Overview
The OPIA1210ATUE is a single-channel optoisolator with a transistor output, manufactured by TT Electronics/Optek Technology. It features a 5000Vrms isolation voltage and utilizes a 4-SMD (鸥翼) surface-mount package. The device supports DC input and provides a maximum output voltage of 350V with an output current per channel of 50mA. Key electrical parameters include a minimum current transfer ratio of 50% and a maximum of 600%, both measured at a forward current of 5mA. Typical rise and fall times are 2µs and 3µs, respectively. The component operates within a temperature range of -30°C to 100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Features fast switching speeds suitable for digital signal transmission
- Offers wide operating temperature range for industrial environments
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in noisy electrical environments
- Microcontroller interface circuits for safety isolation
Procurement Notes
Verify the specific suffix ATUE against official datasheets to confirm package type and tape-and-reel configuration. Ensure compatibility with 4-SMD footprint dimensions during PCB layout. Confirm RoHS compliance status through manufacturer documentation prior to integration.
Selection Notes
Select this component when high isolation voltage and moderate speed are required in a compact surface-mount form factor. Consider the 5000Vrms rating for safety-critical applications. Evaluate thermal management requirements given the 100°C upper operating limit.
Part Context
This part belongs to the OPIA series of optoisolators from TT Electronics/Optek Technology. The series includes variants like OPIA814, OPIA815, and OPIA817, which share similar functional characteristics but may differ in packaging or specific electrical ratings. The OPIA1210ATUE specifically denotes the surface-mount version with defined performance metrics.
Replacement Considerations
Officially documented substitutes include other members of the OPIA family such as OPIA814, OPIA815, and OPIA817. Verify pinout compatibility and exact electrical parameter alignment before substitution.
