Overview
The PS2532-2 is a dual-channel phototransistor optoisolator manufactured by CEL. It features a Darlington output configuration housed in an 8-DIP package. The device provides high isolation voltage of 5000 Vrms and supports a maximum collector-emitter voltage of 300 V. It operates with a forward current up to 80 mA and delivers a minimum current transfer ratio of 1500% at 1 mA input. The component is designed for through-hole mounting and offers robust signal transmission across isolated circuits.
Feature Summary
- Dual-channel architecture for independent signal isolation
- High collector-to-emitter voltage capability for demanding applications
- Darlington output structure for enhanced gain
- Robust 5000 Vrms insulation barrier
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission between microcontrollers and high-voltage loads
Procurement Notes
Verify the specific suffix variant, as the base part number may correspond to obsolete or legacy stock. Confirm package dimensions and pinout compatibility with existing PCB footprints. Check manufacturer documentation for updated availability status, as this component series may have been superseded by newer generations. Ensure environmental ratings meet operational requirements.
Selection Notes
Select this component when high voltage isolation and high gain are required in a dual-channel format. The Darlington output provides significant current amplification, suitable for driving relays or LEDs directly. Consider the 300 V collector-emitter rating for high-side switching applications. Verify that the 8-DIP package fits the mechanical constraints of the design.
Part Context
This part belongs to the NEPOC series from California Eastern Laboratories (CEL), known for high-performance optocouplers. The PS2532-2 specifically addresses applications needing dual isolation channels with high voltage tolerance. It represents a legacy solution in the multi-photocoupler category, often replaced by modern equivalents with improved speed or lower power consumption.
Replacement Considerations
Check for direct replacements such as the PS2532-2-A if available. Compare electrical parameters like CTR and isolation voltage against potential substitutes. Ensure pin compatibility and package integrity match the original design requirements before substitution.
