Overview
The OPIA407CTU is a single-channel optoisolator manufactured by TT Electronics/Optek Technology, featuring a transistor output configuration. It provides an isolation voltage of 2500Vrms and operates within a temperature range of -30°C to 100°C. The device accepts AC or DC input with a typical forward voltage of 1.1V and a maximum DC forward current of 50mA. The output transistor supports a maximum collector-emitter voltage of 80V and can handle up to 50mA per channel. Key electrical characteristics include a saturation voltage of 300mV maximum, a current transfer ratio ranging from 0.3% to 3% at 5mA input, and typical rise/fall times of 3µs and 5µs respectively. It is housed in a compact 4-SSOP surface-mount package.

Procurement Notes
Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm final acceptance testing requirements against original design specifications due to end-of-life status. Ensure storage conditions comply with moisture sensitivity level classifications prior to reflow soldering processes.
Selection Notes
Evaluate thermal management requirements given the operating temperature range limits. Assess input current constraints to ensure compatibility with driving logic levels. Verify output voltage ratings match load requirements. Consider physical footprint compatibility with existing PCB layouts when selecting this specific package type.
Part Context
This component belongs to the OPIA400 series of optoisolators produced by TT Electronics/Optek Technology. The series focuses on providing reliable electrical isolation for low-power signal transmission. These devices are engineered for robust performance in environments requiring protection against high voltage transients and electromagnetic interference.
Replacement Considerations
Direct substitute part numbers are not explicitly confirmed in available public documentation for this specific obsolete model. Engineers should consult manufacturer cross-reference guides or datasheets for equivalent single-channel transistor-output optoisolators with matching isolation voltage and package dimensions.
