Product details

Overview

IKW20N60TAFKSA1 from Infineon is a 600 V, 20 A TRENCHSTOP™ IGBT with integrated fast anti-parallel diode in TO-247 package, optimized for 2–20 kHz hard-switching applications including induction heating, UPS bridge stages, and solar inverter PFC circuits. It delivers 1.5 V typical V_CE(sat), 0.46 mJ typical E_off, and 310 µC typical Q_rr at 25 °C.

For engineers reviewing the IKW20N60TAFKSA1 datasheet, IKW20N60TAFKSA1 pinout, IKW20N60TAFKSA1 application, or IKW20N60TAFKSA1 equivalent, key selection criteria include its 600 V blocking voltage, 20 A rated current at 100 °C, soft-recovery diode for reduced switching losses, and suitability for asymmetrical full-bridge and half-bridge resonant topologies in industrial power conversion.

Technical Context

This device belongs to Infineon's TRENCHSTOP™ generation, featuring trench-gate field-stop IGBT structure with co-packaged ultrafast soft-recovery diode. Its 2–20 kHz operating range targets medium-frequency hard-switched converters where conduction loss minimization and diode commutation robustness are critical.

The integrated diode exhibits 310 µC reverse recovery charge and soft recovery behavior, enabling reduced voltage overshoot and EMI during turn-off of inductive loads. The 1.5 V V_CE(sat) supports high-efficiency operation at rated current under 100 °C junction temperature.

Package	TO-247 - Standard 3-pin through-hole package with high thermal dissipation capability (R_thJC ≈ 0.8 K/W).

Pinout & Package

IKW20N60TAFKSA1 uses the industry-standard TO-247 package with three terminals: Collector (C), Gate (G), and Emitter (E). The package features isolated mounting hole, copper leadframe, and epoxy-molded body rated for 250 °C peak soldering temperature.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	High-side power output node	Connected to DC bus positive; handles full load current and 600 V blocking during off-state.
Gate (G)	Control input terminal	Receives TTL/CMOS-compatible drive signal; requires 15 V ±10 % for full enhancement and low V_CE(sat).
Emitter (E)	Power return and reference node	Serves as common source for gate drive and current sensing; must be low-inductance layout to avoid shoot-through risk.

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW20N60T	Same die, identical electrical specs, same TO-247 package; differs only in part marking and traceability (no 'AFKSA1' suffix).	No functional difference; both qualified for industrial motor control and UPS.	Select IKW20N60T if full Infineon traceability documentation is not required and cost optimization is prioritized.
IKB20N60T	Same IGBT/diode die, but in TO-263 (D²PAK) surface-mount package; R_thJC = 1.2 K/W vs. 0.8 K/W for TO-247.	Preferred for space-constrained PCB layouts; limited to lower power density due to higher thermal resistance.	Choose IKB20N60T only when board-level assembly constraints prohibit through-hole TO-247 mounting and thermal load remains ≤25 W.

Compared with IKW20N60T, IKW20N60TAFKSA1 offers identical performance with enhanced lot-level traceability per Infineon's automotive-grade manufacturing protocol, while IKB20N60T trades thermal performance for SMT compatibility-making IKW20N60TAFKSA1 optimal for high-reliability industrial inverters requiring proven long-term stability.

FAQ

What is the maximum junction temperature rating for IKW20N60TAFKSA1?

The absolute maximum junction temperature is 175 °C, with continuous operation rated up to 150 °C. Derating curves in the official Infineon datasheet specify allowable collector current versus case temperature, confirming 20 A operation at 100 °C case temperature and 15 A at 125 °C case temperature under standard heatsinking conditions.

Does IKW20N60TAFKSA1 include an anti-parallel diode, and what are its key recovery characteristics?

Yes, it integrates an ultrafast soft-recovery diode with 310 µC typical reverse recovery charge (Q_rr) and softness factor (S-factor) >1.2. This diode enables low-voltage-overshoot commutation in inductive circuits and eliminates need for external snubbers in properly designed 2–20 kHz hard-switched topologies.

Can IKW20N60TAFKSA1 replace IKW20N60H3 in existing designs?

No-IKW20N60H3 is a HighSpeed 3-series IGBT with 1.95 V V_CE(sat) and 0.24 mJ E_off, optimized for 18–60 kHz operation. IKW20N60TAFKSA1 has lower V_CE(sat) (1.5 V) but higher E_off (0.46 mJ), making it unsuitable for >20 kHz use. Substitution would increase conduction loss at high current but reduce switching loss only below 15 kHz.

What gate drive voltage is recommended for reliable operation of IKW20N60TAFKSA1?

A gate-emitter voltage of +15 V (±10 %) is required to achieve specified 1.5 V V_CE(sat) and ensure full enhancement. Gate drive must limit peak negative voltage to –5 V during turn-off to prevent latch-up. Recommended gate resistor values range from 10 Ω (for fast switching with controlled overshoot) to 47 Ω (for EMI-sensitive applications).
