Overview
The PS2701-1-F3-H-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and utilizes a 4-pin SOP package for surface mount installation. The device provides high isolation voltage of 3750 Vrms between input and output circuits. Key electrical parameters include a collector-emitter saturation voltage of 300 mV maximum, a forward current of 50 mA, and a typical rise time of 3 μs. It operates within a temperature range of -55°C to +100°C.
Feature Summary
- High isolation voltage capability of 3750 Vrms
- Compact SOP (Small Outline Package) form factor
- High-speed switching performance with 3 μs typical rise time
Applications
- AC input detection circuits
- Industrial control systems
- Power supply feedback loops
Procurement Notes
Verify the specific suffix H-A against the official Renesas datasheet to confirm pinout and packaging details. Check current lifecycle status as some variants in this series may be restricted or obsolete. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.
Selection Notes
Select this component when high isolation voltage and fast switching are required in a compact surface-mount package. Compare the 50 mA forward current and 80 mA collector current limits against system load requirements. Consider the operating temperature range and power dissipation characteristics relative to the application environment.
Part Context
This part belongs to the PS2701 series of transistor output optocouplers from Renesas Electronics. The series is designed for applications requiring electrical isolation between control and power circuits. The SOP-4 package allows for automated assembly and space-efficient design in modern electronic equipment.
Replacement Considerations
Consult the Renesas Product Change Notice for potential substitute part numbers such as PS2761B-1-V-F3-K-A. Verify functional equivalence and pin compatibility before substitution.
