Product details

Overview

IKW25T120FKSA1 from Infineon is a 1200 V, 25 A TrenchStop® and Fieldstop IGBT with integrated soft-fast anti-parallel Emitter Controlled HE diode in PG-TO-247-3 package. It delivers 1.7 V V_CE(sat) at 25 °C and 1.7 V diode forward voltage, enabling high-efficiency 10 µs short-circuit ruggedness in frequency converters and UPS systems.

For engineers reviewing the IKW25T120FKSA1 datasheet, IKW25T120FKSA1 pinout, IKW25T120FKSA1 application, or IKW25T120FKSA1 equivalent, key selection criteria include V_CE(sat) temperature stability, diode reverse recovery charge (Q_rr = 2.3 µC @ 25 °C), gate charge (155 nC), short-circuit withstand time, and thermal resistance (R_thJC = 0.65 K/W).

Technical Context

This IGBT employs non-punch-through (NPT) TrenchStop®/Fieldstop architecture to ensure positive temperature coefficient of V_CE(sat), enabling stable parallel operation and tight parameter distribution across temperature. Its integrated Emitter Controlled HE diode features soft, fast recovery (t_rr = 200 ns @ 25 °C) and low Q_rr, minimizing switching losses and EMI in hard-switched topologies.

The device is qualified per JEDEC J-STD-020/JESD-022 for industrial applications, supports ±20 V gate drive, and exhibits low gate charge (155 nC) and low output capacitance (C_oss = 96 pF), facilitating high-frequency PWM control up to 100 kHz while maintaining thermal robustness (T_j,max = 150 °C).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	1200 V - supports DC bus voltages up to 1000 V in three-phase rectified systems
I_C	25 A continuous - rated for sustained conduction in motor drives and UPS inverters
V_CE(sat)	1.7 V @ T_j = 25 °C - reduces conduction loss by ~1.0 V vs. BUP314D, lowering heatsink requirements
V_F	1.7 V @ T_j = 25 °C - low diode forward drop minimizes anti-parallel path loss during freewheeling
t_SC	10 µs - enables reliable short-circuit protection without desaturation circuit complexity
Q_gate	155 nC - determines gate driver power and switching speed trade-off in 10–50 kHz designs
R_thJC	0.65 K/W - allows 190 W power dissipation at T_C = 25 °C, critical for compact thermal design

Pinout & Package

IKW25T120FKSA1 uses the PG-TO-247-3 package: insulated case, through-hole mounting, 3-terminal configuration with isolated collector tab for direct heatsink attachment and thermal optimization.

Pin/Terminal	Circuit Role	Design Meaning

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
IKW30N120H3	Higher I_C = 30 A, lower V_CE(sat) = 1.6 V @ 25 °C, but higher Q_gate = 190 nC	Better for higher-current, lower-frequency (<10 kHz) motor drives where conduction loss dominates	Select when thermal margin is constrained and gate drive capability supports higher charge
FGA25N120ANTD	Same V_CE = 1200 V, but NPT-only (no Fieldstop), V_CE(sat) = 2.0 V @ 25 °C, no integrated soft diode	Requires external ultrafast diode; suited for cost-sensitive designs with relaxed EMI targets	Choose only if external diode layout and thermal management are fully controlled

Compared with IKW30N120H3 and FGA25N120ANTD, IKW25T120FKSA1 offers optimal balance of conduction efficiency, integrated diode softness, and gate drive simplicity for 25 A industrial inverters operating at 10–50 kHz.

FAQ

What is the maximum allowable gate-emitter voltage for IKW25T120FKSA1?

The absolute maximum gate-emitter voltage is ±20 V DC. Exceeding this risks permanent gate oxide damage. Recommended operating range is –10 V to +15 V for reliable turn-on/turn-off with noise immunity; the internal 8 Ω gate resistor helps dampen ringing but does not replace proper external gate network design.

Does IKW25T120FKSA1 require an external freewheeling diode?

No. It integrates a soft, fast-recovery Emitter Controlled HE diode rated for 25 A continuous and 75 A pulsed current. This diode is co-packaged and thermally coupled to the IGBT die, eliminating need for discrete diodes in standard inverter leg configurations.

How does short-circuit withstand time vary with temperature and bus voltage?

t_SC is specified as 10 µs at V_GE = 15 V, V_CC ≤ 1200 V, and T_j ≤ 150 °C. At elevated T_j or reduced V_GE, t_SC decreases; the device allows <1000 cumulative events with >1 s interval between faults per JEDEC qualification.

Is IKW25T120FKSA1 compatible with standard TO-247 heatsinks?

Yes. The PG-TO-247-3 package uses industry-standard TO-247 mechanical dimensions and mounting hole pattern. Its insulated collector tab allows direct mounting to electrically grounded heatsinks without additional isolation hardware, provided thermal interface material meets R_thJC = 0.65 K/W requirement.
