Overview
The T420N12TOFXPSA1 is a silicon SCR module manufactured by Infineon Technologies, designed for high-power industrial applications. It features a single thyristor configuration housed in a TO-200AA base-mount package. The device supports a repetitive peak off-state voltage of 1200 V and an average on-state current of 420 A. It exhibits a non-repetitive surge current capability of 3800 A at 50 Hz. The module operates within a junction temperature range of -40°C to 125°C and includes a gate trigger voltage maximum of 2 V with a gate trigger current maximum of 150 mA.
Feature Summary
- High blocking stability with guaranteed short-circuit failure function
- Base-mount construction for robust mechanical integration
- Single SCR structure optimized for high current handling
Applications
- Industrial motor drives
- Welding equipment
- Resistive heating control systems
Procurement Notes
Verify the specific ordering suffix against official Infineon documentation to confirm exact electrical characteristics and packaging details. Confirm RoHS compliance status and material content declarations prior to procurement. Ensure compatibility with existing thermal management solutions given the TO-200AA form factor. Cross-reference datasheet revisions to validate parameter consistency.
Selection Notes
Select this component for applications requiring high continuous current capacity and robust surge withstand capability. Evaluate thermal resistance requirements based on the specified operating temperature range. Consider the gate drive specifications when designing control circuits. Verify that the 1200 V voltage rating aligns with system transient overvoltage conditions.
Part Context
This part belongs to the T420N series of SCR modules from Infineon Technologies. It shares the same physical footprint and current rating as variants like T420N16TOF but differs in voltage blocking capability. The series is characterized by high power density and reliability for demanding industrial power conversion tasks.
Replacement Considerations
T420N16TOF offers identical current and package specifications with a higher voltage rating of 1600 V. T420N14TOFXPSA1 provides a 1400 V rating within the same series. Verify pinout and thermal interface compatibility before substitution.
