PS2801A-4-A

Overview

The PS2801A-4-A is a four-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and utilizes an SSOP-16 surface-mount package. Key electrical parameters include a 2500 Vrms insulation voltage, a maximum collector-emitter voltage of 70 V, and a maximum forward current of 30 mA. The device exhibits a current transfer ratio ranging from 50% to 400%, with a typical rise time of 5 µs. It operates within a temperature range of -55°C to +100°C and has a power dissipation rating of 80 mW.

Feature Summary

• Four independent channels for multi-signal isolation
• High isolation voltage capability for safety compliance
• Surface-mount SSOP-16 packaging for density
• NPN phototransistor output configuration

Applications

• Programmable logic controllers
• Measurement instruments
• Power supply circuits
• Mixed integrated circuits

Procurement Notes

Verify the component status before procurement as the PS2801A-4-A is designated as NRND (Not Recommended for New Designs). Confirm availability through authorized distributors, as stock may be limited or subject to special order constraints. Ensure the specific suffix matches the required pinout and performance specifications for your design.

Selection Notes

Select this component when four isolated channels are required in a compact form factor. The 70 V collector-emitter voltage and 30 mA forward current suit standard digital signal isolation tasks. Consider the 5 µs rise time for moderate-speed applications. Verify that the SSOP-16 footprint aligns with the PCB layout requirements.

Part Context

This part belongs to the PS2801A series of high-isolation photo couplers. It shares architectural similarities with other variants like the PS2801-4-A but differs in specific electrical ratings such as current transfer ratio and voltage limits. The series is designed for industrial and commercial applications requiring reliable galvanic isolation between input and output circuits.

Replacement Considerations

The PS2801-4-A is a related variant within the same family. Verify if the higher current transfer ratio and different voltage ratings of the PS2801-4-A are compatible with the existing circuit design. No direct cross-manufacturer substitutes are confirmed in the provided data.
