Overview
The CEL PS2505-1 is a single-channel optoisolator featuring an NPN silicon phototransistor output. 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 in an 8-DIP package. Key electrical parameters include a maximum collector-emitter voltage of 80V, a typical forward voltage of 1.17V, and a current transfer ratio ranging from 80% to 600% at 5mA input current.
Feature Summary
- Supports AC input response for versatile signal coupling applications
- Provides high isolation voltage capability of 5000Vrms
- Features high collector-to-emitter voltage rating of 80V
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission between microcontrollers and power circuits
- Noise immunity enhancement in sensitive electronic interfaces
Procurement Notes
Verify the specific suffix and pin configuration against the official datasheet before procurement. Confirm that the 8-DIP package matches your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for any safety standard certifications if used in regulated equipment. Validate component authenticity through authorized channels.
Selection Notes
Choose this component when single-channel isolation with AC input support is required. Consider the 80V output voltage limit for load compatibility. Evaluate the 5000Vrms isolation barrier for safety compliance needs. Assess the thermal performance within the specified -55°C to 100°C range. Compare current transfer ratios for signal integrity requirements.
Part Context
The PS2505 series includes variants like PS2505-2 and PS2505-4, differing primarily in channel count. This model specifically offers one isolated channel. It belongs to the NEPOC series from CEL. The device uses GaAs LED technology for efficient light emission. It is designed for through-hole mounting on printed circuit boards.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify pinout compatibility before replacing existing components. Ensure replacement parts meet identical isolation voltage ratings. Check for equivalent current transfer characteristics. Confirm package dimensions match the original design constraints.
