Product details

Overview

IGW15T120FKSA1 from Infineon is a 1200 V, 15 A low-loss NPT IGBT in TrenchStop® and Fieldstop technology, optimized for high-voltage switching in frequency converters and uninterruptible power supplies. It delivers 1.7 V V_CE(sat) at 25°C, 10 µs short-circuit withstand time, and ±20 V gate-emitter voltage rating.

For engineers reviewing the IGW15T120FKSA1 datasheet, IGW15T120FKSA1 pinout, IGW15T120FKSA1 application, or IGW15T120FKSA1 equivalent, key selection criteria include V_CE(sat) temperature stability, gate charge (85 nC), thermal resistance (R_thJC = 1.1 K/W), and safe operating area up to 45 A pulsed current under 1200 V.

Technical Context

This IGBT uses Non-Punch-Through (NPT) structure with TrenchStop® and Fieldstop technology to achieve tight parameter distribution and positive temperature coefficient of V_CE(sat), enabling stable parallel operation. Its 10 µs short-circuit capability and 1.1 K/W junction-to-case thermal resistance support robust operation in high-reliability industrial inverters.

The device features low EMI emissions and low gate charge (85 nC), reducing driver losses and simplifying gate drive design. Switching energy is characterized across temperature (25–150°C), voltage (400–800 V), and gate resistance (5–110 Ω), supporting precise loss modeling in hard-switched topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	1200 V - supports DC bus voltages up to 900 V in three-phase rectified systems with margin
I_C (continuous)	15 A at T_C = 100°C - defines steady-state conduction capability in heatsink-limited designs
V_CE(sat)	1.7 V @ T_j = 25°C - sets conduction loss baseline; rises to 2.2 V @ 150°C with predictable slope
t_SC	10 µs @ V_GE = 15 V - enables reliable desaturation-based short-circuit protection without external crowbar
Q_Gate	85 nC @ V_CC = 960 V - determines gate driver peak current requirement and turn-on/turn-off timing control
R_thJC	1.1 K/W - allows direct thermal interface to heatsink; enables 110 W dissipation at ΔT = 121 K
E_off	2.1 mJ @ T_j = 150°C - quantifies turn-off loss in high-temperature, high-current hard-switching conditions

Pinout & Package

IGW15T120FKSA1 is housed in PG-TO-247-3 package, a through-hole, single-island thermally optimized variant of TO-247 with 3 terminals: Collector (C), Gate (G), and Emitter (E). The case serves as the collector connection, and the package meets RoHS and JEDEC J-STD-020 requirements.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main high-side power terminal	Connected to DC bus or inverter leg high-side; carries full load current and withstands 1200 V blocking
Gate (G)	Control input	Receives ±20 V gate drive signal; 85 nC total charge requires ≥2 A peak driver capability for <100 ns switching
Emitter (E)	Power return and reference node	Serves as source of load current and ground reference for gate drive; internal emitter inductance is 13 nH (measured 5 mm from case)

Key Features

Feature	Design Value
Positive V_CE(sat) tempco	Enables stable current sharing in paralleled IGBTs without external current-balancing resistors
10 µs short-circuit withstand	Allows time for controller-level fault detection and shutdown before thermal runaway occurs
TrenchStop® + Fieldstop architecture	Delivers 1.7 V V_CE(sat) with low tail current, reducing switching losses in 4–20 kHz motor drives
Low EMI signature	Reduces need for snubbers and EMI filter sizing in UPS and solar inverter front-end stages
JEDEC-qualified reliability	Validated per J-STD-020 (reflow) and JESD-022 (storage), supporting industrial 15-year lifecycle deployments

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage IGBT applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN15N120B3	1200 V/15 A, 2.0 V V_CE(sat), 15 µs SCWT, higher Q_G (110 nC)	Higher conduction loss but superior short-circuit ruggedness; suited for infrequent overload scenarios	Prefer when system-level fault clearing >15 µs is guaranteed and gate drive can support higher Q_G
STMicroelectronics STGW15H120DF2	1200 V/15 A, 1.85 V V_CE(sat), 8 µs SCWT, lower R_thJC (0.9 K/W)	Lower thermal resistance improves power density; reduced SCWT limits fault-handling margin	Choose where heatsink space is constrained and short-circuit protection is implemented via fast digital controllers

Compared with IXGN15N120B3 and STGW15H120DF2, IGW15T120FKSA1 offers the lowest V_CE(sat) (1.7 V) and balanced trade-off between short-circuit robustness (10 µs) and thermal performance (1.1 K/W), making it optimal for cost-sensitive, medium-reliability industrial inverters.

FAQ

What is the maximum gate-emitter voltage rating for IGW15T120FKSA1?

The absolute maximum gate-emitter voltage is ±20 V DC. Exceeding this rating risks permanent gate oxide damage. Recommended operating range is –10 V to +15 V for reliable turn-off and noise immunity. Gate drive circuits must limit transient overshoot using clamping diodes or active gate control.

Does IGW15T120FKSA1 include an integrated anti-parallel diode?

No, IGW15T120FKSA1 is a discrete IGBT die in a 3-pin TO-247 package without an integrated freewheeling diode. External ultrafast recovery diodes (e.g., IDH15E120, STTH1512D) must be used in complementary pairs for inductive load commutation.

How does junction temperature affect V_CE(sat) in this IGBT?

V_CE(sat) increases linearly with junction temperature: from 1.7 V at 25°C to 2.2 V at 150°C at I_C = 15 A. This positive temperature coefficient ensures inherent current sharing in paralleled devices and prevents thermal runaway during overload.

Can IGW15T120FKSA1 be operated in parallel configurations?

Yes, its NPT structure provides a positive temperature coefficient of V_CE(sat), enabling stable current sharing without external emitter resistors. Successful parallel operation requires matched gate drive layout, identical PCB trace inductance (<5 nH difference), and thermal coupling via shared heatsink to minimize ΔT_j.
