Overview
The FODM453V is a high-speed transistor output optocoupler manufactured by onsemi. It features a single channel with a data rate of 1 Mb/s and an isolation voltage of 3750 Vrms. The device utilizes a 5-Mini-Flat (SOP) surface-mount package. Key electrical parameters include a maximum forward current of 25 mA, a typical current transfer ratio of 50%, and a collector output current of 8 mA. It operates within a temperature range of -40°C to +85°C.
Feature Summary
- High-speed operation supporting 1 Mb/s data rates
- Robust insulation capability rated at 3750 Vrms
- Compact 5-pin Mini-Flat surface-mount packaging
Applications
- Industrial communication interfaces
- Signal isolation in microprocessor systems
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'V' indicates the tape and reel packaging configuration as per official datasheets. Confirm that the 5-Mini-Flat package dimensions align with PCB footprint requirements. Ensure compliance with safety standards for reinforced insulation if used in protective circuits. Check for RoHS compliance documentation before finalizing procurement.
Selection Notes
Select this component when high-speed digital isolation is required between circuits operating at different potentials. The 1 Mb/s speed suits standard UART, SPI, or CAN bus applications. Consider the 3750 Vrms isolation rating for noise immunity in industrial environments. Evaluate the 50% CTR to ensure sufficient drive capability for downstream logic inputs.
Part Context
This part belongs to onsemi's FODM453 series of high-speed optocouplers. The series is designed for applications requiring fast signal transmission with galvanic isolation. The FODM453V specifically denotes the version packaged in a 5-Mini-Flat form factor, distinguishing it from tube-packaged variants.
Replacement Considerations
Direct replacements must match the 5-Mini-Flat package, 1 Mb/s speed, and 3750 Vrms isolation. Verify pinout compatibility and current transfer ratio specifications. Cross-reference with other high-speed transistor output optocouplers from major manufacturers ensuring identical functional parameters.
