STMicroelectronics STGWT40HP65FB

Overview

STGWT40HP65FB from STMicroelectronics is a trench gate field-stop IGBT in the HB series, rated 650 V / 40 A (continuous at T_C = 100 °C), with co-packed anti-parallel diode, V_CE(sat) = 1.6 V (typ. @ I_C = 40 A, T_J = 25 °C), and R_thJC = 0.53 °C/W for the IGBT die - used in high-efficiency PFC stages of industrial AC-DC converters.

For engineers reviewing the STGWT40HP65FB datasheet, STGWT40HP65FB pinout, STGWT40HP65FB application, or STGWT40HP65FB equivalent, key selection criteria include its minimized tail current, tight V_CE(sat) distribution (±0.2 V), positive temperature coefficient enabling safe paralleling, and integrated diode with t_rr = 140 ns (T_J = 25 °C) for reduced switching loss in hard-switched topologies.

Technical Context

This IGBT employs a proprietary trench gate field-stop structure optimized for balanced conduction and switching losses across 20–100 kHz PFC operating ranges. Its slightly positive V_CE(sat) temperature coefficient (1.7 V @ 125 °C, 1.8 V @ 175 °C) and low thermal resistance enable stable current sharing in parallel configurations without external emitter resistors.

The integrated fast recovery diode features t_rr = 140 ns (25 °C) and Q_rr = 21 nC under 1000 A/µs di/dt, with soft recovery behavior confirmed by dI_rr/dt = 430 A/µs - critical for minimizing voltage overshoot and EMI in boost PFC circuits.

Key Specifications

Pinout & Package

STGWT40HP65FB uses the TO-3P package: insulated metal tab (collector), two leads (gate and emitter), with case isolation voltage >2500 V_RMS. The metal tab serves as the collector terminal and primary thermal path to heatsink.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, designing and manufacturing analog, digital, and mixed-signal ICs, power devices, and microcontrollers for industrial, automotive, and consumer markets.

The HB series IGBTs are engineered specifically for high-efficiency, medium-frequency power conversion - targeting PFC, motor drives, and UPS systems where conduction-loss sensitivity and switching-energy predictability are equally critical.

FAQ

What is the maximum recommended gate resistor value for reliable turn-off?

The datasheet specifies R_G = 5 Ω for all switching energy and timing measurements. Using R_G > 10 Ω increases td(off) and tf beyond 142 ns and 27 ns respectively, risking shoot-through in half-bridge configurations. For robust operation with 15 V gate drive, 4.7–5.6 Ω is the validated range ensuring E_off stability and thermal margin.

Can STGWT40HP65FB be used in a totem-pole PFC configuration?

Yes - its co-packed diode has soft reverse recovery (dI_rr/dt = 430 A/µs) and low Q_rr = 21 nC, enabling bidirectional conduction in totem-pole topologies. However, the diode's 5 A continuous rating limits operation to ≤ 3.3 kW at 230 VAC; forced-air cooling or paralleling is required above that level.

Is the TO-3P package lead-free and RoHS-compliant?

Yes - STGWT40HP65FB is manufactured in an ECOPACK®2-compliant TO-3P package, meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. The device carries the "ECOPACK2" marking on the package and is qualified for lead-free soldering up to 260 °C peak temperature per J-STD-020.

What is the safe operating area (SOA) limitation at 175 °C junction temperature?

At T_J = 175 °C, the forward-biased SOA is limited to 40 A at V_CE ≤ 200 V for pulse widths ≤ 10 ms. Beyond this, secondary breakdown risk increases sharply; the device must be operated within the derated curve shown in Figure 9 of the datasheet, with strict attention to gate drive strength and layout inductance to avoid localized hot spots.
