STMicroelectronics STGWT30H60DFB

Overview

STGWT30H60DFB from STMicroelectronics is a 600 V, 30 A trench-gate field-stop IGBT with integrated ultra-fast soft-recovery antiparallel diode in TO-3P package. It delivers low saturation voltage (1.55 V typ. @ IC = 30 A), minimized tail current, and positive V_CE(sat) temperature coefficient for safe paralleling-optimized for photovoltaic inverters and high-frequency converters.

For engineers reviewing the STGWT30H60DFB datasheet, STGWT30H60DFB pinout, STGWT30H60DFB application, or STGWT30H60DFB equivalent, key selection criteria include switching energy (E_on = 383 µJ / E_off = 293 µJ @ TJ = 25 °C), reverse recovery performance (t_rr = 53 ns, Q_rr = 384 nC), thermal resistance (R_thJC = 0.58 °C/W for IGBT), and TO-3P mechanical compatibility in high-power industrial modules.

Technical Context

This IGBT employs ST's proprietary trench gate field-stop structure to balance conduction loss (V_CE(sat) = 1.55 V) and switching loss (E_ts = 676 µJ), targeting efficiency-critical frequency converters operating up to 20 kHz. Its integrated diode features soft recovery (dI_rr/dt = 788 A/µs) and low reverse recovery charge (Q_rr = 384 nC), reducing voltage overshoot and EMI.

The device exhibits a slightly positive V_CE(sat) temperature coefficient and tight parameter distribution-enabling stable parallel operation without current-sharing resistors. Thermal design is supported by low junction-to-case resistance (0.58 °C/W for IGBT, 2.08 °C/W for diode) and rated junction temperature up to 175 °C.

Key Specifications

Pinout & Package

STGWT30H60DFB uses the TO-3P package-a through-hole, insulated metal-tab power package with three leads arranged in line (1–2–3). The tab is electrically connected to the collector (pin 1), enabling direct heatsink mounting with electrical isolation.

FAQ

What is the maximum gate-emitter voltage rating for STGWT30H60DFB?

The absolute maximum gate-emitter voltage is ±20 V for continuous operation and ±30 V for transient conditions, per Table 1 of DS10467 Rev 4. Exceeding ±20 V continuously risks gate oxide degradation; gate drivers must clamp transients above ±30 V using Zener diodes or active clamping circuits.

Does STGWT30H60DFB require a negative gate voltage for reliable turn-off?

No-STGWT30H60DFB is fully specified for 0 V to +15 V gate drive (V_GE(th) = 5–7 V). Negative gate bias is not required for robust turn-off; however, –5 V to –10 V may improve noise immunity in high-dv/dt environments like multi-level inverters.

How does the integrated diode's reverse recovery compare at elevated temperature?

At T_J = 175 °C, t_rr increases to 104 ns and Q_rr rises to 1352 nC (Table 6), more than tripling versus 25 °C values. This necessitates conservative snubber design and gate resistor tuning to manage increased voltage overshoot during diode commutation.

Can STGWT30H60DFB be paralleled with STGW30H60DFB in the same design?

No-despite identical electrical specs, TO-3P (STGWT30H60DFB) and TO-247 (STGW30H60DFB) packages have different thermal paths, lead inductances, and mounting mechanics. Paralleling across packages causes unequal current sharing and thermal runaway; only units in identical packages should be paralleled.
