PS2561L-1-V-F3-W-A

Overview

The PS2561L-1-V-F3-W-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features a 4-pin DIP gull-wing surface-mount package designed for high isolation applications. The device provides an isolation voltage of 5000Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 80V, a peak forward current of 80mA, and a typical forward voltage of 1.4V. The collector current rating is 50mA with a saturation voltage of 300mV maximum. The current transfer ratio ranges from 80% to 400% at 5mA input. Switching characteristics specify typical rise and fall times of 3µs and 5µs respectively. The component operates within a temperature range of -55°C to +100°C.

Feature Summary

• Provides robust galvanic isolation with a 5000Vrms dielectric strength between input and output channels.
• Utilizes a compact 4-pin SMD gull-wing package suitable for automated surface-mount assembly processes.
• Delivers fast switching performance with microsecond-level rise and fall times for signal integrity.
• Ensures reliable operation across a wide industrial temperature range from -55°C to +100°C.

Applications

• High-efficiency digital power supply control loops
• CrM PFC and LLC converter feedback circuits
• Voice-activated DALI lighting control systems
• Industrial motor drive isolation interfaces

Procurement Notes

Verify the specific suffix 'W-A' against official Renesas documentation to confirm tape-and-reel packaging configuration versus tray packing. Confirm RoHS compliance status and REACH registration details prior to procurement. Check for Not Recommended for New Design (NRND) status which may impact long-term availability. Validate that the supplier provides genuine components with traceable manufacturing lot codes. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the datasheet.

Selection Notes

Select this component when high isolation voltage and compact surface-mount form factor are required. Consider the 80V collector voltage limit for low-voltage logic interfacing applications. Evaluate the 80-400% CTR range for compatibility with varying LED drive currents. Compare switching speeds against system bandwidth requirements to ensure adequate response times. Verify thermal management capabilities within the -55°C to +100°C operating window.

Part Context

This part belongs to the PS2561L series of transistor output optocouplers from Renesas. The series is designed for general-purpose isolation in industrial and consumer electronics. It complements other variants like PS2561L-1-A and PS2561L1-1-V-D-A which offer different packaging or lead configurations. The family supports applications requiring reliable DC signal transmission across isolated boundaries.

Replacement Considerations

PS2561L-1-A offers similar electrical specifications but utilizes a standard DIP package rather than SMD. PS2561L1-1-V-D-A provides comparable performance with potential differences in lead finish or packaging format. RV1S9992A is a newer generation optocoupler with increased creepage distance and higher current capacity. Cross-reference pinouts and thermal characteristics before substitution.
