PS2501-2

Overview

The CEL PS2501-2 is a dual-channel photovoltaic output optoisolator housed in an 8-DIP package. It features a maximum collector current of 50 mA and a collector-emitter saturation voltage of 300 mV. The device supports a reverse voltage of 6 V with a power dissipation of 120 mW. Operating temperatures range from -55°C to +100°C, providing robust isolation for noisy environments.

Feature Summary

• Dual-channel configuration for simultaneous signal isolation
• Photovoltaic output design for low leakage current
• High isolation voltage rating for noise immunity

Applications

• Data transmission in noisy industrial environments
• Microprocessor system isolation
• Power supply feedback circuits

Procurement Notes

Verify the specific suffix (e.g., -A) against your schematic requirements, as variants may exist. Confirm availability status, as this part number is listed as obsolete by some distributors. Ensure the 8-DIP through-hole package matches your PCB footprint. Check replacement options if long-term supply is required.

Selection Notes

Select this component when dual-channel isolation is necessary within a single package. The photovoltaic output type suits applications requiring minimal input drive current. Verify that the 80V collector-emitter voltage meets circuit switching requirements. Ensure the operating temperature range aligns with environmental conditions.

Part Context

This component belongs to the PS2501 series of optically coupled isolators from CEL. The series typically includes single and quad-channel variants. These devices integrate an infrared LED with NPN silicon photo-transistors or photovoltaic outputs. They are designed for general-purpose isolation tasks.

Replacement Considerations

Check for PS2501L-2 as a potential industry-standard substitute. Verify pinout compatibility before substitution. Confirm electrical parameters match original specifications.
