STMicroelectronics STGWA20M65DF2

Overview

STGWA20M65DF2 from STMicroelectronics is a 650 V, 20 A trench-gate field-stop IGBT with integrated soft-fast antiparallel diode in TO-247 long leads package. It delivers V_CE(sat) = 1.55 V (typ.) at I_C = 20 A and T_J = 25 °C, 10 µs short-circuit withstand time at V_GE = 15 V, and R_thJC = 0.9 °C/W for the IGBT section-optimized for motor control inverters requiring robustness and low conduction loss.

For engineers reviewing the STGWA20M65DF2 datasheet, STGWA20M65DF2 pinout, STGWA20M65DF2 application, or STGWA20M65DF2 equivalent, key selection criteria include short-circuit ruggedness, diode reverse recovery performance (t_rr = 166 ns typ. at T_J = 25 °C), thermal resistance, gate charge (Q_g = 63 nC), and junction temperature rating up to 175 °C.

Technical Context

This IGBT employs ST's proprietary trench gate + field-stop structure to simultaneously minimize conduction loss and switching energy while maintaining high short-circuit capability. Its integrated diode features soft recovery with low Q_rr (690 nC typ.) and controlled dI_rr/dt (769 A/µs), reducing voltage overshoot and EMI in hard-switched PFC and inverter legs.

The device operates across –55 °C to 175 °C junction temperature range and supports gate drive voltages up to ±20 V. Its dynamic characteristics-including t_d(on) = 26 ns, t_f = 65 ns, and E_off = 0.56 mJ-are characterized under standardized inductive load conditions (V_CC = 400 V, I_C = 20 A, R_G = 12 Ω) per JEDEC JESD24-10.

Manufacturer

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

This device belongs to ST's M-series IGBT portfolio-engineered specifically for medium-power inverters where balanced efficiency, ruggedness, and integration (integrated diode) are prioritized over ultra-high-frequency operation.

FAQ

What is the maximum gate-emitter voltage rating for STGWA20M65DF2?

The absolute maximum gate-emitter voltage is ±20 V, as specified in Table 1 of DS11376 Rev 4. Exceeding this rating risks permanent gate oxide damage. Recommended gate drive is +15 V for turn-on and –5 V to –10 V for turn-off to ensure robust noise immunity and fast fall time.

Does STGWA20M65DF2 have an electrically isolated tab?

Yes-the TO-247 long leads package uses an electrically isolated tab (no internal connection to collector or emitter), confirmed by ST's package drawing (Figure 32) and marking "C(2, TAB)" indicating collector pin 2 and isolated tab. This enables direct heatsink mounting without insulating pads in floating topologies.

How does the integrated diode differ from standard FRDs in terms of recovery behavior?

Unlike standard fast recovery diodes, this diode exhibits soft recovery with controlled dI_rr/dt (769 A/µs typ.) and low Q_rr (690 nC typ.), minimizing voltage overshoot and EMI. Its t_rr increases only moderately with temperature (281 ns at T_J = 175 °C), preserving predictability in high-ambient environments.

Can STGWA20M65DF2 be paralleled with identical units?

Yes-tight parameter distribution (V_GE(th), V_CE(sat), and dynamic timing) and matched thermal resistance support stable current sharing. ST recommends symmetrical PCB layout, individual gate resistors (≤12 Ω), and Kelvin emitter connections to ensure dynamic balance across paralleled devices.
