Overview
The DPC217S-B-TR is a photodiode output optocoupler manufactured by Diodes Incorporated. It features an infrared emitting diode coupled to a high-speed photodiode detector, providing electrical isolation between input and output circuits. The device is packaged in a compact SSOP-4 surface-mount format, suitable for space-constrained applications. It operates with a standard forward current for the LED and provides a photovoltaic output signal. The component is designed for reliable signal transmission across isolated domains while maintaining high isolation voltage capabilities typical of modern optoisolators.
Feature Summary
- Provides galvanic isolation between input and output circuits using optical coupling
- Integrates an infrared emitter with a fast-response photodiode detector
- Utilizes a compact SSOP-4 surface-mount package for automated assembly
Applications
- Signal isolation in industrial control systems
- Data communication interface protection
- Power supply feedback loop isolation
Procurement Notes
Verify the specific suffix (e.g., -V) against the datasheet to confirm tape-and-reel packaging quantities and RoHS compliance status. Ensure the SSOP-4 footprint matches the PCB design. Confirm that the photodiode output type meets the downstream circuit requirements rather than assuming transistor compatibility.
Selection Notes
Select this component when a photodiode output is required instead of a transistor or logic gate output. Verify that the input forward current and reverse voltage ratings align with the driving source. Ensure the isolation voltage rating satisfies the safety standards of the target application environment.
Part Context
This part belongs to Diodes Incorporated's line of photodiode output optocouplers. It differs from transistor-output variants like the DPC817S series by offering faster switching speeds and linear response characteristics due to the photodiode structure. The SSOP-4 package distinguishes it from through-hole alternatives.
Replacement Considerations
Check for direct substitutes such as the DPC217S-C-TR-V which shares the same family characteristics. Verify pinout compatibility and isolation voltage ratings before substituting with other manufacturers' photodiode optocouplers.
