Product details

Overview

IGW08T120FKSA1 from Infineon Technologies is a 1200 V, 8 A low-loss TrenchStop® IGBT with Fieldstop technology, designed for high-reliability switching in frequency converters and uninterruptible power supplies (UPS). It delivers 1.7 V V_CE(sat) at T_j = 25°C, 10 µs short-circuit withstand time at V_GE = 15 V, and operates up to 150°C junction temperature in PG-TO-247-3 package.

For engineers reviewing the IGW08T120FKSA1 datasheet, IGW08T120FKSA1 pinout, IGW08T120FKSA1 application, or IGW08T120FKSA1 equivalent, key selection criteria include its NPT-based positive V_CE(sat) temperature coefficient for stable parallel operation, low gate charge (53 nC), and JEDEC-qualified ruggedness for industrial power conversion designs.

Technical Context

This IGBT employs Non-Punch-Through (NPT) structure with TrenchStop® and Fieldstop technology, enabling tight parameter distribution and temperature-stable V_CE(sat) behavior across -40°C to +150°C. Its positive temperature coefficient ensures current sharing stability during parallel operation without external balancing components.

The device integrates optimized gate geometry for low EMI and fast switching-typical turn-off delay is 450 ns at 25°C and 570 ns at 150°C-with total switching energy of 1.37 mJ (25°C) and 2.28 mJ (150°C) under standard inductive test conditions (V_CC = 600 V, I_C = 8 A, R_G = 81 Ω).

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)	8 A at T_C = 100°C - defines thermal-limited steady-state conduction capability
V_CE(sat)	1.7 V at T_j = 25°C - sets conduction loss baseline; rises to 2.2 V at 150°C for thermal design margining
t_SC	10 µs at V_GE = 15 V - enables robust short-circuit protection timing in UPS/frequency converter fault management
Q_Gate	53 nC - determines gate driver power requirement and influences switching speed vs. EMI trade-off
R_thJC	1.7 K/W - defines thermal path efficiency from junction to case; critical for heatsink sizing
E_off	0.7 mJ at 25°C - quantifies turn-off loss contribution to total system efficiency at nominal load

Pinout & Package

IGW08T120FKSA1 uses the PG-TO-247-3 package: insulated plastic housing with 3 leads, 4.5 mm creepage/clearance, and screw-mount compatible flange for direct heatsink attachment.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main high-side power output terminal	Connected to DC bus or inverter leg high side; carries full load current and withstands full V_CE rating
Gate (G)	Control input for MOS-controlled bipolar conduction	Requires ±20 V absolute max drive; 53 nC total charge defines driver sizing and Miller immunity
Emitter (E)	Power return and reference node for gate drive	Serves as common source for gate loop; internal emitter inductance is 13 nH (measured 5 mm from case)

Key Features

Feature	Design Value
NPT structure with positive V_CE(sat) tempco	Enables inherently stable current sharing in paralleled configurations without external emitter resistors
TrenchStop® + Fieldstop technology	Delivers tight parameter spread (±5% V_CE(sat)) and rugged 10 µs short-circuit capability at 150°C
Low EMI design	Optimized internal layout and capacitance profile (C_iss = 600 pF, C_rss = 28 pF) reduce radiated noise in motor drives
JEDEC J-STD-020 qualified	Validated for reflow soldering up to 260°C (10 s), supporting automated PCB assembly in industrial production
Pb-free / RoHS compliant	Meets EU Directive 2011/65/EU and IPC-J-STD-609A Class 1 requirements for lead-free plating

Renewable Energy Inverters

Industrial Welding Power Supplies

Use Scenario: DC-to-AC conversion in 5–10 kW solar string inverters with transformerless topology.

IC Role / Device Role / Timing Role: Main switching element in H-bridge output stage; operates with unipolar PWM at 12–18 kHz.

Use Value: R_thJC = 1.7 K/W and T_j,max = 150°C support compact heatsinking in outdoor-rated enclosures with natural convection cooling.

Use Scenario: Primary-side switching in resonant DC-DC converters for arc welding equipment (20–40 kHz).

Use Value: Low gate charge (53 nC) and fast fall time (70 ns @ 25°C) minimize switching losses during high-frequency burst-mode operation.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN08N120B3	1200 V / 8 A; higher V_CE(sat) = 2.2 V @ 25°C; lower Q_Gate = 42 nC; TO-247AD package	Larger conduction loss but faster switching; less suited for high-temperature continuous operation	Prefer when minimizing turn-off loss dominates over conduction loss, e.g., high-frequency resonant converters
STMicroelectronics STGW8H120DF2	1200 V / 8 A; V_CE(sat) = 1.85 V @ 25°C; t_SC = 6 µs; integrated fast recovery diode in same package	Shorter short-circuit capability limits fault response window; diode integration reduces board space but increases thermal coupling	Choose when space-constrained single-package half-bridge replacement is required and fault-clearing time <6 µs is acceptable

Compared with IXGN08N120B3 and STGW8H120DF2, IGW08T120FKSA1 offers superior thermal stability (150°C T_j,max with 10 µs t_SC) and tighter V_CE(sat) distribution-critical for multi-module parallel systems in industrial UPS where reliability trumps marginal switching speed gains.

FAQ

What is the maximum gate-emitter voltage rating for safe operation?

The absolute maximum gate-emitter voltage is ±20 V DC. Operation beyond this risks irreversible oxide breakdown in the gate structure. Recommended gate drive is +15 V for turn-on and –15 V for turn-off to ensure robust Miller immunity and fast switching, as validated in the datasheet's dynamic test conditions (R_G = 81 Ω, V_GE = –15/15 V).

Can IGW08T120FKSA1 be used in parallel configurations?

Yes-its Non-Punch-Through (NPT) structure provides a positive temperature coefficient for V_CE(sat), ensuring inherent current sharing stability across temperature and unit-to-unit variation. Parallel operation requires matched gate drive layout, identical heatsinking, and gate resistors within ±5% tolerance to maintain balanced dynamic current distribution.

Is an external freewheeling diode required?

Yes-IGW08T120FKSA1 is a standalone IGBT without an integrated body diode. An ultrafast, soft-recovery freewheeling diode (e.g., IDH08SG120C or equivalent) must be placed anti-parallel to the collector-emitter path to handle inductive load current续流 during turn-off, as confirmed by the inductive-load switching characterization in the datasheet.

What thermal interface material thickness is recommended for optimal R_thJC performance?

For minimum thermal resistance, use a 0.08–0.12 mm bond line thickness of thermally conductive silicone grease (e.g., Dow Corning TC-5623) or phase-change pad (e.g., Henkel Gap Pad VOX 300) between the TO-247 flange and heatsink. Exceeding 0.15 mm adds measurable thermal resistance; below 0.05 mm risks voids and poor contact uniformity per Infineon's mounting guidelines.
