OPIA4N35DTUE

Overview

The OPIA4N35DTUE is a high-reliability, single-channel transistor output optoisolator manufactured by TT Electronics/Optek Technology. It features a 6-DIP package and provides an isolation voltage of 5000 Vrms. The device includes a phototransistor with a base lead for enhanced switching speed control. It is designed for demanding industrial, aerospace, and defense applications, supporting MIL-spec screening standards such as MILPRF-19500 and MIL-STD-750.

Feature Summary

• High reliability construction suitable for aerospace and defense environments
• Integrated base lead on the phototransistor output for improved switching performance
• High isolation voltage rating of 5000 Vrms for robust circuit protection

Applications

• Aerospace and defense electronic systems
• Industrial control circuits requiring high isolation
• Military-grade signal transmission interfaces

Procurement Notes

Verify component authenticity through authorized channels due to its specialized military-grade status. Confirm specific screening levels (Group A, B, C, or D) required for your application against MIL-STD-750 or MIL-PRF-38535 standards. Check lifecycle status as availability may be limited compared to commercial variants. Ensure packaging and traceability documentation meet project compliance requirements.

Selection Notes

Select this component when high isolation voltage and ruggedness are critical. The integrated base allows for faster turn-off times compared to standard transistor outputs. Consider it for designs adhering to strict military or aerospace reliability standards. Evaluate space constraints as it utilizes a 6-DIP package. Compare against commercial equivalents if MIL-spec screening is not mandatory for the final system.

Part Context

This part belongs to the Optek high-reliability product line from TT Electronics, which specializes in components for extreme performance designs. The series supports customizable commercial off-the-shelf and MIL-spec options. These devices undergo rigorous screening processes including bond pull samples and non-destructive physical analysis to ensure quality in harsh operating conditions.

Replacement Considerations

Public sources indicate the OPIA4N35DTUE is obsolete. Verify available substitutes from manufacturers like onsemi that offer similar transistor output optoisolators with base leads. Ensure any replacement matches the 5000 Vrms isolation rating and 6-DIP form factor. Confirm compatibility with existing MIL-spec screening requirements if applicable.
