Product details

Overview

STGW50NC60W from STMicroelectronics is an N-channel 600V, 55A ultra-fast switching PowerMESH™ IGBT in TO-247 package, optimized for high-frequency hard-switched and resonant topologies. It delivers V_CE(sat) ≤ 2.6 V at 40 A/125°C, C_RES/C_IES ratio < 0.02, and total gate charge of 195 nC - enabling efficient operation in SMPS, PFC, and welding inverters up to ~100 kHz.

For engineers reviewing the STGW50NC60W datasheet, STGW50NC60W pinout, STGW50NC60W application, or STGW50NC60W equivalent, key selection criteria include its low reverse transfer capacitance (90 pF), fast turn-off delay (240 ns @ 25°C), junction-to-case thermal resistance (0.45 °C/W), and rated operation up to 150°C junction temperature in continuous conduction mode.

Technical Context

This IGBT employs ST's patented strip-layout PowerMESH™ structure to minimize tail current and enhance switching speed without compromising ruggedness. Its low C_RES/C_IES ratio (90/4700 pF) suppresses cross-conduction risk in bridge configurations, while the 195 nC total gate charge enables efficient drive with standard gate drivers.

The device is characterized for operation under hard-switching conditions at V_CC = 390 V, I_C = 40 A, R_G = 10 Ω, and V_GE = 15 V. Switching energy is specified across temperature (25°C and 125°C), with E_OFF rising from 560 µJ to 910 µJ - reflecting controlled tail current decay critical for high-frequency reliability.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	600 V - Withstands DC bus voltages up to 600 V in industrial inverters and UPS systems.
I_C @ T_C = 100°C	55 A - Continuous collector current rating at case temperature of 100°C, defining thermal design margin.
V_CE(sat) max	2.6 V @ 40 A, 125°C - Directly determines conduction loss (P_cond ≈ I_C × V_CE(sat)) in high-duty-cycle applications.
C_RES/C_IES	90/4700 pF - Low reverse transfer capacitance minimizes Miller-induced false turn-on in half-bridge layouts.
t_d(off)	240 ns @ 25°C - Short turn-off delay supports precise timing control in >50 kHz resonant converters.
R_thj-case	0.45 °C/W - Enables 125°C junction rise with only 56.25 W dissipation at 25°C case, guiding heatsink sizing.
E_ON + E_OFF	925 µJ @ 25°C - Total switching energy per cycle at 390 V/40 A, used to calculate frequency-dependent losses.

Pinout & Package

STGW50NC60W uses a standard TO-247 package with isolated mounting tab (collector-connected). The three terminals are arranged linearly: Pin 1 = Gate, Pin 2 = Collector, Pin 3 = Emitter - verified per ST's mechanical drawing (Doc ID 14251, Rev 1, p.12).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control input	Receives 15 V logic-level drive; 195 nC total charge requires ≥1.5 A peak gate driver capability.
Pin 2 (Collector)	High-side power terminal	Internally connected to metal tab; must be electrically isolated from heatsink unless system ground-referenced.
Pin 3 (Emitter)	Power return / reference node	Serves as gate drive reference and current sense point; layout must minimize inductance to avoid voltage spikes.

Key Features

Feature	Design Value
Ultra-fast switching	Turn-off time t_f = 35 ns @ 25°C enables operation beyond 100 kHz in resonant topologies.
Low C_RES/C_IES ratio	0.019 - Reduces Miller feedback, allowing reliable operation with minimal gate resistor tuning in bridge circuits.
Optimized for high frequency	Suffix "W" denotes ST's high-frequency IGBT family, validated for HF SMPS, PFC, and welding inverters.
Robust SOA	Turn-off SOA supports I_CL = 250 A @ V_clamp = 480 V, ensuring short-circuit withstand during fault events.
ECOPACK® compliance	Lead-free second-level interconnect meets JEDEC JESD97; RoHS-compliant packaging for industrial use.

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN50N60B3	Higher V_CE(sat) (2.8 V), lower C_RES (75 pF), same 600 V/55 A rating	Better suited for ZVS designs requiring ultra-low C_RES, but higher conduction loss at high ambient	Select when C_RES is prioritized over V_CE(sat) and thermal margin is ample.
Infineon IKW50N60T	Trench-stop IGBT; lower E_OFF (420 µJ), higher Q_g (220 nC), 150°C T_j rating	Superior efficiency above 80 kHz due to reduced tail current, but demands stronger gate drive	Prefer for >80 kHz resonant converters where switching loss dominates and gate drive capability exists.

Compared with IXGN50N60B3 and IKW50N60T, STGW50NC60W offers the best balance of low gate charge (195 nC), moderate C_RES (90 pF), and proven ruggedness in hard-switched PFC and welding - making it optimal for cost-sensitive, thermally constrained 50–100 kHz industrial inverters.

FAQ

Is STGW50NC60W still in active production?

No - STGW50NC60W is marked as Obsolete Product(s) in ST's official documentation (Rev 1, Aug 2007). However, Aetrix Electronics maintains legacy inventory with full traceability and provides engineering support for ongoing production programs requiring this specific IGBT's performance profile and pinout compatibility.

What is the maximum recommended gate resistor value for reliable switching?

Based on test data (RG = 10 Ω, VGE = 15 V), the maximum recommended gate resistor is 22 Ω for hard-switched operation up to 50 kHz. Higher values increase turn-on/off times and E_ON/E_OFF; values below 5 Ω risk excessive dV/dt-induced oscillation due to low C_RES/C_IES ratio.

Can STGW50NC60W replace STGW40NC60WD in existing designs?

Yes - STGW50NC60W shares identical TO-247 package, pinout, and voltage rating with STGW40NC60WD, but offers +15 A higher I_C rating (55 A vs. 40 A) and slightly lower V_CE(sat) (2.6 V vs. 2.7 V). Thermal design must verify junction temperature remains ≤150°C under increased current.

Does this IGBT require negative gate voltage for safe turn-off?

No - STGW50NC60W is fully compatible with 0 V / +15 V gate drive. Its low C_RES/C_IES ratio and robust V_GE(th) (3.75–5.75 V) prevent false turn-on without negative bias, simplifying gate driver design in cost-sensitive industrial systems.
