Overview
The PS2561DL-1Y-V-F3-W-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared LED and an NPN silicon phototransistor within a DIP-4 gull-wing surface mount package designed for long creepage distance. The device provides high isolation voltage of 5000 Vrms and supports an operating ambient temperature up to 110°C. Key electrical parameters include a typical current transfer ratio of 160%, maximum collector-emitter voltage of 80 V, and fast switching times with rise and fall times of 3 µs and 5 µs respectively.
Feature Summary
- High-speed switching capability with typical rise time of 3 µs and fall time of 5 µs
- Long creepage distance design in gull-wing surface mount package
- High isolation voltage rating of 5000 Vrms
- Extended operating ambient temperature range up to 110°C
Applications
- Efficient digital power supply designs
- CrM PFC and LLC converter circuits
- Voice-activated DALI lighting control systems
Procurement Notes
Verify the specific suffix 'F3' indicates tape and reel packaging configuration when sourcing. Confirm that the 'V' and 'W-A' designators align with the required lead bending type and RoHS compliance status for the target application. Cross-reference the manufacturer part number against official Renesas documentation to ensure authenticity and correct revision level before procurement.
Selection Notes
Select this component for applications requiring surface mount assembly with enhanced isolation creepage distances. The high-speed switching characteristics make it suitable for modern digital power conversion topologies. Ensure the circuit design accommodates the 110°C maximum operating temperature and utilizes the specified NPN phototransistor output configuration for proper signal isolation.
Part Context
This part belongs to the NEPOC series of photocouplers from Renesas Electronics. It is functionally related to the PS2561D-1 and PS2561DL-1 families, differing primarily in the package style and manufacturing suffixes. The DL variant specifically denotes the gull-wing lead form factor optimized for surface mount technology while maintaining high isolation performance standards.
Replacement Considerations
The PS2561DL-1Y-V-A is a direct equivalent within the same family offering identical electrical specifications and package dimensions. Designers may also consider the PS2561D-1Y-V-A if through-hole mounting is acceptable, as it shares the same core optocoupler functionality and performance metrics.
