T1081N70TOHPRXPSA1

Overview

The T1081N70TOHPRXPSA1 is a high-power silicon SCR module manufactured by Infineon Technologies, designed for phase control applications. It features a rated repetitive off-state voltage (VDRM) of 7 kV and a non-repetitive peak surge current capability of 35 kA. The device operates within a junction temperature range of -40°C to +125°C and utilizes a press-fit mounting style in the T-12026K 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 component is RoHS compliant and supplied in trays with a factory pack quantity of two units.

Feature Summary

• High power handling capability with 7 kV blocking voltage and 35 kA surge current rating
• Robust ceramic metal-sealed construction for reliable operation in harsh environments
• Designed specifically for phase control thyristor (PCT) circuits
• Press-fit installation method ensures secure mechanical connection

Applications

• High voltage DC transmission systems
• Industrial phase control rectifiers
• High power motor drive applications

Procurement Notes

Verify the exact ordering suffix against official Infineon documentation to ensure correct packaging and variant specifications. Confirm that the T-12026K package dimensions align with the intended press-fit assembly requirements. Check for any specific environmental qualification reports or material declarations required for the target application compliance standards.

Selection Notes

Select this module when system requirements demand high voltage isolation up to 7 kV and significant surge current tolerance. Ensure the thermal management design supports the specified operating temperature range of -40°C to +125°C. Verify that the gate drive circuit can provide the necessary 2.5 V trigger voltage and 350 mA current for reliable turn-on under all load conditions.

Part Context

This component belongs to Infineon's NETZ-THYRISTOR series, which focuses on high-voltage phase control solutions. The T1081N70TOHPRXPSA1 represents an evolution of the earlier T1081N70TOH model, maintaining similar electrical characteristics while potentially differing in packaging or supply chain attributes as indicated by the PRXPSA1 suffix.

Replacement Considerations

The T1081N70TOHXPSA1 is listed as an alternative part number with identical electrical ratings. Verify if the suffix change implies any difference in packaging or manufacturing lot before substitution.
