Overview
The PS2533L-1-K-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared LED with an NPN silicon phototransistor in a 4-pin SMD gull-wing package. Key electrical specifications include a collector-emitter voltage of 350 V, an isolation voltage of 5000 Vrms, and a minimum current transfer ratio of 1500% at 1 mA input current. The device supports a maximum forward current of 80 mA and features rise/fall times of 100 µs.
Feature Summary
- High collector to emitter voltage capability for robust circuit isolation
- High isolation voltage rating ensuring safety between input and output circuits
- High current transfer ratio providing efficient signal transmission
Applications
- Industrial automation control systems
- Power supply feedback loops
- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix 'K-A' against official manufacturer documentation to confirm tape and reel packaging requirements and lead time specifications. Ensure compatibility with surface mount assembly processes and check for RoHS compliance status in the latest datasheet revision.
Selection Notes
Select this component when high voltage isolation and high gain are required in a compact surface-mount form factor. Consider the 350 V collector-emitter rating and 1500% minimum CTR for applications demanding reliable switching performance under varying temperature conditions.
Part Context
This part belongs to the NEPOC series of optoisolators from CEL. It is functionally similar to the Renesas PS2533L-1-V-A but may differ in packaging or manufacturing origin. Cross-reference with official substitution lists to ensure pinout and electrical parameter equivalence before implementation.
Replacement Considerations
Official substitute part numbers include PS2533L-1-V-A and PS2533L-1-F3-A. Verify that replacement parts maintain identical pin configurations and electrical ratings to ensure seamless integration without circuit redesign.
