PS2503-1-K-A

Overview

The PS2503-1-K-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor within a DIP-4 plastic package. Key electrical parameters include a collector-emitter breakdown voltage of 40 V, a maximum forward current of 80 mA, and an isolation voltage of 5000 Vrms. The device operates across a temperature range of -55 °C to 100 °C with a typical current transfer ratio of 200%.

Feature Summary

Integrates a GaAs light emitting diode and an NPN silicon phototransistor for optical signal transmission
Provides high insulation capability with 5000 Vrms isolation voltage between input and output circuits
Features a standard DIP-4 plastic package suitable for through-hole mounting applications

Applications

Industrial control systems requiring galvanic isolation
Signal transmission in measurement and testing equipment
Power supply feedback loops for circuit protection

Procurement Notes

Verify the specific suffix K-A against the official Renesas datasheet to confirm pinout and packaging details. Confirm RoHS compliance status as required by project specifications. Check for any product change notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a single-channel transistor output isolator with DIP-4 packaging is required. Ensure the 40 V collector-emitter voltage rating meets the load requirements. Verify that the 80 mA forward current limit is sufficient for the driving circuit design and that the operating temperature range aligns with the environmental conditions.

Part Context

This part belongs to the PS2503 series of low input current optocouplers. The series includes variants such as PS2503-1 and PS2503L-1, which share similar internal structures but may differ in packaging or specific electrical characteristics. The PS2503-1-K-A represents a specific configuration within this family designed for general-purpose isolation tasks.
