Infineon Technologies SIGC18T60NCX1SA6

Overview

SIGC18T60NCX1SA6 from Infineon Technologies is a 600 V, 20 A NPT (Non-Punch-Through) IGBT chip with 100 µm die thickness, positive temperature coefficient for stable parallel operation, and 4.3 × 4.3 mm² active die area. It serves as the core switching element in industrial motor drives requiring high-voltage, medium-current power conversion.

For engineers reviewing the SIGC18T60NCX1SA6 datasheet, SIGC18T60NCX1SA6 pinout, SIGC18T60NCX1SA6 application, or SIGC18T60NCX1SA6 equivalent, key selection criteria include V_CE(sat) at 20 A, gate threshold voltage tolerance, thermal resistance implications of 100 µm thickness, and suitability for epoxy or soft-solder die bonding in module assembly.

Technical Context

This IGBT chip employs Non-Punch-Through (NPT) silicon technology, enabling robust short-circuit withstand capability and inherent positive temperature coefficient of V_CE(sat), which simplifies current sharing in paralleled configurations. Its 100 µm thickness balances thermal conductivity and ruggedness for 125 °C junction operation.

Static characteristics are specified at chip level: V_GE(th) ranges 4.5–6.5 V (IC = 0.5 mA), V_CE(sat) is 1.7–2.5 V at V_GE = 15 V and I_C = 20 A, and C_iss measures 900 pF at V_CE = 25 V, supporting predictable gate drive design for hard-switched inverters.

Key Specifications

Pinout & Package

SIGC18T60NCX1SA6 is a bare die (chip-level) device supplied on foil, not in a leaded or surface-mount package. It features three metallized terminals: emitter pad (2.48 × 2.98 mm²), gate pad (0.7 × 1.08 mm²), and collector backside metallization (Ni/Ag system). Bonding is performed via conductive epoxy or soft solder; wire bonding uses Al wires ≤500 µm.

FAQ

Is SIGC18T60NCX1SA6 a packaged device or a bare die?

SIGC18T60NCX1SA6 is a bare die IGBT chip supplied on foil, not in an encapsulated package. It has no leads or molded body and requires mounting onto a substrate (e.g., DBC or IMS) using conductive epoxy or soft solder, followed by aluminum wire bonding. Its ordering code suffix "X1SA6" denotes this die-on-foil configuration per Infineon's internal part numbering convention.

What is the significance of the 100 µm die thickness in thermal design?

The 100 µm thickness balances thermal resistance and mechanical robustness: thinner dies reduce R_thJC but increase fragility during die attach and wire bonding. At 100 µm, SIGC18T60NCX1SA6 achieves optimal junction-to-case thermal impedance for high-power density modules while maintaining >99.5 % die attach yield under industrial reflow or press-bond processes.

Can SIGC18T60NCX1SA6 be directly substituted for FS20R06XL4 modules?

No. SIGC18T60NCX1SA6 is the bare die used *inside* the FS20R06XL4 discrete module, but it is not electrically or mechanically interchangeable. The module includes integrated gate resistor, Kelvin emitter, and isolation; the die requires full module-level packaging, driver matching, and layout optimization. Substitution would require redesigning the entire power stage.

What does "AQL 0.65 for visual inspection" mean for production use?

AQL 0.65 means that Infineon subjects SIGC18T60NCX1SA6 wafers to sampling inspection where the maximum allowable defect rate in a batch is 0.65 % for visible defects (e.g., scratches, passivation voids, pad misalignment). This meets CECC 40000 standards and ensures consistent die quality for high-yield module assembly in volume production.
