TT215N18KOFHPSA1

SCRs - Modules Overview

The TT215N18KOFHPSA1 is a 50 mm press-pack thyristor module from Infineon's Power Block series, designed for high-power phase control applications. It features a repetitive peak off-state voltage of 1800 V and an on-state current rating of 215 A at a case temperature of 85 °C. The device supports a critical rate of rise of on-state current (di/dt)cr of 100 A/µs and can withstand a non-repetitive surge current of 6300 A for 10 ms. Key thermal characteristics include a junction-to-case thermal resistance of 0.13 K/W and a maximum junction temperature of 125 °C.

SCRs - Modules Feature Summary

• Utilizes a robust 50 mm press-pack mechanical design for secure mounting and efficient heat dissipation in high-current environments.
• Engineered for phase control topologies with optimized gate triggering characteristics suitable for industrial power conversion.
• Provides high surge current capability to withstand transient overloads during startup or fault conditions.

SCRs - Modules Applications

• Industrial motor drives and variable frequency drives
• High-power DC-DC converters and rectifiers
• Electrolysis and electroplating power supplies

SCRs - Modules Procurement Notes

Verify the specific suffix HPSA1 against official Infineon documentation to confirm pinout configuration and terminal plating specifications. Ensure that the ordering information matches the exact electrical ratings required for the target application circuit. Cross-reference the datasheet version to validate thermal parameters and absolute maximum ratings before finalizing procurement.

SCRs - Modules Selection Notes

Select this component based on the 1800 V blocking voltage requirement and the 215 A continuous current need under specified cooling conditions. Evaluate the system's di/dt requirements to ensure they do not exceed the 100 A/µs limit without proper snubber circuits. Consider the thermal management strategy given the 0.13 K/W junction-to-case resistance and the 125 °C maximum junction temperature constraint.

SCRs - Modules Part Context

This part belongs to the TT215N family of 50 mm press-pack thyristors, which are standardized components within Infineon's high-power discrete portfolio. The family shares common mechanical dimensions and mounting interfaces, facilitating design flexibility across different voltage and current ratings within the same product line.

SCRs - Modules Replacement Considerations

Direct replacements must match the 50 mm press-pack form factor and 1800 V / 215 A ratings. Verify compatibility with existing gate drive circuits and thermal interface materials. Consult official substitution guides for equivalent parts from the same manufacturer or qualified competitors.
