PS2501-2XGR

Overview

The PS2501-2XGR is a dual-channel optocoupler manufactured by Isocom Components 2004 LTD. It features an infrared LED input paired with NPN phototransistor outputs in an 8-pin PDIP package. Key electrical parameters include a maximum forward current of 50 mA, a collector-emitter voltage of 80 V, and a minimum current transfer ratio (CTR) of 80%. The device provides high isolation capability with an RMS isolation voltage of 5300 Vrms. Typical switching times are characterized by a rise time of 6 μs and a fall time of 4 μs.

Feature Summary

• Dual-channel configuration providing independent signal isolation for two circuits within a single component.
• High-voltage insulation barrier rated at 5300 Vrms to protect low-voltage control sides from high-voltage loads.
• NPN phototransistor output stage designed for direct interfacing with digital logic families.

Applications

• Industrial motor control systems requiring isolated gate driving or feedback.
• Solid-state relay interfaces for switching AC/DC loads.
• Microcontroller peripheral isolation in noisy environments.

Procurement Notes

Verify the specific suffix 'GR' against the manufacturer's latest datasheet to confirm tape-and-reel packaging specifications. Ensure the required CTR bin matches your circuit design margins, as values may vary between production lots. Cross-reference pinout diagrams to confirm compatibility with existing PCB footprints before finalizing orders.

Selection Notes

Select this component when dual-channel isolation is required in a compact DIP package. The 80V output voltage rating suits standard logic levels, while the 50mA input current allows flexible drive options. Consider the 6μs rise time for applications not requiring ultra-high-speed switching. Verify thermal dissipation requirements if operating near maximum ratings.

Part Context

This part belongs to the PS2501 series, which offers various channel counts and package styles. Isocom Components manufactures these devices as alternatives to legacy parts, often maintaining pin-compatible designs for common commercial optocouplers. The series is noted for meeting global safety standards such as UL certification.

Replacement Considerations

Direct replacements include PS2501-2-XA and PS2501-2-XG from the same manufacturer family. Other compatible equivalents may exist from different vendors, but verification of pinout, CTR ranges, and isolation voltage is mandatory before substitution.
