PS2525-1-A

Overview

The PS2525-1-A is a single-channel optocoupler featuring an AC input response and transistor output. It utilizes a large forward input current capability of ±150 mA, enabling direct connection to AC lines without external rectification. The device provides high isolation voltage of 5,000 Vrms between input and output circuits. It is housed in a standard 4-DIP plastic package with tin-lead terminal plating. Key electrical characteristics include a minimum collector-emitter breakdown voltage of 80 V and a rated current transfer ratio of 20%. The unit operates within a temperature range of -55°C to 100°C.

Feature Summary

• AC input response design allows direct interfacing with alternating current signals
• High isolation voltage rating ensures robust circuit separation
• Large forward input current capacity simplifies drive circuitry requirements

Applications

• Industrial control systems requiring AC signal isolation
• Solid-state relay driver circuits
• Microprocessor interface circuits for AC line monitoring

Procurement Notes

Verify the specific suffix '-A' against the manufacturer's current datasheet to confirm pinout compatibility and material composition. Ensure the required isolation voltage rating meets the safety standards of the target application. Confirm availability status directly with CEL or authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when AC input detection is required without additional rectifying components. The high isolation voltage makes it suitable for noisy industrial environments. Compare the current transfer ratio and input current requirements against the driving source capabilities to ensure proper logic level translation.

Part Context

This part belongs to the PS2525 series of AC input response photocouplers manufactured by CEL. The series is designed for applications requiring direct AC line sensing. Variants such as PS2525-1, PS2525-2, and PS2525L-1 share similar functional principles but may differ in packaging, lead configuration, or specific electrical tolerances defined by their respective suffixes.

Replacement Considerations

Cross-reference with PS2525-1 or PS2525L-1 from compatible manufacturers if exact matches are unavailable. Verify that substitute parts maintain the same AC input response characteristic and isolation voltage rating. Check for pin-to-pin compatibility in the 4-DIP package before implementation.
