Overview
The PS2561BL1-1-Q-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor in a lead-bending surface mount package designed for long creepage distance. The device provides high isolation voltage of 5000 Vrms and supports a collector-emitter breakdown voltage of 80 V. It operates within an ambient temperature range of -55°C to 110°C, featuring a typical current transfer ratio of 200% and low dark current.
Feature Summary
- High isolation voltage capability of 5000 Vrms for robust electrical separation
- Extended operating ambient temperature range up to 110°C
- Surface mount package with lead bending design for increased creepage distance
- High current transfer ratio ensuring efficient signal transmission
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback circuits
- Microprocessor input/output interface isolation
- Signal transmission between isolated ground domains
Procurement Notes
Verify the specific suffix codes against official manufacturer documentation to ensure correct package type and compliance status. Confirm that the component meets all required safety certifications for your target market. Check for any recent lifecycle changes or obsolescence notices from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when high isolation voltage and extended temperature operation are critical. The long creepage distance package makes it suitable for applications requiring enhanced safety margins. Ensure circuit design accounts for the specified current transfer ratio variations and switching times for proper signal integrity.
Part Context
This part belongs to the PS2561B series of photocouplers, which are designed for general-purpose isolation applications. The series offers various package options including DIP and surface mount types. The Q-A suffix typically indicates specific compliance or packaging variations defined by the manufacturer.
Replacement Considerations
Direct substitutes include PS2561BL1-1-E3-A and PS2561BL2-1-E3-A from Renesas/NEC. Verify pinout compatibility and parameter equivalence before substitution.
