STMicroelectronics STGW30NC60KD

Overview

STGW30NC60KD from STMicroelectronics is a 30 A, 600 V short-circuit rugged IGBT co-packaged with an ultra-fast freewheeling diode in TO-247 package, featuring 2.1 V V_CE(sat) at 20 A/25°C, 10 µs short-circuit withstand time, and low C_res/C_ies ratio - deployed in high-frequency motor drive inverters.

For engineers reviewing the STGW30NC60KD datasheet, STGW30NC60KD pinout, STGW30NC60KD application, or STGW30NC60KD equivalent, key selection criteria include V_CE(sat) stability over temperature, diode reverse recovery performance (t_rr = 40 ns @ 25°C), gate charge (Q_g = 96 nC), thermal resistance (R_thj-case = 0.625 °C/W), and short-circuit robustness under 12 V gate drive.

Technical Context

This IGBT employs ST's PowerMESH™ process to balance conduction loss and switching speed. It delivers 2.1 V typical V_CE(sat) at 20 A/25°C and maintains 1.9 V at 125°C, while its 46 pF C_res and 2170 pF C_ies yield a low 0.021 C_res/C_ies ratio, minimizing cross-conduction risk in bridge configurations.

The integrated diode exhibits 2.6 V forward voltage at 20 A/25°C and 1.6 V at 125°C, with t_rr = 40 ns and Q_rr = 50 nC under standard test conditions (V_R = 50 V, di/dt = 100 A/µs), enabling clean commutation in hard-switched inverters up to 20 kHz.

FAQ

What is the maximum continuous collector current at 100°C case temperature?

The STGW30NC60KD supports 28 A continuous collector current at T_C = 100°C, as specified in Table 2 of the datasheet. This derating reflects thermal limitations of the TO-247 package and internal chip design, and must be respected in heatsink-limited applications such as enclosed motor drives.

Is the integrated diode rated for 30 A RMS or peak current?

The co-packaged diode is rated for 30 A RMS forward current at T_C = 25°C (Table 2), matching the IGBT's 30 A rating. Its surge capability reaches 120 A for 10 ms (sinusoidal), confirming suitability for motor-start transient currents without external diode supplementation.

Can STGW30NC60KD operate reliably with 12 V gate drive?

Yes - the device is characterized for short-circuit withstand at V_GE = 12 V (t_scw = 10 µs), and V_GE(th) ranges from 4.5 V to 6.5 V. A 12 V drive ensures sufficient overdrive margin above threshold while avoiding gate oxide stress associated with ±20 V absolute maximum ratings.

Does the TO-247 package have a conductive mounting tab?

Yes - the metal tab is electrically connected to the collector terminal, as confirmed by the internal schematic (Figure 1) and mechanical drawings. Electrical isolation via mica washer or insulating pad is mandatory when mounting to grounded heatsinks to prevent short circuits.
