T1930N34TOFVTXPSA1

Overview

The T1930N34TOFVTXPSA1 is a high-power Silicon Controlled Rectifier (SCR) manufactured by Infineon Technologies. It belongs to the Electrical Triggered Phase Control Thyristor category, designed for robust industrial applications. The device features a ceramic-sealed disc package with a diameter of 75mm and height of 26mm. Key electrical ratings include a repetitive peak off-state voltage (VRRM) and direct current blocking voltage (VDRM) of 3400V. The average on-state current (ITAVM) is rated at 2180A at 180° electrical sine wave conduction. It supports a non-repetitive surge current (ITSM) of up to 17500A for 10ms pulses. The maximum junction temperature (Tvj) is 125°C, with a thermal resistance from junction to case (RthJC) of 21.5 K/kW.

Feature Summary

• Electrical triggering mechanism enables precise phase control in high-power circuits.
• Ceramic sealed disc construction provides mechanical strength and environmental protection against humidity and damage.
• High surge current capability allows handling of transient overloads during startup or fault conditions.

Applications

• High-power DC motor drives and rectifiers
• Industrial heating and welding equipment
• HVDC transmission and static VAR compensators

Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm the specific suffix VT and XPSA1 matches project requirements, as these denote variant specifications. Request original datasheets and material compliance certificates prior to purchase. Check for limited availability status, as this model may be subject to restricted supply or special order constraints. Validate packaging integrity upon receipt to ensure the ceramic seal remains unbroken.

Selection Notes

Select this component when system design requires a 3400V blocking voltage with 2180A continuous current capacity. Ensure the cooling solution can maintain the junction temperature below 125°C under maximum load conditions. Verify that the gate drive circuitry aligns with the electrical triggering requirements specified in the official documentation. Consider the physical dimensions of the 75mm disc package for mechanical mounting and clamp force application within the 20-45 kN range.

Part Context

This part is part of Infineon's high-power thyristor portfolio, specifically engineered for demanding power electronics applications. It shares the T1930 series family characteristics but is distinguished by its 3400V rating. The T1930N34TOFVTXPSA1 serves as a critical switching element in systems requiring high reliability and ruggedness, such as traction converters and industrial power supplies.

Replacement Considerations

Direct substitutes must match the 3400V VRRM, 2180A ITAVM, and 75mm disc package dimensions. Equivalent parts should offer similar RthJC and ITSM capabilities. Verify pinout compatibility if applicable, though disc thyristors are typically symmetric. Consult Infineon for cross-reference recommendations to ensure functional equivalence without redesigning the thermal or mechanical interface.
