IXYK120N120B3

Overview

The IXYS IXYK120N120B3 is a GenX3™ silicon insulated gate bipolar transistor (IGBT) designed for high-power switching applications. It features a single N-channel configuration housed in a TO-264 package with three terminals. The device supports a maximum collector-emitter voltage of 1.2 kV and a continuous collector current of 120 A at 25°C. Key electrical parameters include a collector-emitter saturation voltage of 1.8 V, a maximum power dissipation of 830 W, and a gate-emitter voltage range of ±20 V. It operates within a temperature range from -55°C to +175°C junction temperature.

Feature Summary

• Utilizes GenX3™ technology for optimized switching performance and low conduction losses.
• Features a robust TO-264 through-hole package suitable for high-current thermal management.
• Designed for high-voltage industrial applications with a 1.2 kV blocking capability.

Applications

• Industrial motor drives and inverters
• High-frequency welding equipment
• Uninterruptible power supplies (UPS)
• Induction heating systems

Procurement Notes

Verify the exact suffix 'B3' against the manufacturer's latest datasheet to confirm pinout and specific electrical tolerances. Ensure the ordering part number matches the required package style and thermal characteristics. Cross-reference with authorized distributors to validate authenticity and traceability documentation before finalizing procurement orders.

Selection Notes

Select this component when a 1.2 kV rating and 120 A continuous current are required in a TO-264 form factor. Compare the 1.8 V saturation voltage against system efficiency targets. Ensure the driving circuit can handle the specified ±20 V gate-emitter limits and that the PCB layout accommodates the thermal requirements of the 830 W power dissipation rating.

Part Context

This model belongs to the IXYS GenX3™ family of high-performance IGBTs. It shares the core technology with other variants like the IXYX120N120B3 but differs in packaging and specific parameter optimization. The series is engineered for demanding power conversion environments requiring high reliability and efficient thermal handling.

Replacement Considerations

Direct replacements may include the IXYX120N120B3 if the PLUS247 package is acceptable. Verify compatibility with the IXGK120N120B3, noting potential differences in saturation voltage and thermal resistance between the B3 and A3 suffixes.
