Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Torex Semiconductor. Distributors such as Mouser indicate limited or non-existent availability in certain regions. Verification of stock status and authenticity is critical due to the end-of-life status. Buyers should confirm lead times and source reliability carefully before procurement.

Selection Notes

Select this part only if legacy compatibility or specific historical design requirements necessitate its use. Given its obsolete status, alternative modern equivalents should be evaluated for new designs. Ensure that the 360 mA output current and 9V-15V input range align precisely with the target application's electrical constraints.

Part Context

The XC9401 series belongs to Torex Semiconductor’s portfolio of discrete semiconductor products under power management ICs. This specific model is categorized as an LED driver IC designed for offline AC/DC conversion. It serves niche markets where compact SOT-26 packaging and integrated protection features are prioritized over high-frequency switching performance.
