Overview
The PS2533L-1-V-A is a single-channel optocoupler featuring a GaAs infrared LED coupled to an NPN silicon Darlington phototransistor. It provides high isolation voltage of 5000Vrms and supports a maximum collector-emitter voltage of 350V. The device operates with a DC input and delivers a typical rise/fall time of 100µs. It is housed in a 4-SMD (DIP-style) package, suitable for surface mount applications.
Feature Summary
- High isolation voltage capability of 5000Vrms
- High collector-to-emitter voltage rating of 350V
- Darlington output configuration for high current transfer ratio
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission across isolated barriers
Procurement Notes
Verify the specific suffix 'A' against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference the Renesas part number with any legacy CEL documentation to avoid discrepancies in mechanical dimensions or electrical specifications during procurement.
Selection Notes
Select this component when high voltage isolation and moderate speed are required. The Darlington output offers high gain but slower switching speeds compared to standard transistors. Verify that the 100µs rise/fall time meets the system timing requirements. Ensure the 4-SMD footprint matches the PCB design constraints.
Part Context
This part belongs to the PS2533 series, which includes variants like PS2533-1 and PS2533L-1. The series is characterized by its use of a GaAs LED and NPN Darlington phototransistor. The 'L' variant typically denotes specific insulation or packaging characteristics within the family. Renesas Electronics is the primary manufacturer associated with this part number lineage.
Replacement Considerations
Direct substitutes include PS2533-1-V-A and PS2533L-1-V-E4. Verify pin compatibility and electrical parameters before substitution. Check for any changes in isolation voltage or current transfer ratio between these variants.
