PS2801C-1-V-P-A

Overview

The PS2801C-1-V-P-A is a single-channel transistor output optoisolator manufactured by Renesas Electronics Corporation. It integrates a Gallium Arsenide (GaAs) infrared emitting diode and an NPN silicon phototransistor within a plastic SSOP package. The device provides high isolation voltage of 2500 Vrms, ensuring effective electrical separation between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 80V, a forward current of 30mA, and a typical rise/fall time of 5µs/7µs. The component operates within a temperature range of -55°C to +100°C.

Feature Summary

• Integrates GaAs LED and NPN phototransistor for DC input coupling
• Provides high insulation voltage of 2500 Vrms for safety isolation
• Utilizes compact 4-pin SSOP surface-mount packaging

Applications

• Industrial control system signal isolation
• Power supply feedback loop isolation
• Microcontroller interface protection

Procurement Notes

Verify the specific suffix 'V-P-A' against official Renesas documentation to confirm pin assignment and package dimensions, as variations exist within the PS2801C family. Ensure compliance with RoHS3 standards if required by the target application. Cross-reference the datasheet revision history for any recent manufacturing or labeling changes that may affect physical compatibility.

Selection Notes

Select this component when a single-channel isolation solution with high speed and robust voltage ratings is required. The 80V output voltage rating suits low-voltage logic interfacing. Consider the 30mA forward current limit and thermal dissipation requirements in the SSOP package during PCB layout design to ensure reliable operation across the specified temperature range.

Part Context

This part belongs to the PS2801C series of optically coupled isolators from Renesas Electronics. The series is characterized by its use of GaAs LEDs and silicon phototransistors to achieve high-speed performance and high isolation capabilities. The PS2801C-1 variant specifically denotes a single-channel configuration, distinguishing it from multi-channel counterparts like the PS2801C-4.

Replacement Considerations
