Overview
The T731N44TOHXPSA1 is a silicon SCR module manufactured by Infineon Technologies, designed for high-power industrial applications. It features a rated repetitive off-state voltage (VDRM) of 4.4 kV and a non-repetitive peak on-state current of 17 kA. The device operates within a temperature range of -40°C to +125°C and utilizes a press-fit mounting style in the T-7626K package. Key electrical parameters include a maximum holding current of 350 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 350 mA. The off-state leakage current at VDRM is specified at 150 mA.
Feature Summary
- High-voltage capability with a 4.4 kV rating suitable for demanding power conversion environments
- Robust surge handling with a 17 kA non-repetitive peak on-state current capacity
- Secure mechanical connection via press-fit installation method
Applications
- Industrial motor drives
- High-voltage DC transmission systems
- Power factor correction units
Procurement Notes
Verify the specific suffix 'XPSA1' against official Infineon documentation to confirm exact packaging or tape-and-reel specifications, as standard datasheets may list generic variants. Confirm RoHS compliance status through the manufacturer's official product page or certified distributor declarations before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring high blocking voltages and significant surge current tolerance. Ensure the thermal management system supports the operating temperature range up to 125°C. Verify that the gate drive circuit can supply the required 350 mA trigger current reliably under all operating conditions.
Part Context
This part belongs to Infineon's T731 series of high-power SCR modules. These modules are engineered for robust performance in heavy-duty industrial settings. The T731 series typically offers various voltage ratings to accommodate different system requirements while maintaining consistent mechanical and thermal characteristics across the family.
Replacement Considerations
Consult official cross-reference tools for verified substitutes. Ensure any replacement matches the 4.4 kV voltage rating, 17 kA surge current, and T-7626K package dimensions to maintain compatibility with existing press-fit mounting structures.
