Product details
Overview
IPA65R110CFDXKSA1 from Infineon Technologies is a 650 V, 31.2 A (TC = 25°C) superjunction N-channel power MOSFET in the CoolMOS™ CFD2 family, optimized for resonant and soft-switching topologies. It features RDS(on) = 0.11 Ω (max), Qg = 118 nC (typ), Eoss = 9.2 µJ @ 400 V, and an ultra-fast, rugged body diode with trr = 150 ns and di/dt capability of 900 A/µs - deployed in high-efficiency server PSU LLC half-bridges.
For engineers reviewing the IPA65R110CFDXKSA1 datasheet, IPA65R110CFDXKSA1 pinout, IPA65R110CFDXKSA1 application, or IPA65R110CFDXKSA1 equivalent, key selection criteria include body diode commutation ruggedness, low Eoss/Qg figure-of-merit, TO-220 FullPAK thermal performance, and industrial-grade JEDEC qualification for telecom and solar inverters.
Technical Context
This device implements Infineon's second-generation CoolMOS™ superjunction architecture with charge compensation trenches, enabling simultaneous reduction of conduction and switching losses. Its optimized gate charge profile (Qgs = 21 nC, Qgd = 64 nC) supports precise timing control in ZVS/ZCS circuits.
The integrated body diode is engineered for hard commutation: reverse recovery charge Qrr = 0.8 µC, peak Irrm = 8.3 A, and dv/dt ruggedness up to 50 V/ns under asymmetric switching conditions - critical for bidirectional LLC and phase-shifted full-bridge designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 650 V - rated blocking voltage for primary-side switching in 400 V DC bus applications (e.g., telecom rectifiers, solar MPPT stages) |
| RDS(on) | 0.11 Ω (max) @ TJ = 25°C - enables <1.2 W conduction loss at 31.2 A, reducing heatsink requirements in compact PSUs |
| Qg | 118 nC (typ) - determines gate drive power and switching speed; compatible with standard 1–2 A peak gate drivers |
| Eoss | 9.2 µJ @ 400 V - directly reduces turn-on energy loss in resonant converters, improving efficiency above 100 kHz |
| trr | 150 ns - ensures clean zero-current switching transitions without voltage overshoot in LLC tank circuits |
| di/dt rating | 900 A/µs - supports reliable operation during fast current reversal in synchronous rectification and bidirectional converters |
| PD (TC = 25°C) | 34.7 W - junction-to-case thermal resistance RthJC = 3.6 °C/W enables direct mounting on PCB copper without external heatsink in low-power servers |
Pinout & Package
IPA65R110CFDXKSA1 is housed in a TO-220 FullPAK (PG-TO220FP) package with isolated drain tab, optimized for surface-mount assembly and enhanced thermal transfer via PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Gate) | Control input | High-impedance MOSFET gate requiring <20 V drive; internal gate resistor RG = 1.3 Ω limits ringing |
| Pin 2 (Drain) | High-voltage power output | Exposed drain tab electrically connected to pin 2; must be soldered to large copper pour for thermal and EMI performance |
| Pin 3 (Source) | Power return / reference node | Low-inductance source connection critical for gate loop integrity; ties to local ground plane in half-bridge layout |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast body diode | trr = 150 ns, Qrr = 0.8 µC - eliminates need for external SiC Schottky catch diodes in LLC resonant converters |
| High commutation ruggedness | di/dt = 900 A/µs, EAS = 845 mJ - withstands repeated hard-switching events in PFC boost and motor drive freewheeling |
| Low-loss FOM | RDS(on) × Qg = 13.0 Ω·nC - balances conduction and switching loss for optimal efficiency at 200–500 kHz operation |
| Industrial qualification | JEDEC J-STD-020 (MSL 1), JESD22-A108 - supports reflow-compatible manufacturing and 150°C continuous operation in harsh environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPW65R110CFD | Same die, TO-247 package; RthJC = 0.45 °C/W vs. 3.6 °C/W; PD = 277.8 W | Requires bolt-down heatsink; suited for >5 kW industrial SMPS where thermal mass dominates | Select when higher power density and forced-air cooling are available; avoid in space-constrained SMT designs |
| IPP65R110CFD | Same die, TO-220 (non-FullPAK); RthJC = 0.45 °C/W; drain tab not isolated | Needs insulating washer for heatsink mounting; lower creepage vs. FullPAK variant | Choose for cost-sensitive, through-hole assembled telecom PSUs where isolation and SMT compatibility are secondary |
Compared with IPW65R110CFD and IPP65R110CFD, IPA65R110CFDXKSA1 trades absolute power dissipation for PCB-integrated thermal management - delivering 34.7 W capability with no mechanical heatsink, making it optimal for compact, automated SMT production of sub-2 kW power systems.

FAQ
What is the maximum continuous drain current for IPA65R110CFDXKSA1 at 100°C case temperature?
The maximum continuous drain current is 19.7 A at TC = 100°C, derated from 31.2 A at 25°C per the thermal limit defined by RthJC = 3.6 °C/W and maximum junction temperature of 150°C. This value assumes proper PCB copper area (≥6 cm²) and still-air conditions.
Does IPA65R110CFDXKSA1 require a negative gate voltage for reliable turn-off?
No. The device specifies gate-source voltage limits of ±20 V (static) and ±30 V (AC), with a typical threshold voltage VGS(th) of 4.0 V. A 0 V gate drive fully turns off the MOSFET; applying negative voltage is unnecessary and not recommended per the datasheet.
Can IPA65R110CFDXKSA1 replace standard silicon MOSFETs in existing PFC boost designs?
Yes - but gate drive strength and layout must be reviewed. Its 118 nC Qg demands ≥1.5 A peak gate current; parasitic inductance in the gate loop must be minimized to avoid oscillation. Also verify snubber design, as lower Eoss changes turn-on stress profiles.
Is the TO-220 FullPAK package lead-free and RoHS compliant?
Yes. IPA65R110CFDXKSA1 uses Pb-free plating and halogen-free mold compound, meeting RoHS Directive 2011/65/EU and JEDEC J-STD-020 MSL Class 1 reflow requirements - verified in the Rev. 2.6 datasheet, Section 1.1 and Appendix A.
