STMicroelectronics STGP3NB60F

Overview

STGP3NB60F from STMicroelectronics is a 600 V, 3 A N-channel PowerMESH™ IGBT in TO-220 package, optimized for high-frequency switching (<40 kHz) with low V_CE(sat) (1.9 V typ. at 3 A, 25°C), low gate charge (16 nC typ.), and short-circuit rated operation. It serves as a main switch in hard-switched and resonant SMPS and PFC stages.

For engineers reviewing the STGP3NB60F datasheet, STGP3NB60F pinout, STGP3NB60F application, or STGP3NB60F equivalent, key selection criteria include V_CE(sat) at 125°C, total switching loss (326 µJ at T_j = 125°C), thermal resistance (R_thj-case = 1.8 °C/W), and gate drive compatibility with ±20 V rating.

Technical Context

This IGBT employs ST's patented strip layout for enhanced current density and reduced tail current, enabling high-frequency operation while maintaining robust short-circuit withstand capability. Its low input capacitance (C_ies = 230 pF) and fast turn-off (t_d(off) = 230 ns at 125°C) support efficient 20–40 kHz PFC designs.

The integrated anti-parallel diode exhibits t_rr = 45 ns and Q_rr = 2.7 nC at 125°C, minimizing commutation losses in bridge configurations. Gate threshold voltage (V_GE(th) = 3–5 V) ensures reliable TTL/CMOS-level drive compatibility without overdrive risk.

Key Specifications

Pinout & Package

FAQ

Is STGP3NB60F suitable for 100 kHz operation?

No. STGP3NB60F is characterized and optimized for operation below 40 kHz, as stated in its "F" suffix designation. At 100 kHz, switching losses (E_ts = 326 µJ at 125°C) would exceed thermal limits even with aggressive heatsinking. For >50 kHz, consider SiC MOSFETs or specialized RF IGBTs.

Does STGP3NB60F require a negative gate voltage for turn-off?

No. The device specifies ±20 V gate-emitter voltage rating but operates reliably with 0 V turn-off. A negative bias (e.g., –5 V) is optional to improve noise immunity in high-dv/dt environments but not required for functional switching or safe operation.

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

The datasheet specifies I_C = 3 A continuous at T_C = 100°C. This is a derated value based on thermal limits-not an absolute maximum. Exceeding 3 A at 100°C case risks exceeding the 150°C maximum junction temperature, especially with R_thj-case = 1.8 °C/W and V_CE(sat) rise at elevated temperature.

Can STGP3NB60F replace STGP3NC60HD in an existing design?

No. STGP3NC60HD is a 600 V, 3 A IGBT with different gate threshold (4–6.5 V), higher V_CE(sat) (2.2 V typ.), and no short-circuit rating. Substitution would degrade switching speed, increase conduction loss, and remove fault protection-requiring full revalidation of gate drive, thermal, and protection circuits.
