H11N33S

Logic Output Optoisolators Overview

The onsemi H11N33S is a single-channel logic output optoisolator featuring an infrared LED and an open-collector phototransistor. It provides high isolation voltage of 7500Vrms and supports a CMTI of 5MHz. The device operates within a temperature range of -40°C to +85°C. Packaged in a compact 6-SMD surface-mount configuration, it ensures reliable signal transmission with fast switching characteristics suitable for digital communication interfaces.

Logic Output Optoisolators Feature Summary

• High common-mode transient immunity for noise-resistant operation
• Open-collector phototransistor output for flexible logic interfacing
• Compact surface-mount package design for space-constrained applications

Logic Output Optoisolators Applications

• Digital communication interface isolation
• Microcontroller input/output isolation
• Signal transmission in noisy industrial environments

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'S' indicates the 6-SMD package variant distinct from DIP versions. Confirm datasheet revisions match current production standards. Ensure compliance with RoHS directives if required by your region. Cross-reference pinout diagrams against PCB layout specifications before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required in a small footprint. Compare CMTI ratings against other optocouplers if operating in high-noise environments. Verify that the open-collector output voltage limits align with the receiving circuit's logic levels. Consider thermal management requirements based on ambient operating conditions.

Logic Output Optoisolators Part Context

This part belongs to the H11N series of logic output optoisolators from onsemi. It shares functional similarities with other members like H11N1M but differs in packaging. The series is designed for general-purpose digital isolation tasks where size and speed are critical factors compared to traditional through-hole alternatives.

Logic Output Optoisolators Replacement Considerations

H11N1M serves as a direct functional equivalent in DIP-6 packaging. H11N33SR2 is the tape-and-reel version of the same SMD component. Verify pin compatibility and package dimensions when substituting between DIP and SMD variants.
