PS2801C-4-V-A

Overview

The PS2801C-4-V-A is a four-channel phototransistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared emitting diode and NPN silicon phototransistors within a 16-pin SSOP package. Key electrical parameters include an insulation voltage of 2500 Vrms, a maximum collector-emitter voltage of 80 V, and a forward current of 5 mA. The device features a typical rise time of 5 μs and fall time of 7 μs, with a power dissipation rating of 200 mW.

Feature Summary

• Four independent channels for high-density signal isolation
• Integrated shield effect to block ambient light interference
• High-speed switching capability for efficient data transmission
• Compliance with international safety standards including UL and CSA

Applications

• Industrial automation control systems
• Data communication equipment interfaces
• Power supply feedback circuits
• Microcontroller input/output isolation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'V' indicates the required tape and reel packaging configuration. Ensure compliance with RoHS directives as specified in the official datasheet before integration into final assemblies.

Selection Notes

Select this component when four isolated channels are required in a compact surface-mount footprint. The 2500 Vrms insulation rating suits applications demanding robust galvanic isolation between low-voltage logic and higher-voltage loads. Verify thermal management requirements against the 200 mW power dissipation limit.

Part Context

This part belongs to the PS2801 series of high-isolation voltage photocouplers designed for plastic SSOP packages. The series supports high-density applications by combining multiple channels in a small form factor. The PS2801C-4-V-A specifically denotes the four-channel variant with transistor outputs and specific packaging options.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the 16-pin SSOP package dimensions and maintain equivalent insulation voltage ratings.
