DPC816W-X-TU

Overview

The DPC816W-X-TU is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an NPN phototransistor output and is housed in a 4-MDIP package. The device provides 5000 Vrms isolation voltage between input and output. Key electrical parameters include a collector-emitter voltage of 80 V, a maximum collector current of 30 mA, and a forward voltage of 1.25 V at a forward current of 5 mA. The current transfer ratio ranges from 100% to 200%. The unit has a rise time of 18 µs and a power dissipation rating of 200 mW.

Feature Summary

• Provides high-voltage isolation capability for signal transmission between isolated circuits
• Utilizes an NPN phototransistor output stage for digital switching applications
• Designed with a through-hole MDIP-4 package for standard PCB mounting

Applications

• General-purpose signal isolation in industrial control systems
• Interface circuits for microcontrollers requiring galvanic isolation
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix 'X' against the manufacturer's latest datasheet to confirm exact binning or testing criteria, as suffixes often denote specific performance grades or packaging variations. Confirm RoHS compliance status directly with the supplier documentation. Ensure the MDIP-4 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a single channel with moderate speed (18 µs rise time) and high isolation voltage (5000 Vrms) is required. Compare the 80 V collector-emitter voltage limit against your circuit's peak transient voltages. Consider the 100-200% CTR range for logic level compatibility. Evaluate thermal constraints given the 200 mW power dissipation rating in enclosed environments.

Part Context

This part belongs to the DPC816 series of transistor output optocouplers from Diodes Incorporated. It shares functional similarities with other models in the family but differs in specific electrical ratings and packaging options. The series is designed for general-purpose isolation tasks where cost-effectiveness and reliability are prioritized over high-speed data transmission capabilities found in logic-output variants.

Replacement Considerations

Check for direct substitutes such as the DPC816W-B-TU-V or DPC817W-B-TU if different CTR bins or voltage ratings are acceptable. Verify pinout compatibility and package dimensions before substituting. Ensure the replacement part meets the same isolation voltage and current transfer ratio specifications required by the original design.
