Product details

Overview

STGW30NC120HD from STMicroelectronics is an N-channel 1200 V, 30 A, TO-247 packaged PowerMESH™ IGBT optimized for high-frequency soft-switching applications such as induction heating. It delivers low V_CE(sat) (≤2.75 V at 20 A, 125°C), low gate charge (110 nC), and fast switching with t_f = 312 ns (25°C) and t_f = 592 ns (125°C).

For engineers reviewing the STGW30NC120HD datasheet, STGW30NC120HD pinout, STGW30NC120HD application, or STGW30NC120HD equivalent, key selection criteria include its 1200 V blocking voltage, 30 A continuous current rating at 100°C, thermal resistance of 0.57 °C/W (j-case), and suitability for resonant inverter topologies requiring reduced turn-off tail current and low conduction loss.

Technical Context

This IGBT employs ST's patented strip layout for high-voltage robustness and optimized carrier lifetime control to achieve very fast fall time while maintaining low saturation voltage. Its high input impedance and low gate charge enable efficient gate drive with standard ±15 V logic-level controllers.

The device integrates a co-packaged fast recovery diode (V_F = 1.9 V at 20 A, 25°C; t_rr = 152 ns at 125°C) and supports operation up to 150°C junction temperature, making it suitable for thermally constrained industrial power converters where SOA and thermal impedance (R_th(j-case) = 0.57 °C/W) are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE(SAT)	≤2.75 V @ 20 A, 125°C - enables low conduction loss in high-temp induction heating inverters
Q_g	110 nC - reduces gate driver power requirement and improves switching efficiency
t_f	312 ns (25°C), 592 ns (125°C) - supports >50 kHz soft-switching operation with controlled tail current
R_th(j-case)	0.57 °C/W - allows 220 W dissipation at 25°C case temperature, easing heatsink sizing
V_CES	1200 V - rated for 3-phase rectified bus voltages up to 850 V DC with safety margin
I_C (cont.)	30 A @ T_C = 100°C - defines usable current in sealed enclosure thermal environments
E_off	4438 µJ @ 25°C - quantifies energy loss during zero-voltage switching transitions

Pinout & Package

Package: TO-247 (3-pin, single-ended, isolated tab). Pin 1 = Gate, Pin 2 = Collector, Pin 3 = Emitter. The metal tab is electrically connected to the collector and must be insulated from heatsink unless system topology requires common-collector configuration.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Voltage-driven input requiring ≤±25 V; low Q_ge (16 nC) enables fast Miller-free turn-on
Pin 2 (Collector)	High-side power output	Connected to DC bus or resonant tank; tab is collector potential - requires isolation or direct mounting per topology
Pin 3 (Emitter)	Power return / reference node	Serves as source for gate drive return and current sense reference; low-inductance layout critical for dI/dt stability

Key Features

Feature	Design Value
PowerMESH™ strip layout	Enables uniform current distribution and 1200 V breakdown with <2.75 V V_CE(SAT) at high temperature
Optimized for soft switching	Reduced t_f and tail current minimize E_off in ZVS/ZCS inverters without sacrificing V_CE(SAT)
Integrated fast recovery diode	Co-packaged diode with t_rr = 152 ns and Q_rr = 722 nC ensures matched thermal and dynamic behavior
ECOPACK® compliant	Lead-free second-level interconnect meets RoHS and JEDEC JESD97 marking requirements

Applications

Induction Heating Inverters

IC Role / Device Role / Timing Role: Main switching device in half-bridge configuration; handles full load current with ZVS-assisted turn-on and controlled turn-off tail.

Use Value: Low V_CE(SAT) and fast t_f reduce total losses by ≥18% vs. standard 1200 V IGBTs at 50 kHz, improving thermal margin.

Use Scenario: Online double-conversion UPS systems requiring high-reliability 1200 V switching under variable load and grid disturbance.

IC Role / Device Role / Timing Role: Output stage IGBT in three-phase inverter; operates with active clamp and overcurrent protection.

Use Value: 150°C max junction temperature and 135 A pulsed rating support short-term overload handling without derating.

Solar Central Inverters

Medium-Voltage Motor Drives

Use Scenario: Three-level NPC or T-type inverters converting DC from PV arrays to grid-synchronized AC at 690 V AC output.

IC Role / Device Role / Timing Role: High-side switch in multi-level topology; leverages low C_res (30 pF) for reduced capacitive turn-on loss.

Use Value: C_ies = 2510 pF and g_fs = 14 S enable stable gate control with minimal external R_G tuning.

Use Scenario: 400–690 V AC drives for pumps, compressors, and conveyors operating in harsh factory environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage IGBT applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN30N120B3	Higher V_CE(SAT) (3.2 V typ.), higher Q_g (150 nC), slower t_f (750 ns)	Less suited for >40 kHz soft switching; better for hard-switched 15–25 kHz motor drives	Select when lower gate drive complexity is prioritized over switching loss minimization
Infineon IKW30N120T2	Lower V_CE(SAT) (2.1 V), faster t_f (220 ns), but no integrated diode	Requires external diode selection; superior for discrete-diode ZVS designs with precise recovery control	Select when diode recovery parameters must be independently optimized and board space permits separate placement

Compared with IXGN30N120B3 and IKW30N120T2, STGW30NC120HD offers the best balance of low conduction loss, fast turn-off, and integrated diode matching - ideal for compact, thermally constrained induction heating modules where co-packaging simplifies layout and thermal coupling.

FAQ

What gate resistor value is recommended for STGW30NC120HD in a 50 kHz induction heating half-bridge?

A gate resistor of 10 Ω is specified in the datasheet for switching characterization (t_f, E_off) at 25°C and 125°C. For 50 kHz operation, 10–15 Ω balances turn-on speed and dV/dt control; lower values risk shoot-through in hard-commutated phases, while higher values increase switching loss beyond acceptable limits.

Does STGW30NC120HD require negative gate voltage for reliable turn-off?

No. The device is fully compatible with 0 V / +15 V gate drive. Its V_GE(th) range (3.75–5.75 V) and low IGES (±100 nA) ensure clean turn-off with zero-volt gate bias. Negative voltage is unnecessary and not recommended unless system-level noise immunity demands it - in which case –5 V is the absolute maximum per V_GE rating.

Can the integrated diode be used for freewheeling in a three-phase motor drive?

Yes. The co-packaged diode has V_F = 1.9 V (25°C) and t_rr = 152 ns (125°C), making it suitable for standard 6-step or SVM motor drives up to 4 kHz. However, for field-oriented control with high di/dt or regenerative braking, verify reverse recovery behavior against your specific bus voltage and load inductance using Figure 20 waveforms.

Is STGW30NC120HD qualified for automotive underhood use?

No. This part is not automotive-grade: it lacks AEC-Q101 qualification, has no guaranteed 175°C operation, and is not screened for automotive reliability testing. ST explicitly states non-automotive use in the datasheet disclaimer. For underhood applications, consider ST's Automotive PowerMESH™ variants like the STGW40H120DF2.
