Overview
The OPI1290-032 is a logic output optocoupler manufactured by TT Electronics/Optek Technology. It functions as a fiber optic isolator with a side-looking configuration and a specified isolation distance of 32mm. The device features a digital output architecture supporting push-pull or totem pole operation within a single channel. Key electrical parameters include an isolation voltage rating of 15,000 Vrms, a forward current (If) of 20 mA, a forward voltage (Vf) of 2.3 V, and a power dissipation (Pd) of 100 mW. This component is designed for high-reliability applications requiring robust signal isolation.
Feature Summary
- Provides high-voltage digital isolation with a 15 kV rating between input and output circuits.
- Utilizes a side-looking optical geometry optimized for specific fiber optic coupling distances.
- Delivers a logic-compatible digital output suitable for direct interface with downstream circuitry.
Applications
- Fiber optic communication systems requiring galvanic isolation
- High-reliability industrial control interfaces
- Aerospace and defense electronic assemblies
Procurement Notes
Verify the specific datasheet version and screening level required for your application, as this component line supports various MIL-spec process levels including Group A through D testing per MIL-PRF-19500 and MIL-STD-750. Confirm that the 32mm isolation distance and side-looking orientation match your mechanical constraints. Ensure compatibility with the 20 mA forward current specification in your drive circuit design.
Selection Notes
Select this component when a high isolation voltage of 15 kV is mandatory alongside a compact fiber optic form factor. The side-looking design necessitates specific alignment considerations compared to top-emitting alternatives. Verify that the 100 mW power dissipation limit accommodates your thermal environment and duty cycle requirements without exceeding the 2.3 V forward voltage drop at the nominal 20 mA operating current.
Part Context
This part belongs to the Optek/TT Electronics family of high-reliability optoelectronics, often utilized in aerospace and defense sectors. The manufacturer offers customizable COTS and MIL-spec products screened under rigorous standards like MIL-STD-883. The OPI series specifically targets applications demanding extreme performance and verified reliability through comprehensive electrical and environmental testing protocols.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Due to the specific 32mm isolation distance and side-looking geometry, alternative components must be evaluated against these unique mechanical and optical constraints rather than generic electrical equivalents.
