Product details

Overview

IPW95R310PFD7XKSA1 from Infineon Technologies is a 950 V, 310 mΩ superjunction N-channel MOSFET in PG-TO247-3 package with integrated ultra-fast body diode, optimized for LLC and ZVS resonant topologies in industrial SMPS and high-voltage lighting power supplies. It delivers 17.5 A continuous drain current, 61 nC total gate charge, and industry-leading 0.78 µC reverse recovery charge (Qrr) at 400 V.

For engineers reviewing the IPW95R310PFD7XKSA1 datasheet, IPW95R310PFD7XKSA1 pinout, IPW95R310PFD7XKSA1 application, or IPW95R310PFD7XKSA1 equivalent, key selection criteria include hard commutation robustness (diF/dt = 1300 A/µs), low Eoss (4.2 µJ @ 500 V), tight VGS(th) tolerance (±0.5 V), and JEDEC-qualified industrial reliability.

Technical Context

This CoolMOS™ PFD7 device uses charge-compensated superjunction architecture with field-plated gate structure to achieve simultaneous reduction in RDS(on), Qg, Ciss, and Eoss while maintaining 950 V blocking capability. Its integrated fast body diode enables zero-voltage switching without external diode replacement.

The MOSFET features a 3 V nominal gate threshold voltage with ±0.5 V variation across temperature and process, enabling stable turn-on in high-noise industrial environments. Its 1.00 °C/W junction-to-case thermal resistance supports high-power-density designs when mounted on heatsinks with M3/M3.5 screws.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	950 V - Enables direct use in 800 V DC bus systems with 15% safety margin for surge and ripple.
R_DS(on), max	310 mΩ @ T_j = 25°C - Defines conduction loss at rated current; increases to 640 mΩ at 150°C per datasheet.
Q_g, typ	61 nC - Determines gate driver power requirement and switching speed control in resonant converters.
E_oss @ 500 V	4.2 µJ - Quantifies energy lost during turn-off; critical for efficiency in high-frequency LLC operation.
Q_rr	0.78 µC @ V_R = 400 V - Lowest published Qrr in 950 V SJ MOSFET class, reducing diode-related losses in soft-switching.
di_F/dt	1300 A/µs - Confirmed hard commutation robustness for reliable operation in asymmetric half-bridge and phase-shifted full-bridge.
T_j max	150 °C - JEDEC-qualified for continuous industrial operation; enables derating up to 125 °C ambient with proper heatsinking.

Pinout & Package

IPW95R310PFD7XKSA1 is housed in PG-TO247-3 package with isolated tab (Drain-connected), standard lead pitch, and screw-mount compatibility (M3/M3.5). The tab serves as the Drain terminal and provides primary thermal path to heatsink.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Lead)	Gate	Control input; requires <30 V dynamic rating; 1 Ω typical gate resistance limits ringing.
Pin 2 (Tab)	Drain	Main high-voltage power terminal; electrically connected to metal tab for thermal and electrical conduction.
Pin 3 (Lead)	Source	Power return and gate reference node; forms common source path for internal body diode conduction.

Key Features

Feature	Design Value
Integrated ultra-fast body diode	Q_rr = 0.78 µC enables reliable zero-current switching in LLC without external diode snubbing.
Tight V_GS(th) distribution	±0.5 V variation ensures consistent turn-on timing across production lots and temperature range.
Low Eoss × R_DS(on) FoM	Best-in-class figure-of-merit reduces combined conduction and switching losses in 100–500 kHz SMPS.
ESD protection	HBM Class 2 (≥2 kV) minimizes handling damage during PCB assembly and rework.
JEDEC industrial qualification	Validated for 150 °C T_j continuous operation and thermal cycling per JESD22-A104.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage superjunction MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPW95R360PFD7	R_DS(on) = 360 mΩ; 54 nC Q_g; identical 950 V rating and PFD7 body diode	Higher conduction loss but lower gate drive demand; better suited for lower-frequency (<100 kHz) PFC stages	Select when thermal budget allows higher R_DS(on) in exchange for reduced driver complexity.
IPP95R310P7	No integrated fast diode; Q_rr = 2.1 µC; 72 nC Q_g; same R_DS(on) and V_DS	Not suitable for resonant topologies requiring low Q_rr; limited to hard-switched applications	Choose only for cost-sensitive non-resonant SMPS where diode recovery is externally managed.

Compared with IPW95R360PFD7 and IPP95R310P7, IPW95R310PFD7XKSA1 uniquely combines lowest Q_rr, tightest V_GS(th) tolerance, and JEDEC industrial qualification-making it the sole option qualified for high-reliability LLC and ZVS designs above 200 kHz.

FAQ

What is the maximum recommended gate resistor value for reliable ZVS in an LLC half-bridge?

Based on datasheet test conditions (RG = 5.3 Ω, VDD = 400 V, ID = 10.4 A), a gate resistor of 4.7–6.8 Ω is recommended to balance switching speed and ringing suppression. Higher values (>10 Ω) delay turn-on and risk incomplete ZVS at light loads; lower values (<3.3 Ω) increase gate driver stress without measurable efficiency gain.

Does the internal body diode support bidirectional current in synchronous rectification?

No-the internal body diode is unidirectional and optimized for reverse recovery in high-di/dt resonant freewheeling, not synchronous rectification. Its forward voltage is 1.1 V at 10.4 A and 25°C, but it lacks the low V_F and controlled timing required for SR control; external MOSFETs remain necessary for synchronous rectification.

Can IPW95R310PFD7XKSA1 replace older CoolMOS™ P6 devices in existing designs?

Yes, with layout verification: pin-compatible in PG-TO247-3, same 950 V rating and 17.5 A I_D, but lower Q_g (61 nC vs. ~75 nC) and significantly lower Q_rr (0.78 µC vs. >2 µC) require gate driver slew rate adjustment and may reduce snubber losses. Thermal design remains valid due to identical R_thJC = 1.00 °C/W.

Is the tab electrically isolated from the package leads?

No-the metal tab is internally connected to Pin 2 (Drain) and is not electrically isolated. It must be mounted to a heatsink with insulating hardware (e.g., silicone pad + shoulder washer) when the heatsink is at a different potential than the drain node.
