This fourth pin decouples the gate-drive loop from the main power path, reducing the effective gate inductance and the turn-off voltage spike that can plague 3-pin TO-247 layouts. The part is built on Infineon's Trench Field Stop technology, which balances a low saturation voltage of 2.35 V at 15 V gate drive and 50 A collector current against a fast switching profile — 32 ns turn-on delay and 296 ns turn-off delay at 25 °C under the test condition of 600 V, 50 A, 10 Ohm gate resistor. ## Switching losses and thermal headroom at 175 °C The switching energy at 600 V, 50 A is 2.3 mJ on and 1.9 mJ off, which together with the 255 ns reverse recovery time of the co-packaged diode sets the practical switching frequency ceiling. At 20 kHz switching, the total switching loss alone approaches 84 W before adding conduction loss — the 652 W maximum power dissipation in the TO-247-4 package provides substantial headroom, but the junction-to-case thermal resistance must be managed with a proper heatsink. ## Active lifecycle and ROHS3 compliance It is ROHS3 compliant. The part ships in a Tube, through-hole TO-247-4 package (PG-TO247-4).","metaTitle":"Infineon IKY50N120CH3XKSA1 IGBT, 1200 V 100 A TO-247-4","metaDescription":"Infineon IKY50N120CH3XKSA1 TrenchStop IGBT, 1200 V, 100 A, Vce(on) 2.35 V, TO-247-4 package.

However, the actual continuous current in a real design is limited by the junction temperature — at 100 A and 2.35 V Vce(on), the conduction loss alone is 235 W, so a substantial heatsink and forced airflow are required to stay within the 175 °C Tj(max) limit."},{"question":"Is IKY50N120CH3XKSA1 a direct replacement for IKY50N120CH3?","answer":"The suffix XKSA1 indicates the specific tube-packaged variant in the TO-247-4 package. The IKY50N120CH3 base part number shares the same die and ratings — 1200 V, 100 A, 2.35 V Vce(on). The XKSA1 suffix is the Infineon ordering code for the tube quantity and packaging format.
