Overview
The DPC817W-C-TU-V is a transistor output optocoupler manufactured by Diodes Incorporated. It features a phototransistor output and an MDIP-4 through-hole package. Key electrical parameters include a minimum isolation voltage of 5000 Vrms, a maximum collector-emitter voltage of 35 V, and a maximum collector current of 30 mA. The device operates with a forward current of 5 mA and a forward voltage of 1.25 V. The Current Transfer Ratio (CTR) ranges from 200% to 400%. Switching characteristics include a rise time of 18 µs and a fall time of 18 µs.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits via optical coupling.
- Utilizes a phototransistor output configuration for signal transmission.
- Offers a wide Current Transfer Ratio range for varied gain requirements.
- Designed for robust performance in industrial and consumer electronic applications.
Applications
- Industrial control systems requiring galvanic isolation
- Consumer electronics power supply feedback loops
- Signal isolation in microcontroller interfaces
Procurement Notes
Verify the specific CTR ranking suffix 'C' corresponds to the required 200-400% transfer ratio for your design. Confirm the MDIP-4 through-hole package dimensions match your PCB footprint. Ensure the 5000 Vrms isolation rating meets safety standards for your application's voltage class. Cross-reference the datasheet revision date to confirm parameter validity.
Selection Notes
Select this component when a standard 817-series optocoupler is needed but higher CTR consistency is required. The 'C' suffix indicates a tighter binning range compared to lower ranks. Consider the 18 µs switching speed for frequency limitations. The through-hole package is suitable for prototyping or high-reliability manual assembly environments.
Part Context
This part belongs to the DPC817W family of transistor output optocouplers from Diodes Incorporated. It shares the same physical package and basic electrical limits as other variants like the DPC817W-A or DPC817W-B, differing primarily in the Current Transfer Ratio (CTR) binning. The 'TU' suffix typically denotes tube packaging.
Replacement Considerations
Direct substitutes include other DPC817W variants with compatible CTR ranges, such as DPC817W-B-TU-V if lower CTR is acceptable. Generic replacements must match the MDIP-4 package, 35V Vceo, and 5000 Vrms isolation. Verify pinout compatibility before substitution.
