IPW60R180P7XKSA1 Overview
A superjunction MOSFET is a power-semiconductor device that uses a deep-pillar charge-balance structure to break the silicon limit of conventional planar MOSFETs, yielding far lower on-state resistance per unit area at high blocking voltages. CoolMOS P7 specifically targets switched-mode power supplies, power-factor correction, and motor drive topologies, sitting in the broader hierarchy of power MOSFET -> discrete semiconductor -> power management device.
Key features include an ultra-low figure-of-merit (RDS(on) x Eoss), a fast body diode with low Qrr, a wide gate-drive compatibility range (10V typical), and an operating junction temperature range of -55C to +150C. The device uses Infineon's 7th-generation superjunction platform, which succeeds the CoolMOS P6 series with a tighter Rdson distribution and lower gate-charge loss.
The TO-247-3 package provides a tab/lead 3-pin configuration (Gate, Drain, Source) with a large metal tab that doubles as the drain connection and a thermal pad, achieving a typical thermal resistance of around 0.83 C/W junction-to-case (per the P7 family datasheet), which simplifies heatsink design in high-current continuous-conduction applications.
Typical applications include solar inverters, telecom and server SMPS power-factor-correction stages, EV on-board chargers, industrial motor drives, welding equipment, and UPS systems. The combination of 600V breakdown and 18A current makes the part especially well-suited to bridgeless PFC, LLC half-bridge primary, and hard-switching flyback converters in the 1-5 kW power range.
When designing with this device, place the gate driver within 2 cm of the gate pin to suppress parasitic turn-on, use a 10-100 kOhm gate-source resistor for safe turn-off, and ensure the heatsink is sized for at least 60% of the 72W rated dissipation to keep Tj well below 125C at full load. Unlike planar MOSFETs, the P7 has a much softer switching trajectory, so RC snubbers are typically unnecessary.

Typical Applications
IPW60R180P7XKSA1 is suitable for 6 applications: Solar Inverter PFC and DC-AC Stages, Telecom and Server SMPS Primary Switch, EV On-Board Charger PFC and DCDC Stages, Industrial Motor Drive Inverter, Uninterruptible Power Supply (UPS) PFC and Inverter, Welding and Plasma-Cutter Power Stage.
Solar Inverter PFC and DC-AC Stages
The IPW60R180P7XKSA1 is well suited to solar inverter front-end power-factor-correction and full-bridge DC-AC stages, where 600V VDS provides comfortable margin for 380-400V DC-link buses. The 180 mOhm RDS(on) keeps conduction losses modest in continuous-conduction-mode PFC, while the fast body diode and low Qrr reduce reverse-recovery stress in hard-switching transitions. The 18A continuous drain current supports 3-5 kW string-inverter designs without paralleling. Compared with planar 600V MOSFETs, the P7 superjunction structure reduces switching loss by roughly 30% per the Infineon family datasheet, helping designers meet EU efficiency regulations such as the 98% European weighted efficiency target for residential PV.
Recommended
Telecom and Server SMPS Primary Switch
In 1-3 kW telecom and server switched-mode power supplies, the IPW60R180P7XKSA1 serves as the primary-side high-voltage switch in PFC boost or LLC half-bridge topologies. The 600V rating safely handles rectified 230V AC mains plus switching transients, while the 72W power dissipation and TO-247-3 package enable straightforward heatsink mounting. The integrated gate resistor simplifies gate-drive design by dampening parasitic ringing without external components, and the 7th-generation P7 platform achieves an excellent RDS(on) x Eoss figure of merit that reduces turn-on loss in high-frequency LLC stages targeting 100-200 kHz operation.
Recommended
EV On-Board Charger PFC and DCDC Stages
The IPW60R180P7XKSA1 is used in 3.6-11 kW electric-vehicle on-board charger power-factor-correction and isolated DCDC primary stages. The 600V breakdown and 18A current rating are well-matched to 400V traction-bus interconnects, while the P7 superjunction structure's low Qrr reduces dead-time losses in bridgeless totem-pole PFC, which is becoming the industry reference topology for OBCs. The TO-247-3 package supports the high continuous-conduction-mode currents typical of totem-pole operation, and the part's industrial-grade qualification matches automotive-tier requirements when paired with appropriate downstream isolation. Designers should target 80 kHz-150 kHz switching frequency to balance magnetics size versus efficiency.
Recommended
Industrial Motor Drive Inverter
Variable-frequency drives and industrial servo inverters in the 1-5 kW power range use the IPW60R180P7XKSA1 as a primary-side rectifier-side switch or auxiliary brake-chopper transistor. The 600V rating tolerates 480V three-phase rectified bus voltages with adequate derating margin, and the 72W dissipation rating combined with the TO-247-3 thermal tab allows sustained operation at high PWM duty cycles. The P7's low gate charge and integrated gate resistor reduce dynamic losses during 4-16 kHz PWM switching typical of IGBT-replacement motor-drive designs, where the superjunction MOSFET offers lower conduction loss than equivalently-rated IGBTs at moderate switching frequencies.
Recommended
Uninterruptible Power Supply (UPS) PFC and Inverter
Online double-conversion UPS systems from 1-10 kVA use the IPW60R180P7XKSA1 in both the boost-PFC front-end and the inverter bridge. The 600V drain-source voltage withstands 220-240V AC rectified buses with full safety margin, and the 18A continuous rating suits single-device-per-switch designs in this power class without paralleling. The P7 platform's excellent body-diode ruggedness supports the dead-time intervals in the inverter bridge without requiring an external anti-parallel diode, and the integrated gate resistor reduces the BOM count versus discrete solutions, which matters for cost-sensitive UPS designs.
Recommended
Welding and Plasma-Cutter Power Stage
Inverter-based welding machines and plasma cutters operating in the 10-30 A output range use the IPW60R180P7XKSA1 in the primary-side full-bridge or half-bridge converter that steps mains voltage down to a high-current, low-voltage output. The 600V breakdown and 18A rating handle the high peak currents of arc-strike transients, and the TO-247-3 package with metal tab supports through-hole mounting on the chassis-attached heatsink common in welding equipment. The P7's low Qrr and soft body-diode reverse-recovery behavior reduce EMI in the harsh electrical environment of arc welding, helping meet industrial EMC standards such as EN 61000-6-2.

Key Differentiators
- CoolMOS P7 7th-generation superjunction platform with low figure-of-merit (vs IPW60R180P6 (CoolMOS P6))
- 180 mOhm balanced choice in 600V P7 family (vs IPW60R099P7 (99 mOhm))
- Through-hole TO-247-3 with mechanical tab thermal path (vs IPB60R280P7ATMA1 (TO-263/D2PAK surface-mount))
Design Notes
At 18 A continuous drain current with RDS(on) of 180 mOhm, full-load conduction loss is approximately 58 W. Estimated: P_cond = I^2 x RDS(on) = 18^2 x 0.180 = 58.3 W, exceeding the 72 W Tc=25C rating headroom once case temperature rises. The TO-247-3 tab should be mounted to a heatsink with thermal interface material achieving junction-to-ambient thermal resistance below 2 C/W to keep Tj below 125C. Use a thermal pad rated for at least 0.5 C/W or apply a thin layer of high-quality thermal compound.
Route the gate drive trace directly from the controller output to pin 1 (Gate) with the source return trace running parallel to minimize gate-source loop inductance. The P7's integrated gate resistor tolerates parasitic inductance of about 20 nH, but exceeding this can cause 5-10V ringing on VGS during fast turn-off. Place a 10 kOhm gate-source pull-down resistor between Gate and Source to keep the part off during MCU startup, and keep the high-voltage drain trace on a separate copper pour from the low-voltage gate loop.
Do not exceed the VGS maximum of +/-20V absolute (data not in provided source - generic Infineon P7 spec). Use a 12V Zener or TVS clamp on the gate if the gate driver is powered from a higher-voltage rail. The P7 has a low threshold voltage of 3.5V typical, so noise on the gate trace can cause unwanted turn-on; a 10-100 kOhm gate-source pull-down is mandatory. Also note the body diode is suitable for hard-switching PFC, but for very high dV/dt applications an external anti-parallel SiC diode may still be preferred.
