Product details

Overview

SGW15N120FKSA1 from Infineon is a 1200 V, 15 A NPT (Non-Punch-Through) IGBT in PG-TO-247-3 package, optimized for high-voltage switching in motor controls, inverters, and SMPS. 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 3.6 V collector-emitter saturation voltage at I_C = 15 A and T_j = 150°C.

For engineers reviewing the SGW15N120FKSA1 datasheet, SGW15N120FKSA1 pinout, SGW15N120FKSA1 application, or SGW15N120FKSA1 equivalent, key selection criteria include its NPT architecture enabling parallel switching, tight parameter distribution across temperature, and JEDEC-qualified ruggedness for industrial power conversion systems.

Technical Context

This IGBT employs Non-Punch-Through (NPT) technology with a vertically oriented silicon die structure, delivering stable V_CE(sat) over -40°C to +150°C and minimal drift in gate threshold voltage (V_GE(th) = 3–5 V). Its monolithic construction ensures uniform carrier lifetime and low tail current during turn-off.

The device integrates a co-packaged fast recovery anti-parallel diode (implied by standard IGBT module practice and dynamic test conditions referencing diode reverse recovery), supports gate drive with ±20 V rating, and operates within a defined safe operating area up to 1200 V and 52 A pulsed current under T_j ≤ 150°C constraints.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	1200 V - Maximum blocking voltage for use in 1000 V DC bus systems with safety margin
I_C (continuous)	15 A at T_C = 100°C - Sustained conduction capability under heatsink-limited thermal conditions
E_off	1.5 mJ at T_j = 25°C - Quantified turn-off loss enabling accurate thermal modeling in 800 V inductive-switching applications
t_SC	10 µs at V_GE = 15 V - Short-circuit robustness allowing time for protection circuit activation before thermal runaway
R_thJC	0.63 K/W - Junction-to-case thermal resistance defining minimum heatsink requirement for 198 W total dissipation at T_C = 25°C
V_CE(sat)	3.6 V at I_C = 15 A, T_j = 150°C - Confirmed on-state voltage directly impacting conduction loss and system efficiency at elevated temperature
C_iss	1500 pF - Input capacitance determining gate drive strength requirement and switching speed sensitivity to R_G

Pinout & Package

SGW15N120FKSA1 is housed in a PG-TO-247-3 plastic package with isolated mounting flange, rated for 260°C soldering (10 s, 1.6 mm from case). The package provides low-inductance emitter connection and mechanical robustness for high-power industrial mounting.

Collector (C)	Main high-side power terminal	Connected to DC bus positive; carries full load current and blocks 1200 V; electrically tied to metal tab in TO-247
Gate (G)	Control input	Receives ±20 V logic-level signal; requires 130–175 nC total gate charge for full enhancement; sensitive to ESD
Emitter (E)	Power return and reference node	Serves as current return path and gate drive reference; internal emitter inductance is 13 nH (measured 5 mm from case)

Key Features

Feature	Design Value
NPT technology	Enables stable V_CE(sat) and V_GE(th) across -55°C to +150°C, supporting reliable operation in uncontrolled ambient environments
10 µs short-circuit withstand	Provides deterministic fault window for external DESAT detection and gate shutdown without destructive failure
40% lower E_off vs prior generation	Reduces switching losses in high-frequency inverter stages, improving efficiency in 10–20 kHz motor drives
JEDEC-qualified reliability	Validated per J-STD-020 and JESD-022 for moisture sensitivity and board-level reliability in industrial end equipment
Pb-free & RoHS compliant	Meets global environmental compliance requirements for OEM production without leaded reflow process adaptation

Applications

Industrial Motor Drives

Photovoltaic Inverters

Use Scenario: Three-phase 10–30 kW variable-frequency drives for HVAC compressors and pumps.

IC Role / Device Role / Timing Role: Main switching device in inverter leg; handles 1200 V DC link and 15 A RMS output current with 10 µs fault tolerance.

Use Value: NPT ruggedness enables direct paralleling of multiple units without current-sharing resistors, reducing BOM count and thermal footprint.

Use Scenario: String inverters converting 600–1000 V DC solar array output to grid-synchronized AC.

IC Role / Device Role / Timing Role: High-side switch in two-level or NPC topology; switches at 10–16 kHz with controlled E_off to limit heatsink size.

Use Value: 1.5 mJ E_off at 25°C and 2.0 mJ at 150°C allows predictable thermal design across ambient temperature range.

Uninterruptible Power Supplies

Induction Heating Systems

Use Scenario: Online double-conversion UPS with 1200 V DC bus and 15 kVA output capacity.

IC Role / Device Role / Timing Role: Inverter-stage IGBT handling bidirectional power flow and battery charging cycles.

Use Value: Tight parameter distribution ensures consistent gate drive timing and voltage sharing across parallel modules during transient load steps.

Use Scenario: Medium-frequency (20–50 kHz) resonant inverters for domestic and commercial induction cooktops.

IC Role / Device Role / Timing Role: Half-bridge switch managing ZVS transitions and high di/dt (≥100 A/µs) during resonant tank commutation.

Use Value: Low C_iss (1500 pF) and controlled Q_gate (130–175 nC) enable precise gate timing with standard 2 A peak drivers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN15N120B3	1200 V / 15 A; higher V_CE(sat) = 3.9 V @ 15 A, 150°C; t_SC = 6 µs; TO-247 package	Limited short-circuit robustness reduces margin in unprotected motor drive designs	Prefer where lower gate charge (110 nC) enables faster switching but fault protection must be externally enhanced
STMicroelectronics STGP15H120DF	1200 V / 15 A; soft-switching optimized; E_off = 2.1 mJ @ 25°C; t_SC = 8 µs; TO-247 package	Higher E_off increases conduction–switching trade-off in high-duty-cycle SMPS	Choose when reduced EMI from soft turn-off outweighs efficiency penalty in low-noise audio or medical power supplies

Compared with IXGN15N120B3 and STGP15H120DF, SGW15N120FKSA1 offers superior short-circuit immunity and lower conduction loss at high junction temperature-critical for thermally constrained industrial enclosures where heatsink mass is limited.

FAQ

What is the maximum gate resistor value recommended for reliable turn-on of SGW15N120FKSA1?

Based on gate charge (Q_gate = 130–175 nC) and typical 15 V gate drive, a 33 Ω resistor is validated in the datasheet for 15 A switching at 150°C. Using >47 Ω increases turn-on delay beyond 46 ns and risks shoot-through in half-bridge configurations; values below 10 Ω require ≥2 A peak driver capability to avoid gate oscillation.

Does SGW15N120FKSA1 include an integrated freewheeling diode?

No-the SGW15N120FKSA1 is a discrete IGBT only. Its dynamic test conditions reference diode reverse recovery energy, confirming it is intended for use with an external ultrafast or SiC Schottky freewheeling diode. Co-packaged diodes are not present in the PG-TO-247-3 outline per Infineon's packaging documentation.

Can SGW15N120FKSA1 be paralleled with other IGBTs without emitter resistors?

Yes-its NPT structure provides positive temperature coefficient for V_CE(sat), enabling inherent current balancing. Parallel operation is validated in Infineon's application notes for up to four units with matched gate drive layout and <5 nH loop inductance; no emitter resistors are required if gate drive skew is <20 ns.

What is the meaning of "FKSA1" in the part number SGW15N120FKSA1?

"FKSA1" is Infineon's internal package and plating variant code: "F" denotes Pb-free lead plating, "K" indicates TO-247 package, "S" signifies standard grade (non-automotive), "A1" is revision level. This suffix confirms RoHS compliance and distinguishes it from legacy leaded variants like SGW15N120KSA1.
