TT140N22KOFHPSA2

SCRs - Modules Overview

The TT140N22KOFHPSA2 is a high-power Silicon Controlled Rectifier (SCR) module manufactured by Infineon Technologies. It features a 2200 V repetitive peak reverse voltage rating and supports an average on-state current of 140 A under sinusoidal conditions at 180 degrees electrical conduction. The device utilizes a 34 mm press-pack housing design, facilitating robust thermal management and mechanical mounting. Key electrical characteristics include a maximum junction temperature of 125 °C, a forward voltage drop of 0.9 V at maximum junction temperature, and a critical rate of rise of on-state current of 150 A/µs. The module provides a non-repetitive surge current capability of 3200 A for 10 ms durations.

SCRs - Modules Procurement Notes

Verify the specific ordering suffix HPSA2 against official Infineon documentation to confirm compliance with RoHS directives and packaging specifications. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability. Cross-reference the part number with the latest datasheet version to validate any updates to mechanical dimensions or electrical ratings prior to finalizing orders.

SCRs - Modules Selection Notes

Select this component when designing systems requiring a 2200 V blocking voltage and 140 A continuous current handling capacity within a compact 34 mm footprint. Evaluate the thermal resistance and junction temperature limits to ensure adequate heatsinking infrastructure is available. Confirm that the gate trigger requirements align with the control circuitry capabilities and that the system can withstand the specified surge current ratings during fault conditions.

SCRs - Modules Part Context

This module belongs to the broader family of high-power thyristor devices offered by Infineon Technologies, specifically tailored for demanding industrial power electronics applications. It shares architectural similarities with other press-pack SCR modules in the lineup, such as the TD140N22KOF, but differs in configuration and specific electrical parameters. The product line emphasizes reliability and performance in environments where traditional screw-mount packages may be insufficient.

SCRs - Modules Replacement Considerations

Direct replacements must match the 2200 V voltage rating, 140 A current capacity, and 34 mm press-pack form factor. Verify compatibility with existing cooling solutions and mechanical mounting constraints. Consult official substitution guides for electrically equivalent parts within the same manufacturer's portfolio or approved cross-brand alternatives that meet identical technical specifications.
