H11L3FM is listed in the Logic Output Optoisolators range at ChipApex. The manufacturer field lists onsemi. Its product description is OPTOISO 4.17KV OPN COLL 6-SMD. Review the specifications below when checking this part for your BOM.
The onsemi H11L3FM is a single-channel logic output optocoupler featuring an open-collector phototransistor. It provides 4170Vrms isolation voltage and supports data rates up to 1MHz. The device operates within a temperature range of -40°C to 85°C, with a typical rise/fall time of 100ns. It utilizes a 6-SMD surface-mount package.
Verify the specific suffix 'FM' confirms the 6-SMD tray packaging configuration against official datasheets. Ensure compatibility with surface-mount assembly processes. Confirm RoHS compliance status for the specific manufacturing lot prior to integration into final assemblies.
Select this component when surface-mount space constraints require a compact footprint compared to DIP variants. The high-speed characteristic makes it suitable for applications requiring faster switching than standard optocouplers. Verify that the open-collector output configuration aligns with the downstream logic requirements.
This part belongs to the H11L series, which integrates Schmitt triggers on the input side to improve noise immunity. The 'F' suffix typically denotes the SMD package variant, while 'M' indicates moisture sensitivity or tape/reel handling characteristics depending on the specific manufacturer coding standards.
Direct pin-compatible replacements include other H11L3 variants such as H11L3VM (DIP) or H11L3SR2M (SMD). Verify package dimensions and isolation voltage ratings match before substitution.
