PS2501-4-A

Overview

The PS2501-4-A is a transistor output optocoupler from the Renesas PS2501 series, featuring four independent channels in a single package. It utilizes a GaAs light emitting diode coupled with NPN phototransistors to provide electrical isolation. Key electrical parameters include a maximum collector-emitter voltage of 80 V and a maximum collector current of 50 mA per channel. The device offers an insulation voltage of 5000 Vrms and operates within a temperature range of -55°C to +100°C. Typical switching times are 3 µs for rise time and 5 µs for fall time.

Feature Summary

• Four-channel configuration for multi-signal isolation
• High insulation voltage capability
• NPN phototransistor output structure

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback circuits
• Data communication interface isolation

Procurement Notes

Verify component status as this part may be designated as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors as stock levels vary. Ensure compliance with RoHS directives and check for specific packaging requirements such as tube or tray quantities before ordering. Validate that the PDIP-16 package fits the target PCB layout constraints.

Selection Notes

Select this component when multiple isolated channels are required in a compact footprint. Compare against single-channel variants like PS2501-1-A if only one circuit needs isolation. Consider the CTR range of 80% to 600% for drive circuit design. Ensure the 5000 Vrms isolation rating meets the safety standards of the application environment.

Part Context

This part belongs to the PS2501 family of high-isolation optocouplers manufactured by Renesas Electronics. The family includes single-channel (PS2501-1) and four-channel (PS2501-4) versions, as well as lead-free variants (PS2501L). These devices are designed for general-purpose isolation applications where reliable signal transmission across potential barriers is critical.

Replacement Considerations

Direct substitutes include PS2501-4-LD-A and PS2501L-4-A. Verify pinout compatibility and electrical specifications before substitution.
