Overview
The DPC817D-X-TU is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features a phototransistor output and is housed in a DIP-4 through-hole package. Key electrical parameters include an isolation voltage of 5000 Vrms, a maximum collector-emitter voltage of 35 V, and a maximum collector current of 30 mA. The device supports a forward current of 5 mA with a forward voltage of 1.25 V. It exhibits a current transfer ratio ranging from 80% to 160%, with rise and fall times of 18 µs. The component operates within a temperature range of -55°C to +110°C and has a power dissipation rating of 200 mW.
Feature Summary
- Provides high-voltage isolation between input and output circuits via optical coupling.
- Utilizes a phototransistor output for signal transmission.
- Designed for through-hole mounting in standard DIP-4 packages.
Applications
- General-purpose signal isolation
- Switching applications
- Microcontroller interface circuits
Procurement Notes
Verify the specific CTR bin (D) and suffix (-TU-V or -TU) against the manufacturer's latest datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and packaging details directly with authorized distributors. Cross-reference the part number with official Diodes Incorporated documentation to validate pinout and absolute maximum ratings before integration.
Selection Notes
Select this component when a robust, general-purpose optocoupler with high isolation voltage is required for through-hole designs. Consider the CTR range and switching speed specifications relative to the target application's timing constraints. Ensure the DIP-4 package fits the PCB layout and that the thermal dissipation capabilities meet the operational environment's demands.
Part Context
This part belongs to the DPC817 series of transistor output optocouplers from Diodes Incorporated. The series is designed for general-purpose isolation tasks. The 'D' suffix typically denotes a specific Current Transfer Ratio (CTR) bin, while '-TU' indicates tube packaging. This family offers a balance of performance and cost-effectiveness for industrial and consumer electronics.
Replacement Considerations
Direct replacements may include other DPC817 variants with different CTR bins or packaging options, such as DPC817D-B-TU-V. Verify pin compatibility and electrical specifications before substitution. Generic 817-series optocouplers from other manufacturers may serve as alternatives if parameters align.
