Overview
The PS2561B-1-Q-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates an AlGaAs light emitting diode and an NPN silicon phototransistor within a plastic DIP-4 package. The device provides high-voltage isolation with a rated insulation voltage of 5000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a forward voltage of 1.17 V at a forward current of 10 mA. It operates within a temperature range of -55°C to +110°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using optical coupling technology.
- Features a single channel configuration with an NPN phototransistor output for signal transmission.
- Designed for operation in high-temperature environments up to 110°C.
Applications
- Industrial control systems requiring circuit isolation
- Power supply feedback loops
- Signal transmission across isolated grounds
Procurement Notes
Verify the specific suffix 'Q-A' against official Renesas documentation to confirm automotive qualification status and RoHS compliance details. Confirm the current lifecycle status, as variants within this series may be subject to discontinuation or product change notices. Ensure the ordering information matches the exact package type and lead time requirements specified in the latest datasheet before finalizing procurement.
Selection Notes
Select this component when a single-channel optocoupler with 5000 Vrms isolation is required. The NPN phototransistor output suits applications needing standard switching capabilities. Verify that the 80 V collector-emitter voltage and 50 mA current ratings meet the load requirements. Consider the operating temperature range and package constraints during design integration.
Part Context
This part belongs to the PS2561B series of high-voltage isolation optoisolators. The series typically includes variations such as PS2561B-1-A and PS2561B-1-W-A. These devices are designed for general-purpose isolation tasks, offering reliability through the use of AlGaAs LEDs and silicon phototransistors in compact DIP packages.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Renesas Electronics for authorized replacements or cross-reference options based on specific pinout and electrical parameter compatibility.
