IRG4BC20UD

Overview

The IRG4BC20UD is a single silicon Insulated Gate Bipolar Transistor (IGBT) from Infineon Technologies, designed for high-frequency power switching applications. It features a collector-emitter voltage rating of 600 V and a continuous collector current capability of 13 A at 25°C, with a reduced rating of 6.5 A at 100°C case temperature. The device utilizes a D2PAK (TO-263) surface-mount package to facilitate efficient thermal management in compact designs. Key electrical parameters include a maximum power dissipation of 49 W and an operating junction temperature range spanning from -55°C to +150°C.

Feature Summary

• High-speed switching performance optimized for frequencies between 8 kHz and 60 kHz
• Low on-state voltage drop to minimize conduction losses and improve efficiency
• Robust short-circuit withstand capability ensuring reliable operation under fault conditions
• Designed for copack integration with complementary diodes for simplified circuit topology

Applications

• Switch-mode power supplies (SMPS)
• Motor drive inverters
• Uninterruptible power supplies (UPS)
• Induction heating systems

Procurement Notes

Verify the specific suffix designation against official documentation, as variations may indicate different packaging or qualification standards. Confirm that the procurement channel provides valid traceability for automotive or industrial grade requirements if applicable. Ensure compatibility with existing thermal management solutions given the TO-263 package constraints.

Selection Notes

Select this component when a 600V rating and approximately 13A continuous current are required in a surface-mount form factor. Evaluate the trade-off between the 13A rating at 25°C and the derated 6.5A at 100°C to ensure adequate heatsinking. Consider the ultrafast switching characteristics for applications demanding high frequency operation up to 60 kHz.

Part Context

This IGBT belongs to Infineon's Gen 4 family, representing an evolution in silicon technology for power switching. It is part of a broader portfolio including similar variants like the IRG4BC15UD and IRG4BC20FD, which differ primarily in package type and current handling capabilities. The series is engineered to balance switching speed with low conduction losses.

Replacement Considerations

Direct substitutes within the same family include the IRG4BC15UD for lower current needs or the IRG4BC20FD for through-hole mounting requirements. Cross-brand replacements require careful verification of pinout compatibility, thermal resistance, and switching energy parameters to ensure equivalent performance.
