PS2861B-1Y-V-F3-L-A

Overview

The PS2861B-1Y-V-F3-L-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor within a shielded SSOP-4 package. The device provides high isolation voltage of 3750 Vrms and supports an operating ambient temperature up to 110°C. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a typical current transfer ratio of 150%, and switching times of 4 μs rise and 5 μs fall. It is designed for surface mount applications requiring density and reliability.

Feature Summary

• High isolation voltage capability of 3750 Vrms for robust signal transfer
• Extended operating ambient temperature range up to 110°C
• Shielded SSOP-4 package design to minimize ambient light interference
• Fast switching performance with typical rise and fall times under 5 microseconds

Applications

• Interface circuits in industrial control systems
• Signal transfer in high-density mounting environments
• Power supply feedback loops
• General purpose digital isolation

Procurement Notes

Verify the specific suffix configuration against official datasheets, as variations exist within the PS2861B family. Confirm RoHS compliance status and safety certification approvals relevant to your target market. Check current lifecycle status, as some variants may be marked as not recommended for new designs. Ensure the selected part matches the required insulation distance and creepage specifications for your application's safety standards.

Selection Notes

Select this component when high isolation voltage and extended temperature operation are required in a compact surface-mount form factor. Compare the 3750 Vrms rating against system insulation requirements. Evaluate the 110°C thermal limit against ambient conditions. Consider the 4 μs switching speed for signal integrity needs. Verify that the SSOP-4 footprint fits the PCB layout constraints compared to larger packages offering higher isolation distances.

Part Context

This part belongs to the PS2861B-1 series of transistor output optocouplers from Renesas Electronics. The series is characterized by its use of a Shrink Small Outline Package (SSOP) for high-density mounting. It is engineered for applications requiring reliable galvanic isolation between input and output circuits while maintaining a small physical profile suitable for modern electronic assemblies.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Renesas resources or authorized distributors for qualified alternatives. Cross-referencing with other high-isolation optocouplers requires careful verification of pinout compatibility, isolation voltage ratings, and thermal characteristics.
