Overview
The DPC817D-X-TU-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features a DIP-4 through-hole package with an isolation voltage of 5000 Vrms. The device operates within a temperature range of -55°C to +110°C and has a power dissipation rating of 200 mW. Key electrical parameters include a maximum collector-emitter voltage of 35 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%, with rise and fall times specified at 18 µs.
Feature Summary
- Provides high-voltage isolation capability for signal transmission between isolated circuits.
- Utilizes a phototransistor output configuration for reliable switching applications.
- Designed for robust operation across extended industrial temperature ranges.
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal interfacing between microcontrollers and high-voltage loads
Procurement Notes
Verify the specific CTR bin (100-200%) and VDE certification status directly with the manufacturer or authorized distributors, as these attributes define the exact performance tier and regional compliance for this part number. Confirm packaging details such as tube quantity against current production data.
Selection Notes
Select this component when a standard NPN phototransistor output is required with moderate speed characteristics. Ensure the application voltage does not exceed the 35 V collector-emitter limit and that the isolation requirements are met by the 5000 Vrms rating. Consider thermal management given the 200 mW power dissipation constraint in enclosed environments.
Part Context
This part belongs to the DPC817 series of general-purpose optocouplers from Diodes Incorporated. The 'X' suffix typically denotes a specific Current Transfer Ratio (CTR) bin, distinguishing it from other variants like the B or D series which offer different gain ranges. These devices are widely used in legacy and modern designs requiring cost-effective isolation.
Replacement Considerations
Direct substitutes may include other DPC817 series variants with matching CTR bins, such as DPC817D-B-TU-V or DPC817D-D-TU-V, provided their CTR specifications align with the circuit design requirements. Generic 817-series replacements should be evaluated for pin compatibility and insulation distance.
