Product details
Overview
STGF3NC120HD from STMicroelectronics is a 7 A, 1200 V very fast IGBT with integrated ultra-fast soft-recovery antiparallel diode in TO-220FP package. It delivers low VCE(sat) of 2.3 V (typ.) at 3 A and 25 °C, 15 ns turn-on delay, and 51 ns diode reverse recovery time - optimized for high-efficiency, medium-power switching in home appliance motor drives and LED lighting ballasts.
For engineers reviewing the STGF3NC120HD datasheet, STGF3NC120HD pinout, STGF3NC120HD application, or STGF3NC120HD equivalent, this device is selected where low conduction loss, fast switching, and robust diode recovery are required in 800–960 V inductive load circuits with gate drive compatibility to standard ±15 V logic.
Technical Context
This IGBT employs ST's PowerMESH process to balance low on-state voltage drop and high-speed switching. Its gate threshold voltage (2–5 V) enables reliable turn-on with standard CMOS/TTL-compatible drivers, while its 1.65 °C/W junction-to-case thermal resistance supports stable operation up to 150 °C junction temperature under forced-air cooling.
The integrated diode features soft reverse recovery (Qrr = 85 nC, trr = 51 ns at 25 °C) and low forward voltage (1.6 V typ. at 1.5 A), minimizing switching losses and EMI during commutation in half-bridge topologies used in induction cooktops and dimmable LED drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCES | 1200 V - Withstands DC bus voltages up to 960 V in industrial-grade inductive loads with 25% safety margin |
| IC (TC = 100 °C) | 3 A - Sustains continuous 3 A collector current at 100 °C case temperature without derating in TO-220FP package |
| VCE(sat) | 2.3 V (typ.) - Reduces conduction loss to ~6.9 W at 3 A, enabling higher efficiency than comparable 1200 V IGBTs |
| tr / tf | 3.5 ns / 250 ns - Enables <100 kHz switching in resonant and hard-switched converters with controlled di/dt |
| Qrr | 85 nC - Low reverse recovery charge minimizes tail current overlap loss and snubber stress in bridge configurations |
| RthJC (IGBT) | 5 °C/W - Allows 75 W total dissipation at TC = 25 °C; thermal design must account for 5× higher resistance vs. TO-220 variant |
| Eoff | 290 μJ - Measured at VCE = 800 V, IC = 3 A, RG = 10 Ω; defines minimum gate drive strength needed for efficient turn-off |
Pinout & Package
STGF3NC120HD uses the TO-220FP (Full-Pak) package: insulated plastic body with metal tab acting as collector terminal; no electrical isolation between tab and collector. Package height is reduced vs. standard TO-220 for compact board layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control input requiring ≥15 V for full enhancement; gate charge Qg = 24 nC dictates driver peak current capability |
| 2 (C) | Collector (Tab) | Metal tab is electrically connected to collector; requires insulating mounting hardware when heatsink is grounded |
| 3 (E) | Emitter | Reference node for gate drive and current sensing; low-inductance layout critical to suppress voltage spikes during switching |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast soft-recovery diode | 51 ns trr, 85 nC Qrr, and soft recovery waveform reduce EMI and voltage overshoot in bridge-leg commutation |
| Low VCE(sat) at high temperature | 2.2 V (typ.) at 125 °C ensures stable conduction loss across operating range without thermal runaway risk |
| High dV/dt immunity | Rated for 1200 V VCES with 80% clamping limit - supports robust operation in noisy mains-connected systems |
| ECOPACK-compliant packaging | Meets RoHS and halogen-free requirements per ST's ECOPACK2 specification for environmentally regulated markets |
| Optimized for 10 Ω gate resistance | Switching energy values (Eon/Eoff) specified with RG = 10 Ω - establishes reference design point for driver selection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar very fast IGBT with integrated diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STGP3NC120HD | TO-220 package, RthJC = 1.65 °C/W (vs. 5 °C/W), IC = 7 A @ TC = 25 °C | Higher power handling but requires larger heatsink and non-insulated mounting | Select when thermal budget permits lower RthJC and board space allows standard TO-220 footprint |
| STGB3NC120HDT4 | D²PAK (TO-263) package, tape-and-reel, RthJC = 1.65 °C/W, same electrical specs | Suitable for automated SMT assembly; no through-hole mounting required | Select for high-volume PCB production with reflow capability and space-constrained layouts |
Compared with STGP3NC120HD and STGB3NC120HDT4, STGF3NC120HD trades thermal performance for electrical isolation and compact through-hole mounting - ideal for cost-sensitive, medium-volume home appliance designs where heatsink insulation simplifies compliance testing.

FAQ
What is the maximum gate-emitter voltage rating for STGF3NC120HD?
The absolute maximum VGE is ±20 V, with recommended operating range of –10 V to +15 V. Exceeding +15 V risks accelerated gate oxide degradation, while negative bias below –10 V may cause unintended turn-on due to Miller coupling in high-dV/dt environments.
Can STGF3NC120HD replace STGP3NC120HD in an existing TO-220 footprint?
No - STGF3NC120HD uses TO-220FP (full-pack) with shorter lead length, different pin spacing, and insulated tab, whereas STGP3NC120HD uses standard TO-220 with exposed collector tab. Mechanical and thermal interface differences require PCB and heatsink redesign.
Is the integrated diode rated for continuous conduction mode (CCM) operation?
Yes - the antiparallel diode is rated for 3 A RMS forward current at TC = 25 °C and 12 A non-repetitive surge (10 ms sine), supporting CCM operation in PFC and inverter freewheeling paths when heatsink temperature remains ≤85 °C.
What gate resistor value is recommended for optimal switching performance?
A 10 Ω gate resistor is used in all datasheet switching measurements (Eon, Eoff, td(on)). For lower EMI, increase to 15–22 Ω; for faster switching with higher dV/dt risk, reduce to 5–7 Ω - always verify stability with actual gate driver IC output capability and layout parasitics.
