DPC817D-Y-TU-V

Overview

The DPC817D-Y-TU-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features a phototransistor output and operates in a DIP-4 through-hole package. Key electrical specifications include an isolation voltage of 5000 Vrms, a maximum collector-emitter voltage of 80 V, and a maximum collector current of 30 mA. The device exhibits a forward voltage of 1.25 V at a forward current of 5 mA. The current transfer ratio ranges from 150% to 300%. Switching characteristics include rise and fall times of 18 µs each. It supports a power dissipation of 200 mW and functions within a temperature range of -55°C to +110°C.

Feature Summary

• Provides high-voltage isolation capability with a rated insulation voltage of 5000 Vrms for safe signal transmission between circuits.
• Delivers fast switching performance with symmetric rise and fall times of 18 microseconds for efficient digital signal coupling.
• Offers wide operating temperature stability ranging from -55°C to +110°C suitable for demanding industrial environments.

Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission in microprocessor-based circuits
• Power supply feedback loops

Procurement Notes

Verify the specific suffix TU-V against official Diodes Incorporated documentation to confirm compliance with VDE standards and tube packaging requirements. Ensure the selected variant matches the required current transfer ratio bin (150%-300%) for your circuit design. Cross-reference the datasheet revision date to guarantee parameter accuracy before finalizing procurement orders.

Selection Notes

Select this component when a phototransistor output with high CTR tolerance is required. The 80 V collector-emitter voltage rating distinguishes it from lower-voltage variants like the DPC817D-A or DPC817D-B. Consider the DIP-4 package constraints and through-hole mounting style during PCB layout. Verify that the 18 µs switching speed meets the system's timing requirements.

Part Context

This part belongs to the DPC817 series of transistor output optocouplers produced by Diodes Incorporated. The series utilizes a standard DIP-4 footprint and offers various current transfer ratio grades. The DPC817D-Y-TU-V specifically denotes the Y-grade binning for higher gain applications compared to other series members.

Replacement Considerations

Direct substitutes include other DPC817D-Y-TU-V units from authorized distributors. Alternative brands offering identical pinouts and specifications should be validated against the original datasheet parameters, particularly the 80 V C-E voltage and 150-300% CTR range.
