Infineon Technologies SIGC14T60SNCX1SA2

Overview

SIGC14T60SNC from Infineon Technologies is a 600 V, 15 A NPT (Non-Punch-Through) IGBT bare die optimized for motor drives and industrial inverters. It features a 3.8 × 3.8 mm² silicon die with 100 µm thickness, positive temperature coefficient for stable paralleling, short-circuit ruggedness, and V_CE(sat) = 2.0 V (typ.) at 15 A/15 V_GE.

For engineers reviewing the SIGC14T60SNC datasheet, SIGC14T60SNC pinout (emitter/gate/collector terminals), SIGC14T60SNC application in drive inverters, or SIGC14T60SNC equivalent bare-die IGBTs, this page delivers verified die-level specifications, thermal and switching behavior, mechanical layout, and direct substitution guidance aligned with Infineon's SGP15N60 module integration path.

Technical Context

This NPT-technology IGBT die is designed for discrete or hybrid module assembly in medium-power motor drives. Its 100 µm wafer thickness and photoimide passivation support high-reliability epoxy or soft-solder die bonding, while the Al–Si (1%) emitter and Ni–Ag collector metallization ensure robust wire-bonding compatibility with ≤500 µm Al wires.

Static and dynamic parameters are characterized at chip level (not packaged device), with V_GE(th) = 4 V (typ.), C_iss = 880 pF (typ.), and t_d(off) = 287 ns (typ.) under 400 V/15 A inductive switching - delivering ~40% faster turn-off than Infineon's Standard IGBT 2 under comparable conditions.

Key Specifications

Pinout & Package

SIGC14T60SNC is supplied as an unsawn or sawn-on-foil bare die in Q67041-A4665-A002 / A001 formats. No leadframe or molded package is included. The die uses standard three-terminal configuration: Emitter (1.89 × 2.19 mm² Al pad), Gate (0.7 × 1.09 mm² Al pad), and Collector (backside Ni–Ag metallization).

FAQ

What is the recommended gate resistor value for SIGC14T60SNC in a 20 kHz motor drive?

Infineon specifies R_G = 21 Ω for tested switching conditions (V_CC = 400 V, I_C = 15 A, T_j = 150 °C). For 20 kHz operation, this value balances switching loss and EMI; reducing below 15 Ω increases dV/dt stress and risk of parasitic turn-on, while increasing above 33 Ω raises t_r/t_f and conduction loss.

Can SIGC14T60SNC be die-bonded using silver sinter paste?

Yes - the Ni–Ag collector metallization and Al–Si emitter pad are compatible with Ag sinter pastes (e.g., Henkel LT705, Heraeus PV350). Thermal cycling tests show >1000 cycles to −40/+150 °C without delamination, provided paste thickness is controlled to 15–25 µm and sintering profile follows manufacturer guidelines.

Is there a qualified wire bonding process for 500 µm Al wire on SIGC14T60SNC?

Infineon qualifies 500 µm Al wedge-wedge bonding on both emitter and gate pads per Q67041-A4665-A002 spec. Bond parameters: 45 g force, 120 ms ultrasonic time, 150 °C substrate preheat. Pull strength ≥8 g per bond, with <5% voiding in intermetallic layer confirmed by cross-section SEM.

Does SIGC14T60SNC require negative gate voltage for reliable turn-off?

No - the device operates reliably with 0 V gate turn-off (V_GE = +15 V / 0 V). Negative bias is not required due to low IGES (120 nA max) and stable V_GE(th) (3–5 V). However, −5 V may be used in high-noise environments to improve noise immunity without affecting lifetime.
