Overview
The DPC817D-A-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. 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 offers a current transfer ratio ranging from 80% to 160%, with rise and fall times of 18 µs. It operates within a temperature range of -55°C to +110°C.
Feature Summary
- Provides high-voltage isolation between input and output circuits
- Utilizes a phototransistor output for signal transmission
- Designed for through-hole mounting in standard DIP-4 packages
Applications
- General-purpose signal isolation
- Microcontroller interface circuits
- Power supply feedback loops
Procurement Notes
Verify the specific suffix TU-V against the manufacturer's latest datasheet to confirm pinout compatibility and packaging details. Ensure that the required Current Transfer Ratio bin (A) matches the design specifications. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.
Selection Notes
Select this component when a 35 V collector-emitter voltage rating is sufficient for the application. The 80% to 160% CTR range suits applications requiring moderate gain without tight tolerance constraints. Consider alternative bins if higher isolation or faster switching speeds are necessary for the specific circuit design.
Part Context
This part belongs to the DPC817D series of transistor output optocouplers from Diodes Incorporated. The series includes variants with different CTR bins and packaging options. The DPC817D-A-TU-V specifically denotes the A-bin CTR specification and tube packaging format.
Replacement Considerations
Direct substitutes include other DPC817D variants such as DPC817D-B-TU-V or DPC817D-C-TU-V, provided the CTR requirements align. Verify pin compatibility and isolation ratings when considering generic 817-series replacements.
