Overview
The OPI1264 is a single-channel transistor output optocoupler manufactured by TT Electronics/Optek Technology. It features an NPN phototransistor output and supports through-hole mounting. The device provides high isolation with a rated insulation voltage of 15000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 30 V, a maximum collector current of 44 mA, and a minimum current transfer ratio of 12.5% at a forward current of 10 mA. The component operates within a temperature range of -40°C to +85°C.
Feature Summary
- Provides robust electrical isolation between input and output circuits via optical transmission.
- Features an NPN phototransistor output suitable for digital signal switching applications.
- Designed for through-hole installation to ensure secure mechanical attachment on printed circuit boards.
Applications
- General-purpose signal isolation in industrial control systems
- Switching power supply feedback loops
- Microcontroller interface circuits requiring galvanic separation
Procurement Notes
Verify the specific suffix designation when ordering, as variants such as OPI1264A exist with different current transfer ratio specifications. Confirm that the required isolation voltage and thermal operating range align with the target application environment. Ensure compatibility with standard through-hole assembly processes during procurement planning.
Selection Notes
Select this component when high-voltage isolation is required alongside standard NPN switching capabilities. Compare the minimum current transfer ratio against system requirements to ensure adequate noise immunity. Consider the package type and lead configuration for PCB layout constraints relative to other available optocoupler families.
Part Context
This part belongs to the OPI1264 series produced by Optek, now part of TT Electronics. The series includes related models like the OPI1264A, which shares similar physical characteristics but may differ in electrical performance metrics such as current transfer ratio. These components are widely used in applications demanding reliable galvanic isolation.
Replacement Considerations
The OPI1264A is a documented variant within the same series. Verify if the higher current transfer ratio of the A suffix meets design needs. No other direct cross-model substitutes are confirmed in the provided documentation.
