PS2811-1-F3-K-A

Overview

The PS2811-1-F3-K-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates an AlGaAs LED and an NPN silicon phototransistor within a compact SSOP-4 package. Key electrical specifications include a collector-emitter voltage of 40 V, a maximum collector current of 40 mA, and an isolation voltage of 2500 Vrms. The device operates with a forward current of 5 mA and exhibits a typical current transfer ratio of 200%. Switching characteristics feature a rise time of 4 µs and a fall time of 5 µs. It supports a power dissipation of 180 mW and functions across a temperature range of -55°C to +100°C.

Feature Summary

Provides high-speed switching performance suitable for signal transmission applications
Offers enhanced insulation reliability through a 2500 Vrms isolation rating
Features a shielded plastic SSOP package designed to block ambient light interference

Applications

Industrial control systems requiring galvanic isolation
Signal transmission between microcontrollers and peripheral devices
Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix 'F3' against official Renesas documentation to confirm tape-and-reel packaging compliance. Ensure the K-A variant matches required safety certifications such as UL or VDE if applicable to your design. Cross-reference the datasheet revision date to validate parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a low-profile SMD solution is required for single-channel isolation. The 40 V collector-emitter voltage and 40 mA current capacity suit general-purpose logic interfacing. Consider the 4 µs rise time for moderate-speed digital signals rather than high-frequency data lines.

Part Context

This part belongs to the PS2811 series of high CTR optocouplers. The series is characterized by its use of AlGaAs LEDs for improved efficiency and stability compared to standard GaAs devices. The SSOP-4 form factor allows for high-density PCB mounting in space-constrained electronic assemblies.
