The IGB03N120S7 is a short circuit rugged 1200 V TRENCHSTOP™ IGBT 7 technology device. It features a collector-emitter voltage of 1200 V and a DC collector current of 9 A at 25°C case temperature. The saturation voltage is 2 V at 150°C junction temperature. Short circuit withstand time is 8 µs. Operating junction temperature ranges from -40°C to 150°C. Power dissipation is 37 W at 25°C case temperature.
Verify the exact ordering suffix matches the required package variant, as Infineon uses specific codes for PG-TO-263-3 packages. Confirm that the application does not require automotive qualification (AEC-Q101), as this component is explicitly restricted to industrial use. Ensure thermal management design accounts for the specified Rth(j-c) values under actual operating conditions.
Select this component for low-power industrial drive applications requiring high short-circuit robustness. The 1200 V rating provides sufficient voltage margin for standard three-phase systems. Consider the 9 A continuous current limit when sizing heatsinks, as power dissipation increases significantly with load current and junction temperature.
This part belongs to the TRENCHSTOP™ IGBT 7 family, which utilizes advanced trench gate technology to reduce switching losses compared to previous generations. The S7 designation indicates a balance between conduction and switching performance, suitable for general-purpose industrial inverter topologies where reliability under fault conditions is critical.
Direct replacements within the same PG-TO-263-3 package and electrical ratings should be sought from the IGBT7 S7 portfolio. Verify pinout compatibility and thermal resistance characteristics before substitution.
