STMicroelectronics STGW40NC60WD

Overview

STGW40NC60WD from STMicroelectronics is a 40 A, 600 V ultra-fast IGBT co-packaged with an ultra-fast free-wheeling diode in TO-247 package. It delivers low C_RES/C_IES ratio (59 pF / 2900 pF ≈ 0.02), 2.1 V V_CE(sat) at 30 A/25 °C, and 26 ns t_r(Voff), enabling high-frequency hard-switched and resonant topologies in industrial inverters and induction heating systems.

For engineers reviewing the STGW40NC60WD datasheet, STGW40NC60WD pinout, STGW40NC60WD application, or STGW40NC60WD equivalent, key selection criteria include its 600 V blocking voltage, 40 A continuous collector current at 100 °C, 0.5 °C/W IGBT junction-to-case thermal resistance, and integrated diode with 45 ns t_rr at 25 °C - all critical for high-efficiency SMPS and PFC designs.

Technical Context

This IGBT employs ST's PowerMESH™ process to optimize conduction loss versus switching speed trade-offs. Its internal structure integrates a matched ultra-fast diode with 2.4 V forward voltage at 30 A and 56 nC Q_rr, minimizing reverse recovery losses during commutation.

The device supports gate drive with ±20 V V_GE rating and exhibits 126 nC total gate charge at 390 V V_CE, enabling predictable turn-on/turn-off timing using standard 15 V gate drivers. Dynamic performance is characterized across temperature (25–125 °C) and load conditions (30 A, 390 V), with E_on = 302 µJ and E_off = 349 µJ at 25 °C.

Key Specifications

Pinout & Package

STGW40NC60WD uses a 3-pin TO-247 package with isolated tab (collector-connected). The metal tab serves as the collector terminal and must be electrically insulated from heatsink unless system-level grounding permits direct connection.

FAQ

Is STGW40NC60WD still in active production?

No - ST officially marked STGW40NC60WD as obsolete in July 2008 per revision history. However, Aetrix Electronics maintains verified legacy stock with full traceability, including original ST tube packaging and date-code documentation, supporting ongoing maintenance and replacement needs for installed equipment.

Can STGW40NC60WD replace STGW30NC60WD in existing designs?

Yes, with verification: both share identical TO-247 package, pinout, and gate drive requirements. STGW40NC60WD offers +10 A higher I_C rating and slightly lower V_CE(sat) (2.1 V vs. 2.2 V), improving thermal headroom. Layout changes are unnecessary, but gate resistor tuning may be needed due to 126 nC vs. 105 nC Q_g.

What is the maximum recommended gate resistor value for 50 kHz operation?

For reliable 50 kHz hard switching with minimal overshoot, ST recommends R_G = 10 Ω (as used in datasheet test conditions). At this value, measured t_d(off) = 168 ns and E_off = 349 µJ at 25 °C. Increasing R_G beyond 15 Ω significantly raises E_off and junction temperature without meaningful dv/dt reduction.

Does the co-packaged diode support synchronous rectification?

No - the integrated diode is optimized for freewheeling and reverse recovery, not synchronous rectification. Its 2.4 V V_F at 30 A and 56 nC Q_rr are incompatible with low-loss synchronous FET replacement. For synchronous designs, discrete SiC Schottky diodes or actively driven MOSFETs are required.
