PS2861B-1Y-V-F3-A

Overview

The PS2861B-1Y-V-F3-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 shrink small outline package (SSOP-4). The device provides high isolation voltage of 3750 Vrms and supports an operating ambient temperature up to 110°C. Key electrical parameters include a collector-emitter saturation voltage of 300 mV, forward current of 5 mA, and power dissipation of 180 mW. Switching characteristics feature typical rise and fall times of 4 μs and 5 μs respectively.

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required insulation standards and packaging formats. Confirm that the selected variant meets the necessary safety certifications for the target application region. Check component lifecycle status as some variants may be designated as not recommended for new designs. Ensure sourcing channels provide authentic components with traceable documentation.

Selection Notes

Select this component when high isolation voltage and elevated temperature operation are primary requirements. The SSOP-4 package is ideal for space-constrained PCB layouts. Consider the switching speed limitations for high-frequency applications. Evaluate the current transfer ratio requirements against the driving circuit capabilities. Ensure the input forward voltage drop aligns with the available drive voltage levels.

Part Context

This part belongs to the PS2861B-1 series of transistor output optocouplers. It is designed for applications requiring robust electrical isolation and compact form factors. The series is characterized by its ability to operate at higher ambient temperatures compared to standard optocouplers. It serves as a fundamental building block for isolated signal transmission in various electronic systems.

Replacement Considerations

Direct replacements should match the 3750 Vrms isolation rating and SSOP-4 package. Verify pinout compatibility and electrical parameter equivalence. Cross-reference with other Renesas PS28xx series devices if pin-compatible alternatives are needed. Ensure any substitute meets the same safety certification requirements.
