PS2501-2

Overview

The PS2501-2X is a dual-channel optocoupler from the PS2501 series, manufactured by Isocom Components. It features an AC input LED and NPN phototransistor output in an 8-pin DIP package. Key electrical parameters include a maximum forward voltage of 1.4V, isolation voltage of 5300Vrms, and typical rise/fall times of 4μs/3μs. The current transfer ratio ranges from 0.8% to 6%. Operating temperature spans -30°C to 100°C.

Feature Summary

• Dual-channel configuration for simultaneous signal isolation
• AC input capability for direct line interfacing
• High isolation voltage rating for safety compliance

Applications

• Logic-to-logic isolation in noisy environments
• Line receiver circuits
• Programmable current level sensors

Procurement Notes

Verify exact suffix (e.g., -2X) against datasheet requirements. Confirm package type matches design constraints. Check UL certification status if required. Ensure operating temperature range meets system specifications. Validate CTR values for circuit compatibility.

Selection Notes

Select based on channel count and input type requirements. Consider isolation voltage needs for safety standards. Evaluate speed requirements against rise/fall times. Verify package compatibility with PCB layout. Check current transfer ratio for drive capability.

Part Context

Part of the PS2501 series offering dual-channel isolation. Designed as a replacement for discontinued components. Manufactured under ISO standards. Suitable for industrial and commercial applications requiring reliable signal transmission across isolated boundaries.

Replacement Considerations

PS2501-2X serves as a direct replacement for similar dual-channel AC-input optocouplers. Verify pinout compatibility before substitution. Check equivalent isolation ratings and CTR specifications.
