Overview
The Infineon T1601N35TOFXPSA1 is a single-phase controlled rectifier (SCR) module designed for high-power industrial applications. It features a repetitive peak reverse voltage of 3.6 kV and an average on-state current rating of 1900 A, with a maximum RMS current of 29900 A. The device supports a non-repetitive surge current of 44000 A at 50 Hz. Electrical triggering requires a maximum gate trigger current of 350 mA and a maximum gate trigger voltage of 2.5 V. The component operates within a junction temperature range of -40°C to 125°C and utilizes a TO-200AF baseplate mounting configuration.
Feature Summary
- High-voltage blocking capability suitable for demanding power conversion environments
- Robust surge current handling for transient load protection
- Integrated thermal management via baseplate mounting design
Applications
- Industrial motor drives requiring high current capacity
- HVDC transmission systems
- Large-scale welding equipment
Procurement Notes
This component is officially classified as obsolete and no longer manufactured by Infineon Technologies. Verification of availability should focus exclusively on remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific manufacturing date code and storage conditions prior to acquisition, as long-term storage may impact performance reliability. Replacement planning is strongly recommended due to discontinuation status.
Selection Notes
Engineers replacing this part should evaluate the manufacturer-recommended substitute T1601N36TOFXPSA1 for potential compatibility. Selection criteria must prioritize matching the 3.6 kV voltage rating and 1900 A current handling capabilities. Thermal resistance characteristics and mechanical footprint dimensions of the TO-200AF package should be verified against the new component to ensure proper heat sink integration and physical installation without circuit board modifications.
Part Context
The T1601N35TOFXPSA1 belongs to Infineon's high-power thyristor module portfolio, specifically engineered for heavy-duty phase-controlled rectification. It represents a legacy product line that has been succeeded by newer generations offering improved efficiency and switching characteristics. Its design focuses on maximizing current density and voltage stability in stationary industrial power electronics.
Replacement Considerations
Infineon recommends the T1601N36TOFXPSA1 as the direct replacement. This substitute maintains similar electrical specifications but may feature updated internal cell structures. Engineers should verify pinout compatibility and thermal interface requirements before implementation.
