Overview
The CEL PS2532L-2-A is a dual-channel transistor output optocoupler featuring Photodarlington outputs. It provides high isolation voltage of 5000 Vrms and supports a maximum collector-emitter saturation voltage of 1 V. The device operates with a forward current up to 80 mA and a forward voltage of 1.4 V. It handles a maximum collector current of 200 mA with a power dissipation of 240 mW. The unit functions within a temperature range of -55°C to +100°C and utilizes an 8-SMD package configuration.
Feature Summary
- Dual-channel architecture for simultaneous signal isolation
- High isolation voltage rating for safety-critical applications
- Photodarlington output structure for enhanced gain
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify component authenticity through authorized channels due to discontinued status. Confirm package integrity and pin alignment against original specifications. Review datasheet revisions for any parameter updates. Ensure storage conditions meet manufacturer guidelines to prevent degradation. Validate compatibility with existing circuit designs before integration.
Selection Notes
Evaluate thermal management requirements given the 240 mW power dissipation limit. Consider the 5000 Vrms isolation capability for noise immunity needs. Assess the Photodarlington output speed characteristics against application timing constraints. Verify that the 8-SMD footprint matches the target PCB layout dimensions accurately.
Part Context
This component belongs to the NEPOC series by California Eastern Labs (CEL). It is part of a family of high-isolation photocouplers designed for robust electrical separation. The specific model variant indicates a dual-channel configuration with surface-mount packaging, distinguishing it from single-channel or through-hole alternatives in the same product line.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require design adjustments. Consult manufacturer archives for potential legacy equivalents.
