Product details

Overview

STGW40NC60W from STMicroelectronics is a 40 A, 600 V ultra-fast IGBT in TO-247 package, optimized for high-frequency switching in hard-switched and resonant topologies. It features low C_res/C_ies ratio (59 pF / 2900 pF ≈ 0.02), 2.1 V V_CE(sat) at 30 A/25 °C, and 126 nC total gate charge-enabling efficient operation in UPS inverters, induction heating, and PFC stages.

For engineers reviewing the STGW40NC60W datasheet, STGW40NC60W pinout, STGW40NC60W application, or STGW40NC60W equivalent, key selection criteria include its 600 V blocking capability, 230 A pulsed current rating, thermal resistance of 0.5 °C/W (j-case), and suitability for 20–100 kHz power conversion where low cross-conduction risk and fast turn-off (168 ns typical t_d(off)) are critical.

Technical Context

This IGBT employs ST's PowerMESH™ process to balance conduction loss and switching speed. Its low reverse transfer capacitance (C_res = 59 pF) minimizes Miller-induced turn-on risk, while the 1.9–2.5 V V_CE(sat) range across temperature supports stable thermal performance up to 150 °C junction.

The device is characterized for inductive-load switching with V_CC = 390 V, I_C = 30 A, and R_G = 10 Ω. Turn-off energy rises from 349 µJ (25 °C) to 750 µJ (125 °C), reflecting strong but temperature-sensitive tail-current behavior inherent to NPT IGBT architecture.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	600 V - supports 400 V AC input rectified systems with 50% safety margin
I_C (100 °C)	40 A continuous - defines usable current derating for heatsink-limited designs
V_CE(sat)	2.1 V @ 30 A, 25 °C - sets conduction loss baseline (≈ 63 W at full load)
C_res/C_ies	59 pF / 2900 pF = 0.020 - suppresses false turn-on during high dv/dt commutation
t_d(off)	168 ns typ. @ 25 °C - enables ≤100 kHz hard-switching with controlled dead-time
R_th(j-case)	0.5 °C/W - allows 250 W dissipation with ≤125 °C case-to-junction rise
E_off	349 µJ @ 25 °C - quantifies turn-off loss contribution in efficiency calculations

Pinout & Package

STGW40NC60W uses a standard 3-pin TO-247 package with isolated tab (collector-connected). The case is electrically tied to the collector terminal, requiring insulated mounting in most applications.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (left)	Collector (C)	Main high-side current path; electrically connected to metal tab-requires isolation from heatsink
Pin 2 (center)	Gate (G)	Control input; requires 15 V drive and low-inductance layout to manage 126 nC Q_g
Pin 3 (right)	Emitter (E)	Return path for load current; serves as reference for gate drive and current sensing

Key Features

Feature	Design Value
Low C_res/C_ies ratio	0.020 - reduces Miller feedback susceptibility in high dv/dt half-bridge legs
Ultra-fast switching	t_d(off) = 168 ns + t_f = 36 ns = 204 ns total - supports >50 kHz hard-switched SMPS
High pulsed current rating	I_CP = 230 A - accommodates short-term overload in welding and motor startup
Thermal robustness	T_j(max) = 150 °C with R_th(j-case) = 0.5 °C/W - enables compact thermal design under sustained load
ECOPACK® compliance	Lead-free second-level interconnect - meets RoHS and JEDEC JESD97 marking requirements

Applications

Induction Heating Systems

IC Role / Device Role / Timing Role: High-side switch in continuous conduction mode (CCM) boost converter; operates at 60–100 kHz.

Use Value: Fast turn-off (204 ns) minimizes switching loss at high frequency; low V_CE(sat) improves light-load efficiency.

Use Scenario: Primary-side switch controlling energy delivery to welding transformer in spot/mig welders.

IC Role / Device Role / Timing Role: Single-pulse or burst-mode switch handling 10–100 ms on-times at 500–2000 A peak.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-fast IGBT applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN40N60B3	Higher V_CE(sat) (2.4 V), lower C_res (45 pF), same 600 V/40 A rating	Better dv/dt immunity but higher conduction loss; less suitable for high-efficiency PFC	Prefer when circuit dv/dt exceeds 5 kV/µs and thermal headroom exists
Infineon IKW40N60H3	Lower E_off (220 µJ), higher g_fs (25 S), same package and voltage rating	Superior for >100 kHz soft-switching; reduced gate drive stiffness required	Choose for ZVS/ZCS topologies where turn-off loss dominates efficiency

Compared with IXGN40N60B3 and IKW40N60H3, STGW40NC60W offers the lowest C_res/C_ies ratio and best balance of conduction and switching loss below 80 kHz-making it optimal for cost-sensitive, thermally constrained hard-switched inverters and SMPS.

FAQ

Is STGW40NC60W still in active production?

No-ST has marked STGW40NC60W as obsolete per its July 2008 datasheet revision history. However, Aetrix Electronics maintains legacy inventory with full traceability and provides extended supply support including last-time buy coordination and cross-reference guidance for drop-in alternatives where technically validated.

What is the maximum gate-emitter voltage rating?

The absolute maximum V_GE is ±20 V, with recommended operating range of –5 V to +15 V. Exceeding +15 V risks accelerated gate oxide degradation, while negative bias below –5 V is unnecessary for turn-off and may increase gate drive complexity without benefit in standard hard-switched applications.

Can STGW40NC60W be used without a co-pack diode?

Yes-it is a standalone IGBT and requires an external anti-parallel freewheeling diode. The datasheet specifies test conditions using "a typical diode" (Figure 2), and ST does not offer a co-pack version of this part. Fast recovery or SiC Schottky diodes are recommended to minimize reverse recovery losses in high-frequency operation.

How does junction temperature affect V_CE(sat) performance?

V_CE(sat) increases with temperature: from 2.1 V at 25 °C to 2.5 V at 125 °C (Table 4). This positive temperature coefficient improves current sharing in parallel configurations but raises conduction loss by ~19% at max rated T_j, requiring thermal design margin to avoid runaway under sustained overload.
