IKY50N120CH3XKSA1

Overview

The IKY50N120CH3XKSA1 is a single N-channel Insulated Gate Bipolar Transistor (IGBT) from Infineon Technologies, belonging to the IGBT HighSpeed 3 series. It utilizes TRENCHSTOP technology and is housed in a TO-247-4-2 through-hole package. The device features a maximum collector-emitter voltage (VCEO) of 1.2 kV and supports a continuous collector current (Ic) of 100 A at 25°C. Key electrical parameters include a collector-emitter saturation voltage of 2 V, a gate-emitter voltage range of -20 V to +20 V, and a power dissipation capability of 652 W. It operates within a temperature range of -40°C to +175°C.

Feature Summary

• Incorporates TRENCHSTOP technology for optimized switching performance and low conduction losses.
• Features a TO-247-4-2 package with an extra Kelvin emitter connection to reduce parasitic inductance in the gate control loop.
• Designed for high reliability with a maximum operating junction temperature of 175°C.

Applications

• Industrial motor drives
• Uninterruptible power supplies (UPS)
• High-frequency welding inverters

Procurement Notes

Verify the specific suffix XKSA1 against official Infineon documentation to confirm pinout compatibility and RoHS compliance status. Ensure the procurement channel provides valid traceability for industrial-grade components. Cross-reference the datasheet revision date to guarantee alignment with current manufacturing specifications before finalizing orders.

Selection Notes

Select this component when a 1.2 kV rating and 100 A continuous current capacity are required in a four-pin TO-247 package. The Kelvin emitter configuration makes it suitable for applications demanding precise gate drive control and reduced switching noise. Compare saturation voltage and thermal resistance against alternative packages if space constraints differ.

Part Context

This part belongs to the IGBT HighSpeed 3 family, which focuses on balancing switching speed and conduction efficiency. The 'Y' designation typically indicates the specific package variant within the broader IKY product line. It serves as a discrete solution for medium-power hard-switching applications where robustness and thermal performance are critical.

Replacement Considerations

Direct replacements must match the 1.2 kV voltage class, 100 A current rating, and TO-247-4-2 package footprint. Verify that any substitute maintains compatible gate charge characteristics and saturation voltage levels to ensure circuit stability without redesigning the gate driver network.
