Infineon Technologies SIGC18T60SNCX1SA3

Overview

SIGC18T60SNC from Infineon Technologies is a 600 V, 20 A NPT (Non-Punch-Through) IGBT die in bare-die format, designed for high-voltage switching in motor drives and industrial inverters. It features 100 µm chip thickness, positive temperature coefficient for stable paralleling, short-circuit ruggedness, and 4.3 × 4.3 mm² active die area. Used in SGP20N60 TO-220 packaged modules.

For engineers reviewing the SIGC18T60SNC datasheet, SIGC18T60SNC pinout (emitter/gate/collector terminals), SIGC18T60SNC application in motor drives, or SIGC18T60SNC equivalent bare-die IGBTs, this page delivers verified die-level specifications, thermal and switching behavior, and direct integration guidance for discrete power module assembly.

Technical Context

This NPT IGBT die employs planar gate structure with Al–Si 1% emitter metallization and Ni–Ag collector metallization, optimized for 400 V DC-link operation at 150 °C junction temperature. Its 1.6–2.5 V V_CE(sat) at 20 A and 15 V V_GE enables low conduction loss, while 250–300 ns turn-off delay supports high-frequency PWM up to 20 kHz in hard-switched topologies.

Dynamic performance is characterized by C_iss = 1100–1320 pF, C_oss = 107–128 pF, and Crss = 63–75 pF at V_CE = 25 V, enabling predictable gate drive design with 16 Ω external resistor. The die's photoimide passivation and 0.65 mm ink dot support automated die attach and optical alignment in module manufacturing.

Key Specifications

Pinout & Package

FAQ

What is the recommended gate resistor value for SIGC18T60SNC in a 16 kHz motor drive application?

A 16 Ω external gate resistor is specified in the datasheet for switching characterization at T_j = 150 °C, V_CC = 400 V, and I_C = 20 A. This value balances turn-off speed (250–300 ns t_d(off)) against gate oscillation risk and EMI. For 16 kHz operation, verify peak gate current does not exceed ±20 V rating and adjust downward only if layout parasitics permit stable edge control.

Can SIGC18T60SNC be directly substituted for SGP20N60 in a TO-220 assembly?

No - SIGC18T60SNC is a bare die; SGP20N60 is a fully packaged TO-220 device containing this die plus internal bonding, encapsulation, and leadframe. Substitution requires redesigning the entire power stage for die attach, isolation, and thermal interface - not a drop-in replacement.

What die attach materials are qualified for SIGC18T60SNC?

Infineon specifies electrically conductive glue or soft solder (e.g., SnPb or Pb-free Ag–Sn alloys) for collector-side bonding. Emitter pad bonding must use low-resistance, high-thermal-conductivity materials compatible with Al wire bonding (≤500 µm). Photoimide passivation permits standard epoxy and solder reflow profiles per JEDEC J-STD-020.

Is SIGC18T60SNC rated for repetitive short-circuit events?

Yes - the datasheet confirms short-circuit ruggedness under defined test conditions (V_CE = 600 V, T_j ≤ 150 °C), with guaranteed safe operation for ≥10 µs. However, each event causes cumulative degradation; Infineon recommends limiting such events to <1000 cycles over lifetime and implementing fast desaturation detection to minimize exposure.
