PS2502-1

Overview

The PS2502-1 is a dual-channel optocoupler manufactured by Isocom Components 2004 Ltd. It features an infrared LED input paired with Darlington transistor outputs, providing high current transfer ratios suitable for driving loads directly. The device offers electrical isolation of 5000Vrms between input and output circuits. It is housed in an 8-pin DIP package designed for through-hole mounting. Key specifications include a maximum forward voltage of 1.4V, a typical rise time of 100μs, and a minimum current transfer ratio of 200%. Operating temperatures range from -30°C to 100°C.

Feature Summary

• Dual-channel configuration with Darlington output transistors for high gain
• High isolation voltage capability for robust circuit protection
• Through-hole DIP packaging for standard PCB integration

Applications

• Industrial control systems requiring galvanic isolation
• Motor control circuits for servo machines
• Logic-to-logic isolation in noisy environments

Procurement Notes

Verify the specific suffix against official Isocom documentation to confirm pinout and electrical tolerances. Ensure the selected variant matches the required isolation voltage and package type for your design. Cross-reference datasheets for thermal limits and current ratings before finalizing procurement orders.

Selection Notes

Select this component when high current drive capability is needed without external amplification. The Darlington output provides significant gain compared to standard transistor outputs. Verify that the 100μs switching speed meets the application requirements, as it is slower than single-transistor variants.

Part Context

Isocom Components specializes in industry-standard optocoupler replacements. The PS2502 series serves as a functional alternative to discontinued parts from major manufacturers. This family focuses on plastic commercial products while maintaining reliability standards established in their military heritage.

Replacement Considerations

Check for direct equivalents such as the PS2502-2N or PS2502L-4-A depending on channel count and package style. Confirm that replacement parts maintain the same 5000V isolation rating and Darlington output characteristics.
