DPC816D-X-TU

Overview

The DPC816D-X-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 specifications 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 within a temperature range of -55°C to +110°C, with a power dissipation rating of 200 mW.

Feature Summary

• Provides high-voltage isolation between input and output circuits via optical coupling.
• Features a standard NPN phototransistor output for digital signal transmission.
• Designed for reliable operation across extended industrial temperature ranges.

Applications

• Industrial control systems requiring galvanic isolation
• Signal interfacing between microcontrollers and high-voltage loads
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'X' against official Diodes Incorporated documentation to confirm exact binning or testing criteria, as variations may exist compared to standard 'A' or 'B' grades. Ensure the DIP-4 through-hole package aligns with PCB layout requirements. Confirm RoHS compliance status directly from the manufacturer's latest datasheet before finalizing procurement.

Selection Notes

Select this component when a robust, low-cost optocoupler with moderate speed (18 µs rise/fall times) is required. The 80 V collector-emitter voltage suits applications where higher voltage ratings than standard 50 V devices are needed but extreme high-voltage isolation is not critical. Verify that the 30 mA collector current meets load requirements.

Part Context

This part belongs to the DPC816 series of transistor output optocouplers from Diodes Incorporated. These components are widely used in general-purpose isolation applications. The 'DIP-4' designation indicates a four-pin dual in-line package, facilitating easy integration into legacy and modern through-hole circuit designs.

Replacement Considerations

Check for direct pin-compatible substitutes such as the DPC816D-A-TU or DPC816D-B-TU if the 'X' suffix denotes a specific manufacturing lot or minor parameter variation. Ensure replacement parts maintain the same 5000 Vrms isolation rating and DIP-4 package form factor.
