H11AA1SD is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists onsemi. Its product description is OPTOISO 5.3KV TRANS W/BASE 6-SMD. Review the specifications below when checking this part for your BOM.
The onsemi H11AA1SD is a single-channel MOSFET output optocoupler housed in a surface-mount SMD-DIP-6 package. It provides electrical isolation with an insulation voltage of 5300 Vrms. The device features a Photo MOSFET output type and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a forward current of 16 mA, a forward voltage of 1.75 V, and a reverse voltage of 5 V. Power dissipation is rated at 300 mW.
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability upon receipt. Ensure storage conditions meet moisture sensitivity level requirements to maintain reliability before soldering. Check for obsolescence notices as availability may be limited.
Select this component when high isolation voltage and low leakage are required for analog signals. Compare against alternatives based on package compatibility and thermal performance. Ensure the forward current limits are respected in the circuit design to prevent damage. Verify that the operating temperature range aligns with the final application environment.
This part belongs to the H11 series of optocouplers from onsemi, designed for general-purpose isolation tasks. The SD suffix typically indicates a specific tape and reel packaging configuration for automated assembly. It serves as a discrete solution for isolating low-power control signals from higher voltage domains.
H11F3SR2M is listed as a potential replacement option.
