly confirmed substitutes include DPC816D-B-TU and DPC816D-C-TU. Verify that the replacement variant meets the specific CTR and voltage requirements of the original design.
