The IXSN35N120AU1 is a high-current power semiconductor module from IXYS, rated at 120A and built to perform reliably in hard-switching and soft-switching power conversion topologies. IXYS modules in the IXSN series are engineered for low on-state losses, robust short-circuit capability, and thermal performance suitable for continuous industrial duty cycles. Whether you are replacing a failed unit or building inventory buffer stock against long factory lead times, the IXSN35N120AU1 delivers the electrical and mechanical consistency that mission-critical systems demand.

The IXSN35N120AU1 is well suited for AC and DC motor drives, regenerative braking systems, UPS and energy storage inverters, induction heating equipment, and industrial welding power supplies. Its 120A continuous current rating supports mid-to-high power density designs where thermal headroom and switching reliability are non-negotiable. Engineers specifying this module will find it compatible with standard isolation base mounting configurations, simplifying retrofit and repair scenarios on existing drive platforms without requiring PCB or heatsink redesign.

Key Features of the IXSN35N120AU1:

• 120A continuous current rating for mid-to-high power industrial drive and conversion applications
• IXYS high-quality silicon construction delivering low forward voltage drop and reduced conduction losses
• Optimized gate charge and switching characteristics for efficient operation at industrial switching frequencies
• Isolated baseplate construction for direct heatsink mounting, simplifying thermal management in enclosed drive enclosures
• Robust short-circuit withstand capability supporting system-level overcurrent protection coordination
• Compatible with standard IXYS module footprints, enabling direct replacement in existing drive and inverter platforms

New production lead times for the IXSN35N120AU1 currently extend to 27 weeks from IXYS — a serious operational risk for facilities running unplanned maintenance cycles or managing lean spare parts inventories. For procurement teams supporting continuous production environments, a 27-week sourcing gap is simply not acceptable. ATI Accurate Technology maintains stock of hard-to-find and long-lead-time IXYS modules precisely to bridge this gap, providing verified new OEM product ready to ship the same day your order is placed.

ATI Accurate Technology is based in Palmetto, Florida, and specializes in power semiconductors including IGBTs, thyristors, diodes, and rectifier modules from leading manufacturers including IXYS. We ship same-day on orders placed before 5PM EST and offer volume pricing for MRO and OEM procurement programs.
