Overview
The 3N263TX is a high-reliability optically coupled isolator manufactured by TT Electronics/Optek Technology. It features a single channel with a transistor output configuration housed in a TO-72-4 metal can package. The device provides an isolation voltage of 1000VDC and operates within a temperature range of -55°C to 125°C. Designed for demanding environments, it supports DC input types and offers robust performance characteristics suitable for industrial and aerospace applications requiring stringent reliability standards.
Feature Summary
- High-reliability construction designed for extreme performance designs
- Hermetic TO-72-4 metal can packaging for environmental protection
- Transistor output configuration for signal isolation
- Operational capability across extended temperature ranges
Applications
- Aerospace systems requiring MIL-spec components
- Defense electronics utilizing Group A, B, C, & D screening
- Industrial control systems needing high isolation voltage
- Harsh environment instrumentation
Procurement Notes
Verify specific screening levels (Group A, B, C, or D) and process levels (TX, TXV, B, or S) required for the application. Confirm RoHS compliance status as some variants may contain lead. Ensure the TO-72-4 package matches the PCB footprint. Request test data per MIL-STD-750 or MIL-PRF-38535 if mission-critical reliability is mandated.
Selection Notes
Select this component when high reliability and hermetic sealing are prioritized over cost. The TO-72-4 package requires through-hole mounting. Consider the 1000VDC isolation rating for safety barriers. Verify that the transistor output current transfer ratio meets the circuit requirements. Check availability of screened versions against standard commercial grades.
Part Context
The 3N263TX belongs to the Optek high-reliability optoelectronics line from TT Electronics. This series is engineered for customisable commercial off-the-shelf (COTS) and MIL-spec products. The manufacturer provides engineering expertise for extreme performance designs, supporting discrete semiconductors and sensors used in critical infrastructure.
Replacement Considerations
The 3N263 is a related part number within the same series. Verify if the non-TX suffix variant meets the specific screening and testing requirements. Ensure any substitute maintains the TO-72-4 package and 1000VDC isolation rating.
