PS2703-1-M-A

Overview

The PS2703-1-M-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared LED with an NPN phototransistor in a plastic SOP-4 package, providing electrical isolation for signal transmission. Key electrical parameters include a collector-emitter breakdown voltage of 120 V and a maximum forward current of 50 mA. The device offers a typical current transfer ratio of 150% and supports high-speed switching with turn-on and turn-off times in the microsecond range. It operates within a temperature range of -55°C to +100°C and features a high isolation voltage rating of 3750 Vrms.

Feature Summary

• High isolation voltage capability of 3750 Vrms for robust circuit protection
• High collector-to-emitter voltage rating of 120 V for demanding applications
• SOP-4 plastic package design optimized for high-density mounting
• UL approved status ensuring compliance with safety standards

Applications

• Hybrid integrated circuits requiring galvanic isolation
• Telephone and fax machine interface circuits
• Programmable logic controllers (PLCs) for input/output isolation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific suffix matches the required pin configuration and insulation class. Check for UL approval documentation if safety certification is mandatory for the end application. Ensure storage conditions comply with moisture sensitivity levels to prevent package degradation prior to assembly.

Selection Notes

Select this component when a high collector-emitter voltage of 120 V is required compared to lower-voltage alternatives in the same family. Consider the SOP-4 package size constraints against available board space. Evaluate the 150% typical current transfer ratio against drive requirements. Verify that the operating temperature range meets the environmental specifications of the target system.

Part Context

This part belongs to the PS2703 series of high-isolation voltage optocouplers from Renesas. The series includes variants such as PS2703-1, PS2703-2, and PS2703-4, differing primarily in channel count and taping options. The PS2703-1 specifically denotes a single-channel configuration housed in the standard SOP-4 package, distinct from the multi-channel versions.
