R1448NC20H

Overview

The R1448NC20H is a phase control thyristor manufactured by IXYS, designed for high-power applications. It features a clamp-on W11 package configuration and supports a repetitive peak reverse voltage of 2 kV. The device handles an average on-state current (ITAV) of 1448 A at a case temperature of 55 °C. Key electrical characteristics include a surge current capability of 15,500 A for a 10 ms half-sine wave and an I²t rating of 1.20 x 10⁶ A²s. The turn-off time (Tq) is specified as 40 µs, ensuring rapid commutation suitable for demanding industrial power systems.

Feature Summary

High current handling capacity with 1448 A average on-state current
Robust surge withstand capability rated at 15,500 A
Fast turn-off time of 40 µs for efficient phase control
Clamp-on mechanical design for simplified thermal management

Applications

Industrial phase control systems
High-power rectification circuits
Motor drive applications requiring robust thyristors

Procurement Notes

Verify the specific thermal interface requirements for the W11 clamp-on package to ensure proper mounting pressure and heat dissipation. Confirm that the gate trigger parameters align with the driving circuit capabilities. Ensure the operating environment does not exceed the maximum junction temperature limits defined in the official datasheet. Validate that the system's fault protection mechanisms can handle the specified 15,500 A surge current without damaging the component.

Selection Notes

Select this component when high average current and fast commutation are critical. The 2 kV voltage rating suits medium-voltage AC applications. Consider the W11 package constraints regarding mechanical clamping force and cooling surface area. Compare the 40 µs turn-off time against system frequency requirements to ensure reliable blocking during the off-cycle. Evaluate the I²t rating against potential short-circuit scenarios.

Part Context

This part belongs to IXYS' phase control thyristor portfolio, which offers devices ranging from 400V to 6500V. The W11 package family provides standardized mechanical dimensions for high-current modules. This specific model targets applications needing substantial current handling with precise timing control, fitting within the broader category of industrial power electronics solutions provided by the manufacturer.
