PS2505L-4

Overview

The CEL PS2505L-4 is a quad-channel optoisolator featuring NPN silicon phototransistor outputs. It provides 5000Vrms isolation voltage and supports AC or DC input signals. The device operates within a temperature range of -55°C to 100°C. Key electrical parameters include a maximum collector-emitter saturation voltage of 300mV, a typical forward voltage of 1.17V, and a current transfer ratio ranging from 80% to 600% at 5mA input. It utilizes an 8-DIP package for through-hole mounting.

Feature Summary

• Contains four independent channels with GaAs light emitting diodes and NPN silicon phototransistors
• Supports both AC and DC input signal types
• Provides high isolation voltage capability

Applications

• Industrial control systems requiring multi-channel isolation
• Signal transmission between isolated circuits
• Microprocessor interface circuits

Procurement Notes

Verify the specific suffix (e.g., -A) against the datasheet to confirm pinout and performance variations. Confirm availability status as some variants may be obsolete. Ensure the 8-DIP package dimensions match the PCB footprint requirements. Check moisture sensitivity level handling procedures if applicable.

Selection Notes

Select this component when four isolated channels are required in a single package. Consider the 5000Vrms isolation rating for safety-critical applications. Evaluate the 80-600% current transfer ratio range for logic level compatibility. Verify the operating temperature range meets environmental conditions.

Part Context

This part belongs to the PS2505 series of optocouplers manufactured by CEL. The series includes variants with one, two, and four channels. The 'L' suffix typically denotes specific packaging or performance options compared to the standard PS2505 line. These devices are designed for general-purpose isolation tasks.

Replacement Considerations

Direct substitutes may include other quad-channel transistor output optocouplers with similar isolation ratings. Verify pin compatibility and electrical specifications before substitution. Consult manufacturer cross-reference lists for confirmed equivalent parts.
