FODM452R1

Overview

The FODM452R1 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 forward voltage of 1.6 V and a reverse voltage rating of 5 V. Power dissipation is rated at 100 mW, and the current transfer ratio is specified at 50%.

Feature Summary

• High-speed signal transmission capability for digital isolation applications
• Compact five-lead surface-mount footprint for space-constrained designs
• Robust insulation voltage rating for safe circuit separation

Applications

• Industrial automation control systems
• Data communication interface isolation
• Power supply feedback loops

Procurement Notes

Verify the specific suffix R1 against the manufacturer datasheet to confirm pinout and packaging configuration. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the MFP-5 package dimensions with your PCB layout constraints. Confirm that the operating temperature range aligns with your system's environmental specifications before finalizing procurement.

Selection Notes

Select this component when high-speed digital isolation is required in a compact form factor. The 1 Mb/s data rate suits moderate-speed communication interfaces. Consider the phototransistor output characteristics for driving logic inputs. Evaluate the 3750 Vrms isolation barrier against system safety standards. Compare power dissipation limits with thermal management capabilities in the target enclosure.

Part Context

This part belongs to the FODM452 series of high-speed optocouplers manufactured by onsemi. The series is designed for applications requiring reliable galvanic isolation between circuits. The FODM452R1 variant specifically denotes the reel or tape-and-reel packaging configuration. It shares core electrical characteristics with other members of the family while differing in physical packaging details.

Replacement Considerations

Check for direct substitutes within the FODM452 series such as FODM452R2V. Verify pin compatibility and electrical parameter equivalence before substitution. Consult official replacement guides for cross-reference information.
