Overview
The OPI150TX is a high reliability optically coupled isolator manufactured by TT Electronics/Optek Technology. It consists of a gallium aluminum arsenide infrared light emitting diode coupled to a transistor output. The device provides electrical isolation with a rating of 50,000 VDC for one channel. It utilizes an axial package configuration suitable for demanding industrial, aerospace, and defense applications requiring robust signal transmission across isolated circuits.
Feature Summary
- Provides high voltage electrical isolation between input and output circuits
- Utilizes a gallium aluminum arsenide infrared LED source for efficient optical coupling
- Features a transistor output stage for digital signal switching
- Designed for extreme performance in harsh environments
Applications
- Aerospace communication systems
- Defense electronics interfaces
- Industrial control isolation
- High-reliability data handling circuits
Procurement Notes
Verify the specific screening level required for your application, as the OPI150 series supports various MIL-PRF-19500 and MIL-STD-750 test methods including Group A, B, C, and D screening. Confirm whether the standard TX or the enhanced TXV variant is needed based on thermal and mechanical stress requirements. Ensure compatibility with axial mounting constraints in your assembly design.
Selection Notes
Select the OPI150TX when high voltage isolation up to 50 kVDC is mandatory. Consider the TXV variant if additional screening such as X-ray inspection or fine leak testing is specified. Evaluate the axial lead form factor against available board space. This component is intended for applications where standard commercial isolators do not meet reliability standards.
Part Context
The OPI150TX belongs to the OPTEK line of high reliability optoelectronics from TT Electronics. This product family is engineered for custom Off-the-Shelf (COTS) and MIL-spec solutions. The brand specializes in discrete semiconductors and sensors designed for sectors like aerospace and defense, emphasizing quality and longevity under extreme conditions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and isolation voltage ratings before considering any alternative components.
