PS2801-1-A

Overview

The PS2801-1-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a Gallium Arsenide (GaAs) infrared emitting diode and an NPN silicon phototransistor within a compact SSOP-4 surface-mount package. The device provides high isolation voltage of 2500 Vrms and supports a maximum collector-emitter voltage of 70 V. Key electrical parameters include a forward current of 30 mA, forward voltage of 1.4 V, and power dissipation of 60 mW. The unit operates within a temperature range of -55°C to +100°C and features a typical rise time of 5 µs and fall time of 7 µs.

Feature Summary

• Integrates GaAs LED and NPN phototransistor for optical signal transmission
• Provides high insulation voltage capability for circuit isolation
• Features shielded plastic SSOP-4 package to block ambient light interference
• Supports wide operating temperature range for industrial environments

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific safety certifications required for the target application. Ensure proper handling procedures are followed during assembly to maintain package integrity and electrical performance standards.

Selection Notes

Select this component when single-channel isolation with moderate speed switching is required in space-constrained designs. Consider the SSOP-4 footprint compatibility with existing PCB layouts. Evaluate thermal management requirements given the 60 mW power dissipation limit. Verify that the 70 V collector-emitter voltage rating meets the load requirements of the isolated side circuitry.

Part Context

This part belongs to the PS2801 series of high-isolation voltage photocouplers designed for high-density applications. The series utilizes small and thin SSOP packages with a 1.27 mm pin pitch. The PS2801-1-A variant specifically offers single-channel configuration, distinguishing it from multi-channel counterparts like the PS2801-4-A while maintaining similar isolation and packaging characteristics.

Replacement Considerations

Cross-reference with PS2801-1-F3-P-A for tape-and-reel packaging options. Check PS2801A-1-F3-P-A for alternative specifications within the same family. Verify pinout compatibility and electrical parameter overlaps before substitution.
