STMicroelectronics STGW20NB60KD

Overview

STGW20NB60KD from STMicroelectronics is a 600 V, 20 A N-channel PowerMESH™ IGBT in TO-247 package, optimized for high-frequency motor control with short-circuit withstand capability (10 µs), low V_CE(sat) (2.3 V @ 25°C), and low gate charge (85 nC). It integrates an anti-parallel fast recovery diode and targets UPS inverters, welding equipment, and industrial motor drives.

For engineers reviewing the STGW20NB60KD datasheet, STGW20NB60KD pinout, STGW20NB60KD application, or STGW20NB60KD equivalent, key selection criteria include short-circuit ruggedness, 125°C continuous operation at 25 A, co-pack diode reverse recovery performance (t_rr = 80.5 ns), and thermal resistance (R_thj-case = 0.73 °C/W).

Technical Context

This IGBT employs ST's patented strip layout PowerMESH™ structure to achieve high input impedance, low conduction losses, and latch-up immunity. Its gate threshold voltage (5–7 V) and transconductance (8 S) support stable voltage-driven switching in hard-switched topologies up to several tens of kHz.

The device features integrated short-circuit protection rated for 10 µs at V_CE = 0.5 × BV_CES, T_j = 125°C, and R_G = 10 Ω. Its co-pack diode delivers t_rr = 80.5 ns and Q_rr = 181 nC at 125°C, enabling efficient freewheeling in bridge configurations.

FAQ

What is the maximum continuous collector current at 100°C case temperature?

The STGW20NB60KD supports 25 A continuous collector current at T_C = 100°C, as specified in Table 2 of the official datasheet. This rating assumes proper heatsinking to maintain case temperature at or below 100°C and accounts for thermal derating beyond that point using the 1.2 W/°C factor.

Does STGW20NB60KD include an integrated diode, and what are its key parameters?

Yes, it integrates a fast recovery anti-parallel diode rated for 20 A continuous and 80 A pulsed forward current. Key diode specs include V_F = 1.27 V @ 10 A / 25°C, t_rr = 80.5 ns, Q_rr = 181 nC, and I_RRM = 4.5 A, all measured at 125°C with 100 A/µs di/dt.

Is STGW20NB60KD suitable for zero-voltage switching (ZVS) topologies?

Yes-its co-pack diode's fast reverse recovery (t_rr = 80.5 ns) and low Q_rr (181 nC) enable reliable ZVS in resonant half-bridge inverters. The low tail current and absence of latch-up further support clean commutation at 20–50 kHz frequencies.

What gate resistor value is recommended for short-circuit protection response?

A 10 Ω gate resistor is used in the datasheet's short-circuit test condition (t_scw = 10 µs at V_GE = 15 V). For practical designs, 10–22 Ω balances switching speed and fault response; lower values improve turn-off speed but increase gate drive stress during faults.
