H11L2FM

Logic Output Optoisolators Overview

The onsemi H11L2FM is a surface-mount logic output optoisolator featuring an open-collector phototransistor. It provides 4170Vrms isolation voltage and operates within a -40°C to 85°C temperature range. The device supports a maximum forward current of 30mA with a typical forward voltage of 1.2V. It delivers a data rate of 1MHz, characterized by typical rise and fall times of 100ns. Packaged in a compact 6-SMD Gull Wing configuration, it is designed for efficient signal transmission across isolated circuits.

Logic Output Optoisolators Feature Summary

• Signal level shifting between different voltage domains
• Industrial control system interfaces

Logic Output Optoisolators Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and pinout compatibility. Ensure the selected variant matches the required isolation voltage and operating temperature range for the target application environment. Cross-reference manufacturer part numbers to avoid confusion with through-hole equivalents or alternative series members that may share similar base identifiers but differ in physical form factor.

Logic Output Optoisolators Selection Notes

Select this component when surface-mount assembly is required alongside robust noise rejection capabilities. The integrated Schmitt trigger makes it suitable for noisy environments where clean switching is critical. Consider the 6-SMD footprint constraints and verify that the open-collector output architecture aligns with the downstream circuit requirements before finalizing the design.

Logic Output Optoisolators Part Context

This component belongs to the H11L family of logic output optocouplers from onsemi. Unlike standard optocouplers, this series incorporates internal logic conditioning to ensure reliable digital communication. The FM suffix specifically denotes the surface-mount gull-wing package variant, distinguishing it from through-hole DIP versions like the H11L2TVM while maintaining identical electrical performance characteristics.

Logic Output Optoisolators Replacement Considerations

Direct substitutes include other H11L series variants such as H11L2M or H11L2TVM, provided the package difference is accommodated. Verify that any replacement maintains the same 4170Vrms isolation rating and 1MHz data speed. Ensure the replacement also features the open-collector output and Schmitt trigger input to preserve circuit functionality.
