PS2802-1-K-A

Overview

The PS2802-1-K-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN photodarlington output and provides an insulation voltage of 2500 Vrms. The device operates with a forward current of 5 mA and exhibits a fixed current transfer ratio of 2000%. Electrical characteristics include a maximum collector-emitter saturation voltage of 1 V, a rise time of 200 μs, and a fall time of 200 μs. It supports a maximum collector current of 90 mA and a collector-emitter voltage of 40 V.

Feature Summary

High current transfer ratio capability for efficient signal transmission
NPN photodarlington output structure for high gain
Solid electrical isolation barrier for safety compliance

Applications

Industrial automation control systems
Power supply feedback loops
Microcontroller input interfacing

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance details prior to integration. Ensure storage conditions meet manufacturer specifications to maintain reliability. Validate pinout compatibility with existing PCB layouts before finalizing procurement decisions.

Selection Notes

Select this component when high current transfer ratio is required for low input drive applications. The photodarlington output suits interfaces needing higher sensitivity than standard phototransistors. Verify thermal management requirements against the specified power dissipation limits during continuous operation.

Part Context

This part belongs to the PS2802 series of high-isolation optocouplers designed for robust signal transmission across isolated boundaries. The series emphasizes reliability in noisy environments. The specific model utilizes a compact surface-mount package suitable for automated assembly processes in modern electronic manufacturing.
