Overview
The PS2533-1-V-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared LED with an NPN silicon Darlington phototransistor in a 4-pin SMD gull-wing package. Key electrical parameters include a collector-emitter voltage of 350 V, isolation voltage of 5000 Vrms, and forward current of 80 mA. The device exhibits a typical current transfer ratio of 4000%, with a range of 1500% to 6500%. Saturation voltage is 1 V maximum, and rise/fall times are 100 µs.
Feature Summary
- High collector-to-emitter voltage capability for high-voltage switching applications
- High isolation voltage ensuring robust signal transmission across isolated circuits
- High current transfer ratio providing efficient signal coupling with low input drive requirements
Applications
- Industrial automation control systems
- Power supply feedback loops
- Solid-state relay drivers
Procurement Notes
Verify the specific suffix 'V-A' against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives and check for any recent Product Change Notifications (PCN) regarding manufacturing site or material changes before finalizing procurement orders.
Selection Notes
Select this component when high voltage isolation and high collector voltage are required. The Darlington output provides high gain suitable for driving loads directly. Compare rise and fall times against system speed requirements, as the 100 µs delay may limit high-frequency applications. Verify thermal dissipation capabilities within the operating temperature range.
Part Context
This part belongs to the PS2533 series of optically coupled isolators. It is designed for general-purpose isolation where high voltage withstand and high current transfer efficiency are critical. The series typically includes variants with different packaging options such as DIP and SMD configurations.
Replacement Considerations
Check for direct substitutes like PS2533L-1-V-A if lead length variations are needed. Verify pinout compatibility and electrical parameter equivalence with other high-voltage Darlington optocouplers from Renesas or alternative manufacturers.
