Overview
The DPC817D-B-TU is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features a phototransistor output with a collector-emitter voltage of 35V and a maximum forward current of 5mA. The device provides high isolation voltage of 5000 Vrms between input and output. Key electrical parameters include a forward voltage of 1.25V, a saturation voltage of 200mV, and a rise/fall time of 18µs. The current transfer ratio ranges from 130% to 260%, with an operating temperature range of -55°C to +110°C.
Feature Summary
- High input-output isolation voltage for enhanced safety
- Transistor output configuration for signal transmission
- Wide operating temperature range for industrial environments
Applications
- Industrial control systems
- Power supply feedback loops
- Signal isolation in communication interfaces
Procurement Notes
Verify the specific suffix TU indicates tube packaging when ordering. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration. Ensure the DIP-4 package dimensions match the target PCB footprint requirements. Cross-reference the part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when high isolation voltage and moderate speed are required. The transistor output type suits applications needing simple switching or analog signal coupling. Consider the 35V collector-emitter limit for load compatibility. Evaluate the CTR range against circuit gain requirements for reliable operation across temperature variations.
Part Context
This part belongs to the DPC817 series of transistor output optocouplers from Diodes Incorporated. It shares functional similarities with other 817-series devices but offers specific performance characteristics defined by its manufacturing lot. The series is designed for general-purpose isolation tasks in various electronic circuits.
Replacement Considerations
Compatible substitutes include PC817 variants from other manufacturers if pinout and electrical specifications align. Verify that replacement parts meet the same 5000 Vrms isolation rating and DIP-4 package constraints.
