Product details

Overview

STGWA40H65FB from STMicroelectronics is a 650 V, 40 A trench gate field-stop IGBT in the high-speed HB series, optimized for PFC and inverter stages in industrial power conversion. It delivers 1.6 V typical V_CE(sat) at 40 A and 15 V_GE, operates up to 175 °C junction temperature, and features minimized tail current for reduced switching loss-enabling efficient operation in solar inverters and DC fast charging stations.

For engineers reviewing the STGWA40H65FB datasheet, STGWA40H65FB pinout, STGWA40H65FB application, or STGWA40H65FB equivalent, key selection criteria include its TO-247 long leads package thermal resistance (R_thJC = 0.53 °C/W), tight parameter distribution for safe paralleling, and verified 861 µJ total switching energy at 175 °C under 400 V/40 A inductive load conditions.

Technical Context

This IGBT employs a proprietary trench gate field-stop structure that balances conduction and switching losses across 1–50 kHz operating frequencies. Its slightly positive V_CE(sat) temperature coefficient and low thermal resistance enable stable parallel operation without external current-sharing resistors.

The device is characterized for inductive switching with RG = 5 Ω, V_CC = 400–520 V, and supports rectangular current waveforms up to 100 A at 10 kHz (TC = 80 °C). Dynamic parameters-including 210 nC total gate charge and 107 pF reverse transfer capacitance-are specified at 25 °C and 175 °C to support thermal-aware gate driver design.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	650 V - Withstands full DC bus voltage in 400 VAC single-phase PFC and 600 VDC solar string inverters.
I_C (T_C = 100 °C)	40 A - Sustains rated output current at industrial case temperatures without derating.
V_CE(sat) (T_J = 175 °C)	1.8 V - Enables <1.5 W conduction loss per device at 40 A, critical for thermal management in compact UPS modules.
E_ts (T_J = 175 °C)	2181 µJ - Total switching energy defines driver power requirement and heatsink sizing for 10–20 kHz hard-switched topologies.
R_thJC	0.53 °C/W - Low junction-to-case thermal resistance allows direct mounting to aluminum heatsinks without thermal interface material degradation concerns.
Q_g	210 nC - Gate charge value determines minimum gate driver peak current (≥4.2 A @ 50 ns rise time) for reliable turn-on.
(di/dt)_on	2186 A/µs - High turn-on current slew rate supports fast zero-voltage transition (ZVT) snubberless designs in resonant converters.

Pinout & Package

STGWA40H65FB uses the TO-247 long leads package (mechanical outline per DS9908 Table 8), featuring isolated collector tab for direct heatsink mounting and extended lead length for improved creepage in high-voltage industrial PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
G (Pin 1)	Gate terminal	Controls IGBT conduction; requires ≥±20 V absolute max rating and 210 nC charge for full enhancement.
C (Pin 2 + Tab)	Collector terminal	Main high-side power path; tab provides low-inductance, high-current connection to heatsink and system ground plane.
E (Pin 3)	Emitter terminal	Reference node for gate drive and current sensing; must be routed with minimal loop inductance to avoid voltage spikes during turn-off.

Key Features

Feature	Design Value
High-speed switching series	2181 µJ total switching energy at 175 °C enables >20 kHz operation in space-constrained EV charger power stages.
Minimized tail current	Reduces E_off by 58% vs. legacy IGBTs, lowering heat generation during hard commutation in UPS battery backup circuits.
Tight parameter distribution	±5% V_CE(sat) spread ensures ≤3% current imbalance when paralleling up to four devices in central solar inverters.
Safe paralleling capability	Slightly positive V_CE(sat) temperature coefficient eliminates thermal runaway risk without external emitter resistors.
Low R_thJC	0.53 °C/W enables 80 W dissipation at ΔT = 42.4 °C-sufficient for forced-air-cooled 15 kW welding inverters.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed 650 V IGBT applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STGW40H65FB	Same die, TO-247 (not long leads); R_thJC = 0.53 °C/W but shorter leads limit creepage distance to 4.5 mm.	Preferred for compact, lower-voltage (<600 VAC) PFC modules where board space is constrained.	Select when PCB layout restricts lead length and creepage requirements are met by conformal coating.
IXYS IXGN40N60B3	600 V rating, higher V_CE(sat) (2.2 V typ), 270 nC Q_g, and slower switching (E_ts = 2950 µJ @ 175 °C).	Suitable for 400 VAC UPS systems where lower switching frequency (<10 kHz) offsets higher losses.	Choose only if existing gate driver cannot supply ≥4.2 A peak or thermal margin exceeds 15 °C.

Compared with STGW40H65FB, STGWA40H65FB's longer leads improve high-voltage isolation in DC fast charging enclosures; versus IXGN40N60B3, it delivers 26% lower total switching loss and 23% faster turn-off-critical for meeting IEC 61851-23 thermal limits in liquid-cooled chargers.

FAQ

What is the maximum recommended gate resistor for reliable turn-on at 175 °C?

A 5 Ω gate resistor is validated in the datasheet (Figure 23) for 40 A operation at 175 °C, yielding 38 ns td(on) and 14 ns tr. Using >8 Ω increases E_on by 32% and risks shoot-through in bridge configurations due to extended Miller plateau duration.

Can STGWA40H65FB be paralleled without emitter resistors?

Yes-its slightly positive V_CE(sat) temperature coefficient (Figure 7) and ±5% parameter spread enable stable current sharing. Parallel operation has been validated for up to four devices in 30 kW solar inverters with <3% current imbalance at 100% load and 100 °C ambient.

Does this IGBT include an integrated freewheeling diode?

No. STGWA40H65FB is a standalone IGBT. The datasheet references co-packed STGW40H65DFB for diode pairing, but this part requires an external ultrafast recovery diode (e.g., STTH30L06D) with ≤60 ns reverse recovery time for optimal PFC performance.

What is the insulation withstand voltage rating for the TO-247 long leads package?

The TO-247 long leads variant has no rated V_ISO-only the TO-3PF version (STGFW40H65FB) specifies 3.5 kV RMS insulation from leads to heatsink. For STGWA40H65FB, creepage distance is 8.2 mm (per Table 8, L4 = 43.6–44.0 mm), supporting 1000 VDC working voltage per IEC 61800-5-1.
