Overview
The PS2561AL2-1-V-F3-L-A is a discontinued transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor within a 4-SMD gull-wing package designed for wide lead bending during surface mount assembly. The device provides high isolation voltage of 5000 Vrms, ensuring reliable signal transmission across isolated circuits while maintaining electrical safety standards.
Feature Summary
- Integrates a GaAs light emitting diode with an NPN silicon phototransistor for efficient optical coupling
- Features a specialized wide lead bending design suitable for robust surface mount technology applications
- Provides high dielectric isolation voltage to ensure safe signal transfer between isolated circuit domains
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops for noise immunity
- Microcontroller input interfacing for signal level translation
Procurement Notes
This component is officially discontinued and no longer carried by major distributors such as DigiKey. Verification of current availability is critical as stock may be limited to surplus or obsolete channels. Buyers must confirm end-of-life status and lead times carefully before committing to procurement plans due to the lack of active manufacturing support.
Selection Notes
Engineers should evaluate direct substitutes from the same family, such as the PS2501A-1-A, which remains in production. Considerations must include verifying pin compatibility, isolation voltage ratings, and packaging dimensions to ensure seamless integration into existing designs without requiring significant layout modifications or redesign efforts.
Part Context
Part of the PS2561 series, this model represents a specific variant optimized for surface mount processes. The series is known for combining compact packaging with high reliability. This particular suffix indicates specific tape-and-reel packaging and lead configuration tailored for automated assembly lines in modern electronics manufacturing environments.
Replacement Considerations
Direct substitute: PS2501A-1-A (Renesas Electronics Corporation). Verify functional equivalence and physical footprint compatibility before implementation.
