PS2802-1-F3

Overview

The PS2802-1-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features a Darlington output configuration with a high isolation voltage of 2500Vrms. The device utilizes a small and thin 4-pin SSOP package with a 1.27 mm pin pitch. Key electrical parameters include a maximum forward current of 50mA, a typical rise/fall time of 200µs, and a minimum current transfer ratio of 200% at 1mA input. The output can withstand a maximum voltage of 40V, with a power dissipation limit of 120mW.

Feature Summary

• High isolation voltage capability for safe signal transmission between isolated circuits
• Darlington output structure provides high current transfer efficiency
• Compact 4-pin SSOP package design suitable for space-constrained applications

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal transmission in noisy environments

Procurement Notes

Verify the manufacturer designation carefully, as sources list both Renesas Electronics and CEL. Confirm the exact suffix (e.g., -A) matches your bill of materials. Ensure the package type is identified as 4-SSOP. Cross-reference the datasheet from the specific supplier to confirm electrical ratings before procurement.

Selection Notes

Select this component when high isolation voltage and high current transfer ratio are required in a compact form factor. The Darlington output is suitable for driving loads directly without additional amplification. Consider the 200µs switching speed limitations compared to faster logic outputs. Verify thermal constraints given the 120mW power dissipation rating.

Part Context

This part belongs to the PS2802 series of high-isolation voltage photocouplers. It is functionally similar to the PS2802-1-F3 but may include specific manufacturing or packaging variations indicated by the suffix. The series is designed for general-purpose isolation in industrial and consumer electronics.
