FODM611

Logic Output Optoisolators Overview

The FODM611 is a high-speed, single-channel optocoupler featuring a logic gate output with an open-collector configuration. It supports isolated digital communication at data rates up to 10 Mbit/sec. The device provides a high common-mode transient immunity of 20 kV/µs and operates within a temperature range of -40°C to 85°C. Key electrical parameters include a maximum forward voltage of 1.5 V, typical rise time of 20 ns, and typical fall time of 10 ns. It offers an isolation voltage of 3750 Vrms and utilizes a 5-pin Mini-Flat surface-mount package.

Logic Output Optoisolators Feature Summary

• High common-mode transient immunity of 20 kV/µs for robust noise rejection
• Logic gate output with open-collector Schottky clamping for fast switching
• Supports isolated digital signal transmission without conducting ground loops

Logic Output Optoisolators Applications

• Isolated digital communication in industrial systems
• Signal interfacing between microprocessors and power circuits
• Noise-immune data transfer in harsh electromagnetic environments

Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix (e.g., R2) against the required tape-and-reel packaging specifications. Confirm that the Mini-Flat package variant matches the intended PCB footprint requirements. Ensure compliance with RoHS directives and check lead-free soldering compatibility for assembly processes.

Logic Output Optoisolators Selection Notes

Select this component when high-speed data transmission exceeding standard optocoupler limits is required. The 20 kV/µs CMTI rating makes it suitable for applications with significant voltage spikes. The open-collector output requires appropriate pull-up resistor selection to match the target logic voltage levels.

Logic Output Optoisolators Part Context

This device belongs to the FODM series of high-speed optocouplers from onsemi. It is designed to replace older discrete isolation solutions by integrating high-performance LED and photodetector technology into a compact, co-planar package. The series emphasizes reliability and speed for modern digital isolation needs.

Logic Output Optoisolators Replacement Considerations

Direct substitutes may include other onsemi FODM series devices with similar pinouts and electrical characteristics. Verify functional equivalence regarding data rate, isolation voltage, and package dimensions before implementation.
