R1446NC12E

Overview

The R1446NC12E is a phase control thyristor from the Distributed Gate Capsule Type Series. It features a blocking voltage of 1.2kV and an average current rating of 2940A. The device has a maximum gate trigger voltage (Vgt) of 3V and a maximum gate trigger current (Igt) of 300mA. The maximum on-state voltage (Vtm) is 1.7V. Packaged in TO-200AC, it supports high di/dt and fast low-recovery turn-off capabilities.

Feature Summary

Utilizes unique distributed gate design for enhanced performance
Provides high di/dt functionality with rapid turn-off characteristics
Incorporates life control features for operational stability

Applications

High-power DC phase control applications
Industrial automation systems requiring high current handling
Power conversion equipment utilizing capsule-type thyristors

Procurement Notes

Verify the specific suffix against official Littelfuse or IXYS documentation to confirm exact electrical tolerances and package variations. Ensure compatibility with high-current thermal management requirements. Confirm availability status as component lifecycles may change following corporate acquisitions.

Selection Notes

Select this component for applications demanding high average current and fast switching speeds. The distributed gate architecture offers superior di/dt handling compared to standard designs. Evaluate thermal resistance requirements given the high current ratings and on-state voltage drop.

Part Context

This part belongs to the Distributed Gate Capsule Type Series, designed for robust industrial power control. It represents IXYS's expertise in high-voltage silicon devices, now under Littelfuse ownership. The series targets applications needing reliable high-power switching with minimal recovery losses.

Replacement Considerations

Consult official substitution guides for equivalent high-current SCR capsules. Verify matching blocking voltage, average current, and package dimensions before integration.
