PS2501A-1-Q-A

Overview

The PS2501A-1-Q-A is a single-channel transistor output optoisolator manufactured by CEL. It features an NPN phototransistor output and operates with a DC input. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 80V, a collector current of 50mA, and a forward voltage of approximately 1.4V at 30mA. The component is housed in a 4-DIP package suitable for through-hole mounting.

Feature Summary

• Provides galvanic isolation between input and output circuits using LED and phototransistor technology
• Features a single channel configuration with NPN phototransistor output
• Designed for through-hole installation in standard 4-DIP packages

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback loops
• Microcontroller interface circuits

Procurement Notes

Verify the specific suffix 'Q' against official datasheets to confirm it denotes the correct package variant or qualification level. Ensure compatibility with existing PCB footprints for 4-DIP components. Confirm availability status as distribution channels may vary for specific suffixes within the PS2501 series.

Selection Notes

Select this component when a single-channel isolation solution with 5000 Vrms rating is required. Compare CTR specifications if precise gain requirements exist. Ensure the 80V collector-emitter voltage meets the load requirements of the target circuit application.

Part Context

This part belongs to the PS2501 series of micro-photo couplers from CEL. The series typically includes variants with different suffixes indicating package types or performance grades. The PS2501A variant generally refers to the standard transistor output version within this family.

Replacement Considerations

Cross-reference with PS2501-1-A or PS2501A-1-A for functional equivalents. Verify pinout compatibility and isolation voltage ratings before substitution.
