PS2501L-4-A

Overview

The PS2501L-4-A is a four-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and provides 5000 Vrms isolation voltage. The device operates with a maximum collector-emitter voltage of 80 V and a peak forward current of 80 mA. Current transfer ratio ranges from 80% to 600%. Typical rise and fall times are 3 µs and 5 µs, respectively. It is housed in a 16-pin PDIP Gull Wing package and supports an operating temperature range from -55°C to +100°C.

Feature Summary

• Contains four independent channels for multi-circuit isolation
• Utilizes GaAs LED and NPN silicon phototransistor technology
• Provides high insulation voltage capability

Applications

• Industrial control systems requiring multi-channel signal isolation
• Power supply feedback loops
• Communication interface isolation

Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND) before integration into new products. Confirm that the 16-pin PDIP Gull Wing package aligns with existing PCB footprints. Ensure compliance with RoHS directives as specified in the manufacturer documentation. Review the latest datasheet for any potential changes in manufacturing origin or labeling due to recent product change notices.

Selection Notes

Select this component when four isolated channels are required within a single package. The NPN phototransistor output is suitable for standard digital switching applications. Consider the 80 V collector-emitter voltage rating for low-voltage logic interfacing. The wide operating temperature range makes it suitable for harsh industrial environments where thermal stability is critical.

Part Context

This part belongs to the PS2501L series of optically coupled isolators. It shares architectural similarities with the PS2501-4 but utilizes specific packaging and lead configuration variations. The series is designed for general-purpose isolation tasks, offering a balance between channel density and electrical performance parameters defined by the manufacturer.
