Product details

Overview

SGP15N120XKSA1 from Infineon is a 1200 V, 15 A NPT-type IGBT in PG-TO-220-3-1 package, optimized for motor controls and industrial inverters. It delivers 1.5 mJ turn-off energy at T_j = 25°C, 10 μs short-circuit withstand time at V_GE = 15 V, and 2.5–3.6 V collector-emitter saturation voltage across –40°C to +150°C junction temperature range.

For engineers reviewing the SGP15N120XKSA1 datasheet, SGP15N120XKSA1 pinout, SGP15N120XKSA1 application, or SGP15N120XKSA1 equivalent, key selection criteria include its NPT architecture enabling parallel switching, tight parameter distribution, and JEDEC J-STD-020 qualification for rugged industrial operation under high-voltage transients.

Technical Context

This IGBT employs Non-Punch-Through (NPT) silicon technology, delivering temperature-stable V_CE(sat) and consistent dynamic performance up to 150°C junction temperature. Its 0.63 K/W junction-to-case thermal resistance supports high-power density designs with minimal heatsinking.

The device features integrated gate protection via ±20 V gate-emitter rating and exhibits low reverse transfer capacitance (C_rss ≤ 80 pF), enabling fast, controllable switching in hard-switched topologies with 33 Ω external gate resistor.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	1200 V - Withstands DC bus voltages up to 1200 V in industrial inverters and SMPS.
I_C (DC)	15 A at T_C = 100°C - Sustains continuous motor drive current without derating beyond 100°C case temperature.
E_off	1.5 mJ at T_j = 25°C - Enables high-efficiency 8–20 kHz switching in 3-phase inverter legs with reduced heatsink requirements.
t_SC	10 μs at V_GE = 15 V - Provides deterministic fault response window for overcurrent protection circuitry.
R_thJC	0.63 K/W - Allows direct thermal interface to heatsink with predictable junction temperature rise under 198 W power dissipation.
V_CE(sat)	3.6 V max at T_j = 150°C - Limits conduction loss to ≤54 W at 15 A, critical for thermal stability in sealed enclosures.
C_iss	1500 pF max - Determines gate drive strength requirement: ≥2 A peak current needed for 33 Ω R_G and 24 ns t_d(on).

Pinout & Package

SGP15N120XKSA1 uses the PG-TO-220-3-1 package: insulated plastic case with 3 leads, standard mounting hole, and electrically isolated collector tab. Thermal path is through the collector lead to heatsink.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main high-side power terminal	Electrically isolated metal tab - must be mounted to heatsink with thermal interface material; carries full load current and high dv/dt.
Gate (G)	Control input	High-impedance MOS-controlled terminal requiring <175 nC total charge; sensitive to ESD and ringing - needs local RC snubber and Kelvin connection.
Emitter (E)	Power return and reference node	Low-inductance emitter path (7 nH internal inductance) - critical for stable switching; requires separate Kelvin emitter trace for gate driver feedback.

Key Features

Feature	Design Value
NPT silicon technology	Enables parallel operation without current imbalance due to positive temperature coefficient of V_CE(sat) and tight parameter spread (±5% V_GE(th)).
10 μs short-circuit withstand	Provides deterministic timing margin for hardware-based DESAT detection and gate shutdown before thermal runaway.
JEDEC J-STD-020 qualified	Validated for reflow soldering up to 260°C (10 s), ensuring reliability in automated PCB assembly for industrial control modules.
Pb-free and RoHS compliant	Meets EU Directive 2011/65/EU and IPC-J-STD-609A Class 1, supporting global environmental compliance without performance trade-offs.

IC Role / Device Role / Timing Role: Inverter leg switch managing bidirectional energy flow between rectifier and output transformer.

Use Value: 1.5 mJ E_off enables >96.2% system efficiency at full load; 10 μs t_SC aligns with fast digital protection ASIC response windows.

Solar String Inverters

Induction Heating Systems

Use Scenario: 10 kW string inverter DC-AC stage interfacing PV arrays with grid-tie transformers.

IC Role / Device Role / Timing Role: Main switching element in H-bridge topology, switching at 12–18 kHz with soft-start sequencing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar IGBT switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SGW15N120	Same die, PG-TO-247-3 package with lower R_thJC (0.40 K/W) and higher L_E (13 nH)	Better thermal performance but larger footprint; requires longer gate loop for same EMI control	Select when thermal budget is tighter than board space constraints; verify gate drive loop inductance impact on overshoot.
IXYS IXGN15N120B3	1200 V/15 A, 1.2 mJ E_off, 8 μs t_SC, TO-247 package, no integrated diode	Lower switching loss but reduced short-circuit robustness; requires external freewheeling diode	Prefer for high-frequency SMPS where E_off dominates efficiency; avoid in motor drives requiring intrinsic fault tolerance.

Compared with SGW15N120 and IXGN15N120B3, SGP15N120XKSA1 offers optimal balance of thermal interface simplicity (TO-220 form factor), field-proven short-circuit ruggedness, and JEDEC-compliant manufacturability - making it preferred for cost-sensitive industrial inverters where board-level reliability and assembly yield are prioritized.

FAQ

What is the maximum allowable gate-emitter voltage for SGP15N120XKSA1?

The absolute maximum gate-emitter voltage is ±20 V DC. Operation above +15 V or below –10 V risks permanent gate oxide damage. Recommended gate drive is +15 V for turn-on and –5 V to –10 V for active Miller clamping during turn-off to suppress false triggering.

Does SGP15N120XKSA1 include an integrated freewheeling diode?

No. SGP15N120XKSA1 is a discrete IGBT without an integrated body diode. An external ultrafast recovery diode (e.g., IDH15E120, 1200 V/15 A) must be used in anti-parallel configuration for inductive load commutation.

How does the 10 μs short-circuit withstand time translate to practical protection design?

It defines the maximum safe duration between fault onset and gate shutdown initiation. Protection circuits must detect overcurrent and disable the gate within ≤8 μs to allow 2 μs margin for driver propagation delay and logic latency - typically implemented using DESAT sensing with <1 μs response.

Can SGP15N120XKSA1 be paralleled with other units for higher current capacity?

Yes - its NPT structure provides a positive temperature coefficient for V_CE(sat), enabling stable current sharing. Parallel operation requires matched gate resistors (≤5% tolerance), symmetrical layout, and individual gate drive paths to minimize loop inductance differences.
