Product details
Overview
STGB3NC120HDT4 from STMicroelectronics is a 7 A, 1200 V very fast IGBT with integrated ultra-fast soft-recovery antiparallel diode in D²PAK (TO-263) package. It delivers low VCE(sat) of 2.3 V at 3 A/25 °C and 2.2 V at 3 A/125 °C, 51 ns reverse recovery time (TJ = 25 °C), and 290 μJ turn-off switching energy - optimized for high-efficiency, medium-power switching in home appliance motor drives and LED lighting ballasts.
For engineers reviewing the STGB3NC120HDT4 datasheet, STGB3NC120HDT4 pinout, STGB3NC120HDT4 application, or STGB3NC120HDT4 equivalent, key selection criteria include its 1200 V blocking capability, thermal resistance of 1.65 °C/W (junction-to-case), soft diode recovery behavior, and compatibility with 15 V gate drive in hard-switched inductive loads.
Technical Context
This IGBT employs ST's PowerMESH process to balance low conduction loss and fast switching performance. Its gate threshold voltage (2–5 V) enables robust noise immunity, while the integrated diode features soft reverse recovery (Qrr = 85 nC, trr = 51 ns) to minimize voltage overshoot and EMI in flyback and half-bridge topologies.
The device operates across –55 to 150 °C junction temperature range and supports ±20 V gate-emitter voltage. With 470 pF input capacitance and 24 nC total gate charge, it achieves 15 ns turn-on delay and 250 ns current fall time under standard 10 Ω gate drive conditions at 800 V DC bus.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCES | 1200 V - supports 800 V DC-link designs with 1.5× safety margin for surge and ringing |
| IC (TC = 100 °C) | 7 A - continuous operation in thermally constrained enclosures without forced cooling |
| VCE(sat) (3 A, 25 °C) | 2.3 V - reduces conduction loss to ~6.9 W at 3 A, enabling >95% efficiency in 1–2 kW inverters |
| trr (di/dt = 100 A/µs) | 51 ns - limits diode reverse recovery dv/dt stress on gate driver and reduces snubber losses |
| RthJC (IGBT) | 1.65 °C/W - allows 75 W power dissipation with ≤125 °C case temperature rise above heatsink |
| Eoff (800 V, 3 A) | 290 μJ - enables <100 kHz switching in PFC and motor control stages with manageable thermal load |
| Qg | 24 nC - compatible with standard 1–2 A peak gate drivers without excessive Miller effect risk |
Pinout & Package
D²PAK (TO-263) package with isolated tab (collector-connected); surface-mount footprint optimized for thermal transfer to PCB copper pour or external heatsink. Tab is electrically connected to collector (pin 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate | Control terminal requiring 15 V nominal drive; 24 nC total charge dictates gate resistor selection for dV/dt control |
| 2 | Emitter | Reference node for gate drive and current sensing; low-inductance layout critical for stable switching |
| 3 / TAB | Collector | Main power output terminal and thermal path; tab must be soldered to large copper area for RthJC = 1.65 °C/W performance |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast soft-recovery diode | Qrr = 85 nC, trr = 51 ns, Irrm = 3.3 A - suppresses voltage spikes and reduces EMI in discontinuous conduction mode |
| Low VCE(sat) at high temperature | 2.2 V @ 3 A / 125 °C - maintains efficiency stability over full operating range without derating |
| PowerMESH trench-gate structure | Enables 470 pF Cies and 6 pF Cres - improves gate controllability and reduces cross-talk susceptibility |
| ECOPACK® compliant packaging | Halogen-free, RoHS-compliant D²PAK - meets global environmental regulations without performance trade-offs |
| High ruggedness rating | ICL = 14 A latching current, RBSOA validated - withstands short-circuit events up to 10 µs at 15 V gate drive |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage IGBT applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STGF3NC120HD | TO-220FP package, higher RthJC = 5 °C/W, same electrical specs | Requires external heatsink mounting; unsuitable for space-constrained SMT layouts | Select when through-hole assembly and mechanical robustness outweigh thermal density needs |
| STGP3NC120HD | TO-220 package, RthJC = 1.65 °C/W (same as D²PAK), but no tape-and-reel option | Limited to manual or pick-and-place with lead-forming; no automated SMT compatibility | Choose for prototyping or low-volume production where D²PAK reflow process is unavailable |
Compared with STGF3NC120HD and STGP3NC120HD, STGB3NC120HDT4 uniquely combines D²PAK's high thermal density (1.65 °C/W) with tape-and-reel SMT manufacturability - making it optimal for high-volume, thermally demanding consumer appliance inverters.

FAQ
What is the maximum gate-emitter voltage rating for STGB3NC120HDT4?
The absolute maximum VGE is ±20 V per datasheet Table 1. Operation beyond ±15 V risks permanent gate oxide damage. Recommended gate drive is 15 V for turn-on and –5 V to 0 V for turn-off to ensure reliable switching and minimize Miller-induced false triggering.
Does STGB3NC120HDT4 require an external freewheeling diode?
No - it integrates a monolithic ultra-fast soft-recovery antiparallel diode with 3 A RMS forward current rating and 12 A non-repetitive surge capability. This eliminates discrete diode count and layout complexity in half-bridge and single-switch topologies.
How does thermal performance differ between D²PAK and TO-220FP versions?
STGB3NC120HDT4 (D²PAK) has RthJC = 1.65 °C/W, while STGF3NC120HD (TO-220FP) is 5 °C/W - a 3× higher thermal resistance. This means the D²PAK version dissipates the same 75 W power with only 124 °C junction-to-case rise versus 375 °C for the TO-220FP, making it essential for compact, convection-cooled designs.
Can STGB3NC120HDT4 be used in short-circuit conditions?
Yes - it is rated for 14 A turn-off latching current (ICL) and validated in RBSOA testing. Under 15 V gate drive and 800 V VCE, it withstands ≥10 µs short-circuit events before desaturation, provided gate drive remains active and heatsink temperature stays below 100 °C.
