Product details

Overview

STGWA40H120F2 from STMicroelectronics is a 1200 V, 40 A trench-gate field-stop IGBT in the H-series optimized for high-frequency converters, featuring V_CE(sat) = 2.1 V (typ.) at I_C = 40 A, 5 µs short-circuit withstand time at T_J = 150 °C, and R_thJC = 0.32 °C/W - deployed in photovoltaic inverters and UPS systems.

For engineers reviewing the STGWA40H120F2 datasheet, STGWA40H120F2 pinout, STGWA40H120F2 application, or STGWA40H120F2 equivalent, key selection criteria include switching energy (E_on = 1.81 mJ, E_off = 2.46 mJ at T_J = 175 °C), safe paralleling capability, and TO-247 long leads thermal performance.

Technical Context

This IGBT employs a proprietary trench gate field-stop structure to balance conduction and switching losses, enabling operation up to 20 kHz in hard-switched topologies. Its slightly positive V_CE(sat) temperature coefficient and tight parameter distribution support stable parallel operation without current-sharing resistors.

Dynamic performance is characterized by low C_ies (3200 pF), C_res (80 pF), and total gate charge Q_g = 158 nC, enabling fast turn-on (t_d(on) = 36 ns) and controlled turn-off (t_d(off) = 161 ns) under 175 °C junction conditions with 10 Ω gate resistance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	1200 V - supports DC-link voltages up to 960 V in 3-phase PFC and inverter stages
I_C (T_C = 100 °C)	40 A - continuous rating usable in forced-air-cooled industrial power modules
V_CE(sat) (T_J = 175 °C)	2.5 V - enables <100 W conduction loss at 40 A, critical for thermal budget in compact designs
t_sc	5 µs - provides robust short-circuit protection window for fault detection and shutdown
R_thJC	0.32 °C/W - allows 146 W power dissipation at ΔT = 46.7 °C case-to-junction rise
E_off (T_J = 175 °C)	2.46 mJ - defines minimum snubber sizing and heatsink requirements in high-frequency switching
Q_g	158 nC - determines gate driver peak current (≥1.6 A @ 10 ns rise) and drive power

Pinout & Package

TO-247 long leads package with isolated tab (collector), standard 3-pin layout optimized for mechanical stability and thermal transfer in high-power PCB mounting. Tab is electrically connected to collector (pin 2).

Pin/Terminal	Circuit Role	Design Meaning
G (Pin 1)	Gate	Control terminal requiring ±20 V absolute max; 158 nC total charge dictates gate resistor selection for dV/dt control
C (Pin 2, TAB)	Collector	Main high-side power terminal; tab must be mounted to heatsink with electrically insulating thermal interface
E (Pin 3)	Emitter	Reference node for gate drive and current sensing; low-inductance layout essential for switching stability

Key Features

Feature	Design Value
Trench gate field-stop structure	Reduces tail current and switching losses while maintaining 1200 V blocking capability
Slightly positive V_CE(sat) tempco	Enables inherent current balancing in paralleled configurations without external ballasting
5 µs short-circuit withstand time	Supports reliable overcurrent protection implementation with microsecond-level response
Low C_res (80 pF)	Minimizes Miller-induced turn-on risk and reduces gate drive power consumption
R_thJC = 0.32 °C/W	Permits higher power density in space-constrained industrial power converters

Applications

Photovoltaic Inverters

Uninterruptible Power Supply

Use Scenario: Three-phase string inverters converting DC from solar arrays to grid-synchronized AC at 16–20 kHz switching frequency.

IC Role / Device Role / Timing Role: High-side IGBT in NPC or T-type inverter leg handling 40 A RMS output current at 1200 V DC-link.

Use Value: Low E_off (2.46 mJ) and minimized tail current reduce thermal stress during high-frequency modulation, extending lifetime under partial-load cycling.

Use Scenario: Online double-conversion UPS systems delivering clean 50/60 Hz output with zero transfer time during mains failure.

IC Role / Device Role / Timing Role: Inverter-stage switch managing bidirectional power flow between battery bank and AC output stage.

Use Value: 5 µs short-circuit tolerance enables robust fault containment during load surges or downstream short events without desaturation circuit complexity.

Welding Equipment

Power Factor Correction

Use Scenario: IGBT-based inverter welders generating high-current DC or pulsed output (200–500 A) with rapid duty-cycle transitions.

IC Role / Device Role / Timing Role: Primary switching device in resonant or hard-switched DC-link chopper controlling arc energy delivery.

Use Value: Safe paralleling capability allows scalable current handling using multiple STGWA40H120F2 units without derating or matching.

Use Scenario: Active front-end rectifiers in industrial motor drives correcting displacement and distortion power factor to >0.99.

IC Role / Device Role / Timing Role: Boost switch operating at 15–25 kHz in three-phase Vienna or boost PFC topologies.

Use Value: Tight V_CE(sat) distribution (±0.1 V) ensures consistent conduction loss across multi-phase legs, improving system efficiency uniformity.

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 IXGN40N120B3	Higher V_CE(sat) (2.7 V @ 40 A), lower E_off (1.9 mJ), TO-247 package without long leads	Limited thermal margin in high-ambient environments due to higher R_thJC (0.45 °C/W)	Prefer when lower turn-off loss dominates over conduction loss and board-level heatsinking is constrained
Infineon IKW40N120H3	Identical V_CE(sat) (2.1 V), higher Q_g (180 nC), same TO-247 long leads footprint	Requires stronger gate driver (≥1.8 A peak) and larger gate resistor for equivalent dV/dt control	Choose when design already uses Infineon ecosystem tools and requires identical mechanical fit with enhanced ruggedness

Compared with IXGN40N120B3 and IKW40N120H3, STGWA40H120F2 delivers the lowest combined conduction–switching loss trade-off at 175 °C, validated by its 2.5 V V_CE(sat) and 2.46 mJ E_off, making it optimal for thermally dense, high-reliability converter designs.

FAQ

What is the maximum gate-emitter voltage rating for STGWA40H120F2?

The absolute maximum V_GE is ±20 V, with recommended operating range of –10 V to +15 V. Exceeding +15 V increases gate oxide stress and leakage; negative bias below –10 V risks gate threshold shift. Gate drive circuits must limit transient overshoot using clamping diodes or active regulation.

Does STGWA40H120F2 include an integrated freewheeling diode?

No - STGWA40H120F2 is a standalone IGBT. The co-packed STGW40H120DF2 variant integrates a matched anti-parallel diode, but this part requires external diode selection. Diode recovery characteristics must be verified against IGBT turn-off timing to avoid shoot-through.

How does the TO-247 long leads variant differ electrically from standard TO-247?

Electrical ratings are identical; the long leads version (STGWA40H120F2) improves mechanical robustness and solder joint reliability in high-vibration environments. Lead length increase (L = 19.92 mm vs. 14.5 mm) adds ~1.5 nH parasitic inductance, requiring localized gate loop minimization.

Can STGWA40H120F2 operate reliably at 175 °C junction temperature continuously?

Yes - rated T_J range is –55 to +175 °C, with all key parameters (V_CE(sat), E_off, t_sc) specified at 175 °C. Continuous operation requires maintaining case temperature ≤100 °C per derating curves, supported by R_thJC = 0.32 °C/W and proper heatsink interface.
