STMicroelectronics STGF20H60DF

Overview

STGF20H60DF from STMicroelectronics is a 600 V, 20 A trench gate field-stop IGBT with integrated soft/fast recovery antiparallel diode in TO-220FP package. It delivers 1.6 V typical V_CE(sat) at 20 A/25 °C, 175 °C maximum junction temperature, and 5 µs short-circuit withstand time - optimized for high-efficiency PFC converters and UPS inverters operating at elevated temperatures.

For engineers reviewing the STGF20H60DF datasheet, STGF20H60DF pinout, STGF20H60DF application, or STGF20H60DF equivalent, key selection criteria include its tight V_CE(sat) distribution (±0.2 V), low R_thJC of 4 °C/W (IGBT), 115 nC total gate charge, and validated safe paralleling capability under industrial thermal stress.

Technical Context

This IGBT employs ST's proprietary trench gate field-stop structure to balance conduction and switching losses - achieving 209 µJ turn-on and 261 µJ turn-off energy at 400 V/20 A/25 °C. Its slightly positive V_CE(sat) temperature coefficient enables stable current sharing across parallel devices without external ballasting resistors.

The integrated diode features 90 ns reverse recovery time (T_J = 25 °C) and 110 nC Q_rr, with soft recovery characteristics confirmed by <1.3 A reverse recovery peak current. Switching performance remains robust at 175 °C, where t_d(off) increases only 4 ns and E_off rises to 416 µJ.

Key Specifications

Pinout & Package

STGF20H60DF uses the TO-220FP (Type B) package - a full-molded, insulated variant with integral plastic barrier between leads and metal tab, rated for 2.5 kV RMS insulation withstand voltage. The metal tab serves as the collector terminal and must be electrically isolated from heatsink unless system grounding scheme permits direct connection.

FAQ

What is the maximum gate-emitter voltage rating for STGF20H60DF?

The absolute maximum V_GE is ±20 V, as specified in Table 1 of DS9293 Rev 6. Exceeding this rating risks permanent gate oxide damage. Recommended operating range is –10 V to +15 V, with –5 V to –10 V used for reliable turn-off margin against Miller-induced false triggering in high-dV/dt environments.

Does STGF20H60DF require a negative gate drive voltage for reliable turn-off?

No - the device is fully functional with 0 V to +15 V gate drive, but a negative turn-off voltage (–5 V to –10 V) is strongly recommended in high-frequency, high-dV/dt applications like PFC to suppress Miller-induced turn-on. Its V_GE(th) of 5.0–7.0 V provides sufficient noise margin at 0 V gate potential under static conditions.

Can STGF20H60DF be safely paralleled with other IGBTs in the same family?

Yes - ST explicitly qualifies STGF20H60DF for safe paralleling due to its slightly positive V_CE(sat) temperature coefficient and tight parameter distribution (<5% variation in V_CE(sat) and switching times). No emitter degeneration resistors are needed, though matched gate drive impedance and symmetrical PCB layout remain essential.

What is the thermal resistance from junction to ambient (R_thJA) for STGF20H60DF?

R_thJA is not specified for the TO-220FP package because it is highly dependent on heatsink design, mounting pressure, and thermal interface material. Only R_thJC = 4 °C/W (IGBT) and 5.6 °C/W (diode) are guaranteed. Ambient thermal performance must be validated per application using JEDEC JESD51-2 compliant test boards or system-level thermal modeling.
