Overview
The PS2533-2 is a dual-channel transistor output optocoupler manufactured by CEL. It integrates an aluminum gallium arsenide light-emitting diode with an NPN silicon Darlington phototransistor array. The device provides high isolation voltage and collector-to-emitter voltage capabilities. Key electrical parameters include a maximum forward current of 80 mA, a typical forward voltage of 1.15 V, and a maximum collector-emitter saturation voltage of 1 V. It supports a maximum collector current of 150 mA per channel and operates within a temperature range of -55°C to 100°C.
Feature Summary
- Integrates a GaAs LED with an NPN silicon Darlington phototransistor for high gain
- Provides high collector-to-emitter voltage capability suitable for demanding loads
- Offers high isolation voltage rating between input and output circuits
Applications
- Industrial automation control systems
- Power supply feedback loops
- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix (e.g., -V, -A) against the datasheet to ensure correct packaging and compliance status. Confirm availability as distribution status varies by region. Check RoHS compliance markings on official documentation before integration into regulated products.
Selection Notes
Select this component when high current transfer ratio and robust isolation are required. Ensure the load current does not exceed the 150 mA limit. Verify that the operating temperature range meets the environmental requirements of the target application.
Part Context
This part belongs to the NEPOC series of optocouplers from CEL. It is functionally similar to parts from other manufacturers like Renesas but may differ in pinout or mechanical dimensions. Always consult the specific manufacturer datasheet for definitive mechanical and electrical specifications.
Replacement Considerations
Cross-reference with PS2533L-2 for lead-free variants. Verify pin compatibility with PS2533-2 equivalents from other vendors. Ensure replacement parts maintain the same Darlington output configuration and isolation ratings.
