Typical Applications
IKW50N65H5FKSA1 is suitable for 6 applications: Solar String Inverter PFC Boost Stage, Industrial Variable-Frequency Motor Drive, Uninterruptible Power Supply (UPS) Inverter, Induction Heating Resonant Converter, Welding Converter Power Stage, EV Onboard Charger PFC Stage (Industrial/Stationary).
Solar String Inverter PFC Boost Stage
The IKW50N65H5FKSA1 fits solar string inverter PFC boost stages where 650 V VCE rating handles 400 V rectified-mains bus with ample switching-transient margin. Its 50 A continuous current at TC = 100 C supports 10-15 kW single-channel inverters, while the TRENCHSTOP 5 H5 family delivers low VCE(sat) of 1.65 V at 50 A for high-efficiency hard-switched boost operation. The co-packaged anti-parallel diode eliminates the need for an external boost rectifier, reducing BOM cost and PCB area. Engineers typically pair this IGBT with a UCC21750 gate driver and run at 16-32 kHz switching frequency to balance magnetics size against switching loss.
Recommended
Industrial Variable-Frequency Motor Drive
In three-phase 400 V industrial VFDs up to 15 kW, the IKW50N65H5FKSA1 serves as the inverter-leg IGBT with its 650 V VCE providing sufficient headroom above the 565 V DC-bus peak. The 80 A IC at TC = 25 C and 50 A at TC = 100 C support continuous three-phase output without paralleling devices, while the co-packaged diode handles motor-regeneration free-wheeling current. Its 305 W Ptot budget and TO-247 thermal performance simplify heatsink selection, and the 20 V VGE max rating is compatible with standard 15 V gate-drive supplies from drivers like the IR21064STRPBF.
Recommended
Uninterruptible Power Supply (UPS) Inverter
Double-conversion UPS systems in the 5-15 kW range leverage the IKW50N65H5FKSA1 in the inverter bridge that converts the 384 V DC bus to 230 V AC mains output. The 650 V VCE rating derates comfortably to 400 V bus operation, and the 50 A continuous current supports 230 V x 30 A continuous three-phase or single-phase-with-neutral inverter legs. The H5 family tuning reduces switching losses in hard-switched IGBT bridges at the typical 16-20 kHz UPS PWM frequency. The built-in anti-parallel diode simplifies the bridge layout and is qualified for the continuous free-wheeling currents encountered during overload transients.
Recommended
Induction Heating Resonant Converter
Induction-heating cooktops and industrial IH heaters operating at 20-50 kHz benefit from the IKW50N65H5FKSA1's hard-switching-optimized TRENCHSTOP 5 H5 cell design, which minimizes turn-off losses during the resonant-commutation cycles. The 650 V VCE rating fits 400 V rectified-mains designs, and 50 A continuous current supports heating coils in the 5-10 kW range. The TO-247 package's low thermal resistance theta_JC enables compact heatsink integration, while the gate-charge characteristic allows straightforward zero-voltage-switching (ZVS) implementation with appropriately tuned resonant tanks.
Recommended
Welding Converter Power Stage
Welding power sources require rugged switches that handle high peak currents and short-circuit conditions, where the IKW50N65H5FKSA1's 650 V VCE and 50 A continuous rating fit primary-secondary full-bridge and half-bridge topologies. The IGBT's short-circuit withstand time (typically 5-10 us for H5 family) supports the arc-strike and arc-stability transients characteristic of MMA/TIG welding. Its low VCE(sat) of 1.65 V reduces conduction losses during the high-current welding arc, improving efficiency and reducing heatsink requirements in portable inverter welders up to 200 A output.
Recommended
EV Onboard Charger PFC Stage (Industrial/Stationary)
Although not AEC-Q100 qualified, the IKW50N65H5FKSA1's 650 V VCE and 50 A continuous current suit stationary EV charging station AC-DC PFC boost stages at 11-22 kW. The H5 family delivers the hard-switching performance required for totem-pole or bridgeless PFC topologies operating at 50-100 kHz, with the co-packaged diode providing bidirectional current paths in bridgeless designs. Industrial charging cabinets benefit from the TO-247's screw-mount heatsink compatibility and the Infineon H5 family reputation for reliability in continuous-duty power-conversion service.

Key Differentiators
- TRENCHSTOP 5 H5 family - hard-switching optimized (vs IKW50N65ES5XKSA1)
- 50A continuous current at TC=100C - high headroom (vs IXYH40N65C3H1)
- Lower VCE(sat) vs comparable 650V TO-247 IGBTs (vs IRGP6650DPBF)
Design Notes
Estimated: at IC = 50 A, VCE(sat) = 1.65 V, and DC conduction (worst case), the IKW50N65H5FKSA1 dissipates roughly 82.5 W; at 30 A continuous conduction the dissipation is closer to 49.5 W. With theta_JC around 0.49 C/W for TO-247, the junction-to-case temperature rise is approximately 82.5 W x 0.49 C/W = 40 C above case. Always size the heatsink to keep Tj below 150 C derated (175 C absolute max) under worst-case ambient and switching-loss conditions.
The TO-247 metal tab is internally connected to the collector, so the heatsink is at collector potential unless an insulated thermal interface pad (sil-pad or Bergquist) is used. For half-bridge and full-bridge layouts, route the emitter-sense connection back to pin 3 rather than the tab to avoid including tab resistance in the gate-drive return path; this prevents high di/dt induced VGE spikes from causing shoot-through or gate-oxide stress.
Keep the gate-drive loop area as small as possible: place the gate resistor (10-47 ohm) and gate-drive supply decoupling capacitor within 1-2 cm of the gate and emitter pins. The high di/dt during turn-on (typically 1000-3000 A/us for H5 family) creates significant L x di/dt voltage transients; minimize parasitic loop inductance in the power-commutation loop (collector-emitter) with wide short PCB traces or bus bars to limit VCE overshoot below the 650 V rating.
Do not exceed VGE = +/-20 V on the gate - apply -5 to -15 V negative gate bias during off-state to prevent parasitic turn-on from Miller current in bridge configurations. Ensure the co-packaged diode's reverse-recovery current rating is not exceeded; verify IGBT turn-on di/dt is limited by gate resistance to stay within the diode's safe operating area (SOA). Last, confirm DC-link voltage stays below 80% of 650 V (520 V) under worst-case transient conditions for reliable long-term operation.
