Product details

Overview

IHW15T120FKSA1 from Infineon Technologies is a 1200 V, 15 A TrenchStop® and Fieldstop IGBT with integrated EmCon™ HE anti-parallel diode in PG-TO247-3 package, designed for soft-switching induction heating inverters. It delivers 1.7 V V_CE(sat) at 25°C, 10 µs short-circuit withstand time, and low EMI via soft, fast diode recovery (t_rr = 140 ns at 25°C).

For engineers reviewing the IHW15T120FKSA1 datasheet, IHW15T120FKSA1 pinout, IHW15T120FKSA1 application, or IHW15T120FKSA1 equivalent, key selection criteria include junction-to-case thermal resistance (R_thJC = 1.1 K/W), gate charge (Q_G = 85 nC), diode reverse recovery charge (Q_rr = 950 nC), and temperature-stable V_CE(sat) positive coefficient enabling parallel operation.

Technical Context

This IGBT employs TrenchStop® and Fieldstop technology to achieve tight parameter distribution and ruggedness up to 150°C junction temperature, with a positive temperature coefficient in V_CE(sat) ensuring stable current sharing during parallel switching. Its integrated EmCon™ HE diode features optimized inverse recovery behavior for reduced voltage overshoot and EMI in resonant topologies.

The device is characterized for soft-switching applications where low turn-off energy (E_off = 1.4 mJ at 25°C) and controlled tail current minimize losses, while its 10 µs short-circuit capability supports robust protection in high-power induction heating systems operating at 10–100 kHz switching frequencies.

Use Scenario: High-efficiency LLC and phase-shifted full-bridge converters for EV charging and industrial power supplies.

IC Role / Device Role / Timing Role: Primary-side switch with precise timing control of resonant tank current zero-crossings.

Use Value: 10 µs short-circuit withstand enables fast desat detection and safe shutdown without compromising ZVS margin.

Soft-Switched Motor Drives

High-Power UPS Inverters

Use Scenario: Variable-speed drives for HVAC compressors and pumps using quasi-resonant modulation.

IC Role / Device Role / Timing Role: Upper-leg IGBT in three-phase inverter leg, synchronized with complementary lower-leg switching.

Equivalent & Alternatives

The following parts are listed as comparable options for similar IGBT + anti-parallel diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW15N120T2	Same 1200 V/15 A rating but uses TRENCHSTOP™ 5 technology; V_CE(sat) = 1.65 V (typ), Q_G = 75 nC, t_rr = 120 ns	Lower conduction and switching losses; optimized for higher-frequency PWM (up to 50 kHz) rather than resonant soft-switching	Select when prioritizing efficiency over soft-recovery EMI reduction in hard-switched topologies
FF15R12RT4	1200 V/15 A dual IGBT module with separate diode; V_F = 1.85 V (diode), Q_rr = 1100 nC, R_thJC = 1.3 K/W	Higher diode V_F and Q_rr; designed for modular half-bridge integration with isolated gate terminals	Select when board space constraints favor pre-assembled half-bridge layout and independent gate routing is required

Compared with IKW15N120T2 and FF15R12RT4, IHW15T120FKSA1 offers superior soft-recovery performance (t_rr = 140 ns, Q_rr = 950 nC) and tighter V_CE(sat) distribution-critical for stable parallel operation in high-power induction heating, where EMI and thermal matching dominate design trade-offs.

FAQ

What is the maximum allowable gate-emitter voltage for IHW15T120FKSA1?

The absolute maximum gate-emitter voltage is ±20 V DC, as specified in the Absolute Maximum Ratings table. Operation beyond this range risks permanent gate oxide damage. For reliable switching, gate drive should be limited to +15 V (turn-on) and –5 V to 0 V (turn-off), with transient spikes held below ±20 V by proper PCB layout and gate resistor selection.

Does IHW15T120FKSA1 require an external freewheeling diode?

No. The device integrates a matched EmCon™ HE anti-parallel diode optimized for soft, fast recovery in resonant circuits. This eliminates the need for an external diode in half-bridge or inverter leg configurations, reducing component count and parasitic inductance while maintaining low Q_rr and controlled reverse recovery.

How does the 10 µs short-circuit withstand time translate to system-level protection?

The 10 µs rating assumes V_GE = 15 V, V_CC ≤ 1200 V, and T_j ≤ 150°C. It enables implementation of desaturation detection circuits with <1 µs response time, allowing safe shutdown before thermal runaway. Up to 1000 such events are permitted if spaced >1 s apart, supporting robust fault handling in industrial inverters.

Is IHW15T120FKSA1 RoHS compliant and lead-free?

Yes. The device features Pb-free lead plating and complies with RoHS Directive 2011/65/EU. Its soldering profile is qualified per J-STD-020, supporting peak reflow temperatures of 260°C for 10 seconds at 1.6 mm from the case, making it compatible with standard lead-free assembly processes.
