FODM453R2V

Overview

The FODM453R2V is a high-speed optocoupler from onsemi featuring a single channel with a phototransistor output. It operates within a temperature range of -40°C to +85°C and utilizes an MFP-5 surface-mount package. Key electrical parameters include a data rate of 1 Mb/s, an isolation voltage of 3750 Vrms, and a maximum collector current of 8 mA. The device supports a forward current of 25 mA with a typical current transfer ratio of 50% at 16 mA input.

Feature Summary

• High-speed operation supporting 1 Mb/s data rates for efficient signal transmission
• Compact five-pin mini flat package design suitable for space-constrained applications
• High common-mode rejection capability ensuring reliable performance in noisy environments

Applications

• Industrial communication systems requiring galvanic isolation
• Microcontroller input/output interfacing
• Signal isolation in power supply feedback loops

Procurement Notes

Verify the specific suffix R2V corresponds to the required tape and reel packaging configuration. Confirm that the MFP-5 footprint matches the target PCB layout dimensions. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the datasheet revision to confirm parameter consistency before integration.

Selection Notes

Select this component when high-speed digital isolation is required in a compact form factor. The phototransistor output suits logic-level interfacing where moderate drive strength is sufficient. Consider the 3750 Vrms isolation rating for safety compliance in low-voltage control circuits. Evaluate the 1 Mb/s speed against system timing constraints to ensure adequate noise immunity.

Part Context

This device belongs to the FODM453 series of high-speed optocouplers manufactured by onsemi. The series is designed for applications demanding fast switching speeds and robust isolation characteristics. The MFP-5 package variant offers a smaller footprint compared to traditional DIP packages, facilitating denser circuit board layouts.

Replacement Considerations

Direct substitutes may include other 1-channel, 1 Mb/s transistor-output optocouplers in similar small packages. Verify pinout compatibility and isolation voltage ratings before substitution. Check if alternative manufacturers offer equivalent CTR and propagation delay specifications.
