H11L3S

Logic Output Optoisolators Overview

The onsemi H11L3S is a single-channel logic output optocoupler featuring an open-collector phototransistor and an infrared LED. It provides high isolation voltage of 5300 Vrms, ensuring robust signal transmission between isolated circuits. The device operates within a temperature range of -40°C to +85°C and supports data rates up to 1 MHz. Key electrical parameters include a maximum forward current of 30 mA, typical rise/fall times of 100 ns, and a collector-emitter saturation voltage of 0.4 V at 5 mA. It is housed in a compact 6-SMD package suitable for surface mount applications.

Logic Output Optoisolators Feature Summary

• High isolation voltage capability for safe circuit separation
• Schmitt trigger input for noise immunity and clean switching
• Open-collector output for flexible interfacing with various logic families

Logic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Signal interface between microcontrollers and power stages
• Noise-sensitive digital communication lines

Logic Output Optoisolators Procurement Notes

Verify the specific suffix against official datasheets to confirm isolation ratings and packaging options. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure compatibility with your PCB footprint requirements for the 6-SMD package. Check for any recent lifecycle notices or obsolescence warnings directly from onsemi before finalizing procurement plans.

Logic Output Optoisolators Selection Notes

Select this component when high isolation voltage is critical alongside fast switching speeds. The Schmitt trigger input makes it suitable for noisy environments where signal integrity is paramount. Compare its 5300 Vrms rating against other models in the H11L series if higher isolation is not required. Consider the open-collector output configuration for level shifting needs.

Logic Output Optoisolators Part Context

Part of the H11L series, which includes variants like H11L1, H11L2, and H11L3. These devices share similar pinouts and functional characteristics but may differ in isolation ratings or specific electrical parameters. The H11L3S specifically offers enhanced isolation compared to standard versions.

Logic Output Optoisolators Replacement Considerations

H11L3SR2M and H11L3SVM are related variants within the same family. Verify pinout compatibility and isolation voltage specifications before substitution. Ensure that the replacement part meets all environmental and electrical requirements of the original design.
