Product details
Overview
IPW65R050CFD7AXKSA1 from Infineon is a 650 V, 50 mΩ automotive-qualified Superjunction MOSFET in PG-TO247-3 package with integrated fast body diode, ultra-low Qrr (1.2 µC), RDS(on)×Qg FOM of 5.1 nC·Ω, and 1300 A/µs diF/dt capability-designed for ZVS phase-shift full-bridge and LLC resonant DC-DC stages in on-board battery chargers.
For engineers reviewing the IPW65R050CFD7AXKSA1 datasheet, IPW65R050CFD7AXKSA1 pinout, IPW65R050CFD7AXKSA1 application, or IPW65R050CFD7AXKSA1 equivalent, key selection criteria include avalanche-tested ruggedness (248 mJ EAS), 150 °C max junction temperature, 100% AEC-Q101 qualification, and optimized light-load efficiency via low Eoss (13.0 µJ @ 400 V).
Technical Context
This CoolMOS™ CFD7A device implements a charge-compensated superjunction structure with field-plated gate trench design to achieve simultaneous low RDS(on) (50 mΩ max) and ultra-low Qrr (1.2 µC typ). Its integrated body diode features 1300 A/µs commutation speed and 177 ns trr, enabling reliable zero-voltage switching in hard-commutated PFC and resonant topologies.
The MOSFET delivers 211 A pulsed drain current at TC = 25 °C and maintains stable RDS(on) up to 150 °C (0.092 Ω max), supported by 0.55 °C/W RthJC. Gate drive is optimized for 13 V logic-level control with 5.7 V plateau voltage and 102 nC total gate charge.
Key Specifications

|---|---|
| VDS | 650 V - Withstands DC bus voltages up to 475 V battery systems with margin for transient overvoltage |
| RDS(on),max | 50 mΩ @ 10 V, 25 °C - Enables <1.25 W conduction loss at 50 A continuous drain current |
| Qg,typ | 102 nC - Determines gate driver power requirement and switching transition time under 3.3 Ω RG |
| Eoss @ 400 V | 13.0 µJ - Directly reduces turn-off energy loss in high-frequency resonant converters |
| diF/dt | 1300 A/µs - Supports fast, controlled body diode commutation without oscillation in LLC half-bridge legs |
| trr | 177 ns - Minimizes reverse recovery losses and EMI generation during synchronous rectification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage resonant switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPW65R041CFD7A | 41 mΩ RDS(on), 115 nC Qg, identical 650 V rating and CFD7A die architecture | Higher conduction loss reduction but increased gate drive loss; best for <150 kHz fixed-frequency PFC | Select when lowest possible RDS(on) dominates over switching loss budget in thermally constrained layouts |
| IPP65R045C7 | 45 mΩ RDS(on), 95 nC Qg, non-CFD7A (standard CoolMOS™ C7), no integrated fast diode (trr = 320 ns) | Lacks diF/dt rating and AEC-Q101 validation; unsuitable for automotive ZVS LLC without external diode | Acceptable only for industrial SMPS where cost sensitivity outweighs automotive compliance and resonant performance |
Compared with IPW65R050CFD7AXKSA1, the IPW65R041CFD7A trades higher gate charge for lower conduction loss-ideal for thermally limited PFC-but the IPP65R045C7 lacks critical diode performance and qualification for automotive ZVS operation.

FAQ
Is IPW65R050CFD7AXKSA1 qualified for automotive use?
Yes, it is fully qualified per AEC-Q101 Rev. D, including 100% avalanche testing, HTGB, HTRB, and temperature cycling. It supports automotive on-board charger applications with junction temperature range from –40 °C to +150 °C and meets PPAP requirements when application data is shared early in design.
What is the maximum recommended gate resistor value for ZVS operation?
For reliable ZVS in LLC converters, Infineon recommends RG ≤ 3.3 Ω (as tested in datasheet switching waveforms). Higher values increase turn-on delay and risk incomplete ZVS at light loads; lower values (<2.2 Ω) require careful layout to avoid gate oscillation due to 3.8 Ω intrinsic gate resistance.
Can this MOSFET replace older CFD6 devices in existing designs?
Yes-pin-compatible with IPW65R050CFD6, offering 22% lower Qrr, 15% lower Eoss, and improved diF/dt (1300 A/µs vs. 850 A/µs). Layout changes are not required, but gate drive strength should be verified due to 102 nC Qg (vs. 95 nC for CFD6).
Does the tab require electrical isolation from the heatsink?
No-the tab is internally connected to Drain (Pin 2) and must be electrically tied to the high-voltage DC bus node. Thermal interface material must be electrically insulating (e.g., ceramic-filled silicone pad) if the heatsink is grounded or at a different potential.
