Product details
Overview
SGI02N120XKSA1 from Infineon Technologies is a 1200 V, 2 A NPT (Non-Punch-Through) IGBT in PG-TO-262-3-1 (I²-PAK) package, optimized for high-voltage switching in motor controls and SMPS. It delivers 0.11 mJ turn-off energy (Eoff), 10 µs short-circuit withstand time at Tj ≤ 150°C, and VCE(sat) = 3.1 V (typ.) at IC = 2 A, Tj = 25°C.
For engineers reviewing the SGI02N120XKSA1 datasheet, SGI02N120XKSA1 pinout, SGI02N120XKSA1 application, or SGI02N120XKSA1 equivalent, key selection criteria include its NPT-based ruggedness, tight parameter distribution across temperature, parallel-switching capability, and JEDEC1 qualification for industrial inverter use.
Technical Context
This IGBT employs Non-Punch-Through (NPT) technology to achieve high thermal stability and uniform electrical characteristics over -55°C to +150°C junction temperature range. Its design enables reliable operation under repetitive short-circuit stress (≤1000 events, >1 s interval) and supports gate drive with ±20 V VGE rating.
The device features low dynamic losses: Eon = 0.27–0.33 mJ and Eoff = 0.11–0.15 mJ at Tj = 150°C, VCC = 800 V, IC = 2 A, RG = 91 Ω. Input capacitance (Ciss) is 205–250 pF, enabling predictable gate drive sizing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCE | 1200 V - Maximum blocking voltage for 1200 V DC bus applications like industrial inverters and HV SMPS. |
| IC (DC) | 2 A - Continuous collector current rating at TC = 100°C; usable up to 6.2 A pulsed (tp limited by Tjmax). |
| Eoff | 0.11 mJ - Confirmed turn-off energy at Tj = 25°C, VCC = 800 V, IC = 2 A, enabling efficient high-frequency switching. |
| tSC | 10 µs - Short-circuit withstand time at VGE = 15 V, critical for fault-tolerant motor control protection schemes. |
| RthJC | 2.0 K/W - Junction-to-case thermal resistance, supporting 62 W power dissipation at TC = 25°C. |
| VCE(sat) | 3.1 V (typ.) - Low saturation voltage at IC = 2 A, Tj = 25°C, minimizing conduction loss in medium-power stages. |
| Ciss | 205–250 pF - Input capacitance at VCE = 25 V, defining gate drive current requirements and switching speed control. |
Pinout & Package
SGI02N120XKSA1 uses the PG-TO-262-3-1 (I²-PAK) package: insulated plastic case with isolated collector tab, 3-terminal through-hole mounting, and 2.0 K/W thermal resistance from junction to case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main high-side power terminal | Electrically connected to metal tab; requires direct thermal interface to heatsink; rated for 1200 V blocking. |
| Gate (G) | Control input | High-impedance MOS-controlled terminal; ±20 V absolute max rating; 11 nC total gate charge defines drive strength requirement. |
| Emitter (E) | Power return and reference node | Low-inductance emitter path (LE = 7 nH); serves as common reference for gate drive and current sensing in half-bridge configurations. |
Key Features
| Feature | Design Value |
|---|---|
| NPT process technology | Delivers tight parameter distribution and stable VCE(sat) vs. temperature-enables robust parallel operation without current-sharing resistors. |
| 10 µs short-circuit withstand | Allows time for external protection circuitry (e.g., DESAT detection + shutdown) to respond before thermal runaway occurs. |
| JEDEC1 qualification | Validated for reliability in target applications including motor drives and industrial power supplies per JESD22-A108. |
| Pb-free & RoHS compliant | Meets global environmental compliance requirements; lead plating compatible with standard reflow profiles (260°C peak). |
| Low Eoff (0.11 mJ) | Reduces switching loss by ~40% vs. prior generation-directly improves efficiency in 10–100 kHz SMPS and servo drive designs. |
Applications
| Industrial Motor Drives | High-Voltage SMPS |
|---|---|
|
Use Scenario: Three-phase inverter stage in 0.5–2 kW variable-frequency drives for pumps and fans. IC Role / Device Role / Timing Role: High-side switch in 6-pulse IGBT bridge; commutates at 4–16 kHz with controlled dv/dt.

IC Role / Device Role / Timing Role: Hard-switched main power switch; operates at fixed 50–100 kHz with zero-voltage transition assistance. Use Value: 0.11 mJ Eoff reduces total switching loss by ≥35% versus legacy 1200 V IGBTs, improving full-load efficiency by 0.8–1.2%. |
| Solar Inverters | Induction Heating |
|
Use Scenario: DC-link switching stage in string inverters converting 600–1000 V PV array output to grid-synchronized AC. IC Role / Device Role / Timing Role: Unidirectional high-voltage switch in boost or buck-boost converter; handles bidirectional current via external diode. Use Value: NPT ruggedness ensures stable VCE(sat) across wide ambient temperature swings (−25°C to +60°C outdoor enclosures). |
Use Scenario: Resonant half-bridge in 3–10 kW domestic and commercial induction cooktops. IC Role / Device Role / Timing Role: Medium-frequency (20–50 kHz) hard-switched power switch; subjected to high di/dt and voltage transients. Use Value: 2.0 K/W RthJC and 150°C Tjmax allow sustained 2 A conduction with minimal heatsink volume-critical for compact appliance designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STGP20NC120WD | 1200 V, 20 A, TO-247; higher current rating but larger die and 0.22 mJ Eoff at same conditions. | Targeted at higher-power inverters (>5 kW); not drop-in due to different package, pinout, and gate charge (45 nC vs. 11 nC). | Select when scaling to higher load currents; avoid if board space or gate drive capability is constrained. |
| IXYS IXGN20N120B3 | 1200 V, 20 A, TO-247; trench-gate field-stop IGBT with 0.18 mJ Eoff, 15 µs tSC. | Optimized for soft-switching topologies; higher cost and no RoHS-compliant variant in this series. | Prefer for designs requiring longer short-circuit margin; verify compatibility with existing gate driver slew rate limits. |
Compared with STGP20NC120WD and IXGN20N120B3, SGI02N120XKSA1 offers lower gate charge and smaller footprint for space-constrained 2 A applications, while maintaining sufficient ruggedness for industrial motor control-making it optimal where cost, size, and thermal management are tightly coupled.

FAQ
What is the maximum allowable gate-emitter voltage for SGI02N120XKSA1?
The absolute maximum gate-emitter voltage is ±20 V DC, as specified in the "Maximum Ratings" table. Exceeding this rating-even briefly-risks permanent gate oxide damage. Recommended operating VGE is +15 V for turn-on and −5 V to 0 V for turn-off to ensure fast, low-loss switching and noise immunity.
Can SGI02N120XKSA1 be used in parallel configurations?
Yes-its NPT structure provides positive temperature coefficient for VCE(sat), enabling inherent current sharing without external balancing resistors. Thermal coupling between paralleled devices must be matched, and gate drive impedance should be identical to minimize dynamic current imbalance during switching transitions.
Does this IGBT include an integrated freewheeling diode?
No. SGI02N120XKSA1 is a discrete IGBT only. It requires an external ultrafast or soft-recovery freewheeling diode (e.g., IDP20E65D1) in inductive switching applications. The datasheet switching energy values (Eon, Eoff) include diode reverse recovery contribution but assume external diode usage.
What is the thermal resistance from junction to ambient for SGI02N120XKSA1?
Junction-to-ambient thermal resistance (RthJA) is not specified for standalone SGI02N120XKSA1 because it depends entirely on PCB layout and heatsinking. The datasheet provides RthJC = 2.0 K/W (junction-to-case), which is the only thermally guaranteed value. Ambient performance must be validated using measured case temperature and system-level thermal modeling.
