Overview
The OP525F is a photovoltaic output optoisolator manufactured by TT Electronics/Optek Technology. It features a top-view configuration in a 1210 (3225 Metric) surface-mount package. The device utilizes a gallium arsenide infrared LED emitter paired with a silicon photovoltaic detector to provide electrical isolation. Key electrical characteristics include a maximum collector-emitter breakdown voltage of 30 V and a maximum dark current of 100 nA. The component operates within a temperature range of -40°C to +80°C and complies with RoHS3 standards.
Feature Summary
- Provides galvanic isolation between input and output circuits using an infrared LED and photovoltaic detector.
- Generates output voltage directly from incident light without requiring external bias, simplifying circuit design.
- Designed for surface-mount assembly in a compact 1210 footprint to support automated manufacturing processes.
Applications
- Signal isolation in industrial control systems
- Data transmission interfaces requiring electrical separation
- Medical equipment safety circuits
Procurement Notes
Verify the obsolete status of this component before procurement planning. Confirm availability through authorized distributors or approved substitute sources. Ensure that any replacement parts meet the original electrical specifications and mechanical dimensions to maintain system integrity and compliance with regulatory requirements.
Selection Notes
Select this component for applications requiring low-power isolation where direct voltage generation is beneficial. Consider the 30 V breakdown limit and 100 nA dark current when designing high-impedance circuits. Evaluate the 1210 package size against board space constraints and verify thermal management capabilities within the specified operating temperature range.
Part Context
This part belongs to the Optek Technology line of optoelectronic isolators. It is designed for general-purpose isolation tasks where small form factors are required. The product family emphasizes reliability and compatibility with standard surface-mount reflow processes for efficient integration into modern electronic assemblies.
Replacement Considerations
The OP525F is marked as obsolete. Verify if PT42-21B/TR8 serves as a suitable alternative based on specific application requirements and electrical parameter matching.
