DPC817W-B-TU-V

Overview

The DPC817W-B-TU-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an MDIP-4 package with through-hole mounting and provides 5000 VRMS insulation voltage. Key electrical parameters include a collector-emitter voltage of 35 V, maximum collector current of 30 mA, and forward voltage of 1.25 V at 5 mA forward current. The device exhibits a current transfer ratio ranging from 130% to 260%, with a maximum collector-emitter saturation voltage of 200 mV and a rise time of 18 µs.

Feature Summary

• Provides high-voltage isolation capability for signal transmission between isolated circuits
• Utilizes a phototransistor output configuration for standard logic interfacing
• Designed for robust performance in industrial and consumer electronic applications

Applications

• Industrial control systems requiring galvanic isolation
• Consumer electronics signal coupling
• General-purpose logic circuit isolation

Procurement Notes

Verify the specific suffix TU-V against manufacturer documentation to confirm pinout and packaging details. Ensure compatibility with existing board layouts for MDIP-4 through-hole mounting. Cross-reference RoHS compliance status with the latest datasheet revision. Confirm that the 5000 VRMS isolation rating meets system safety requirements. Validate thermal management needs based on the specified forward current and saturation voltage parameters.

Selection Notes

Select this component when a single-channel transistor output optocoupler with high isolation voltage is required. The 130–260% current transfer ratio ensures reliable switching for digital signals. Consider the 35 V collector-emitter voltage limit for low-voltage logic interfaces. The MDIP-4 package suits standard PCB mounting techniques. Evaluate the 18 µs rise time against signal frequency requirements to ensure adequate response speed for the intended application.
