H11L3W

Logic Output Optoisolators Overview

The onsemi H11L3W is a single-channel, through-hole logic output optocoupler housed in a 6-pin DIP package. It features a DC input driving an open-collector Schmitt trigger output. Key electrical parameters include a maximum forward current of 5mA, a typical rise and fall time of 0.1μs, and a data rate of 1MHz. The device provides high isolation voltage ratings, with specific datasheets citing up to 7500Vrms or 5300Vrms depending on the variant configuration. Operating temperature ranges from -40°C to +85°C.

Logic Output Optoisolators Feature Summary

• Integrates a Schmitt trigger at the output stage to provide noise immunity and clean signal transitions for digital logic interfaces.
• Utilizes a wide-body DIP-6 package design to enhance creepage distance and withstand higher isolation voltages compared to standard packages.
• Offers fast switching performance with low propagation delays suitable for moderate-speed digital communication protocols.

Logic Output Optoisolators Applications

• Microcontroller interface circuits requiring galvanic isolation between logic levels.
• Industrial control systems needing reliable signal transmission across noisy environments.
• Power supply feedback loops for monitoring and control signals.

Logic Output Optoisolators Procurement Notes

Verify the specific isolation voltage rating (e.g., 5300Vrms vs 7500Vrms) against your system requirements, as values vary by regional certification and datasheet version. Confirm the suffix 'W' denotes the wide-body package style essential for high-voltage clearance. Ensure compatibility with your PCB footprint for 6-DIP through-hole mounting before ordering.

Logic Output Optoisolators Selection Notes

Select this component when a built-in Schmitt trigger is required to eliminate signal chatter in noisy digital environments. It is appropriate for applications demanding high isolation integrity via a wide-body package. Consider alternative H11L variants if lower isolation voltage or different packaging styles are sufficient for the design constraints.

Logic Output Optoisolators Part Context

The H11L3W belongs to the H11L series of logic output optocouplers from onsemi. This family is designed for general-purpose digital isolation tasks. The '3' designation typically indicates the specific pinout or internal circuit configuration within the series, while 'W' specifies the wide-body DIP package format.

Logic Output Optoisolators Replacement Considerations

Compatible substitutes within the same family include H11L1VM and H11L2VM. Verify that replacement parts match the required isolation voltage and package dimensions. Ensure the substitute maintains the open-collector Schmitt trigger output characteristic for functional equivalence.
