Overview
The PS2533L-1-F3-K-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates an AlGaAs LED with an NPN silicon phototransistor in a compact surface-mount package. The device provides high isolation voltage of 5000Vrms and supports a maximum collector-emitter voltage of 350V. Key electrical characteristics include a minimum current transfer ratio of 1500% at 1mA forward current, a maximum forward current of 80mA, and a typical rise/fall time of 100µs. It operates within a temperature range of -55°C to +100°C.
Feature Summary
- High isolation voltage capability for robust signal transmission across potential barriers
- High current transfer ratio ensures efficient coupling between input and output stages
- Wide operating temperature range suitable for demanding industrial environments
Applications
- Industrial automation control systems requiring galvanic isolation
- Power supply feedback loops for voltage regulation
- Signal interface circuits between microcontrollers and high-voltage loads
Procurement Notes
Verify the specific suffix K-A against official Renesas documentation to confirm tape-and-reel packaging and marking variations. Ensure compliance with RoHS3 standards as indicated in public datasheets. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.
Selection Notes
Select this component when high isolation voltage and high current gain are required in a small surface-mount footprint. Compare performance metrics such as CTR and switching speed against alternative optocouplers if circuit timing constraints are critical. Ensure the 350V collector-emitter rating exceeds the maximum load voltage in the target application design.
Part Context
This device belongs to the PS2533L series of high-isolation photocouplers from Renesas. It shares architectural similarities with other members like the PS2533L-1-V-A but differs in packaging and specific electrical tolerances. The series is designed for applications needing reliable electrical isolation between low-voltage control circuits and higher-voltage power sections.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official Renesas replacement guides or engineering change notices for verified alternatives.
