H11L1FM

Logic Output Optoisolators Overview

The onsemi H11L1FM is a single-channel logic output optocoupler housed in a 6-pin SMD gull-wing package. It features an open-collector phototransistor output driven by an infrared LED, providing galvanic isolation rated at 4170Vrms. The device incorporates Schmitt trigger circuitry to ensure clean digital signal transmission with high noise immunity. Key electrical specifications include a maximum forward voltage of 1.5V and a maximum input current of 60mA. Typical switching performance is characterized by rise and fall times of 0.1μs. The component operates within a temperature range of -40°C to 85°C and complies with VDE and UL safety standards.

Logic Output Optoisolators Feature Summary

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'FM' against official datasheets to confirm the surface-mount gull-wing package variant. Ensure compliance requirements match project needs, as certifications vary by region. Confirm that the 4170Vrms isolation rating meets system safety standards. Cross-reference pinout diagrams to prevent installation errors in PCB layouts.

Logic Output Optoisolators Selection Notes

Select this component when surface-mount assembly is required for isolated digital signaling. The integrated Schmitt trigger makes it suitable for noisy environments where signal integrity is critical. Compare isolation voltage ratings against other variants if higher voltage protection is necessary. Consider thermal management capabilities within the specified operating temperature range.

Logic Output Optoisolators Part Context

The H11L1FM belongs to the H11L series of logic output optocouplers from onsemi. This family is designed for applications demanding reliable digital isolation with fast response times. The FM suffix specifically denotes the surface-mount package option, distinguishing it from through-hole DIP versions like the H11L1M.

Logic Output Optoisolators Replacement Considerations

Direct substitutes include the H11L1M (DIP package) and H11L2M/FM (dual-channel variants). Verify pin compatibility and isolation ratings before substitution.
