Product details

Overview

IPA95R450PFD7XKSA1 from Infineon Technologies is a 950 V, 450 mΩ superjunction MOSFET with integrated ultra-fast body diode, optimized for LLC and ZVS resonant topologies in industrial SMPS and lighting applications. It delivers 7.2 A continuous drain current, 43 nC total gate charge, and industry-leading 0.72 µC reverse recovery charge (Qrr) at 400 V.

For engineers reviewing the IPA95R450PFD7XKSA1 datasheet, IPA95R450PFD7XKSA1 pinout, IPA95R450PFD7XKSA1 application, or IPA95R450PFD7XKSA1 equivalent, key selection criteria include hard commutation robustness (1300 A/µs diF/dt), low Eoss (3.0 µJ @ 500 V), tight VGS(th) tolerance (±0.5 V), and PG-TO220 FP package thermal resistance (RthJC = 4.1 °C/W).

Technical Context

This CoolMOS™ PFD7 device uses silicon superjunction technology with charge compensation to achieve high voltage blocking (950 V) while minimizing RDS(on) × Qg and RDS(on) × Eoss figures of merit. Its integrated fast body diode enables reliable zero-voltage switching without external diode supplementation.

The MOSFET features a 3 V gate threshold voltage with ±0.5 V variation, enabling stable turn-on across temperature and process corners, and supports 120 V/ns dv/dt ruggedness-critical for high-frequency resonant converters operating with elevated bus voltages up to 760 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	950 V - Enables operation in 800 V DC-link industrial SMPS and PFC stages with safety margin.
R_DS(on), max	450 mΩ @ T_j = 25°C - Defines conduction loss at rated current; increases to 930 mΩ at 150°C.
Q_g, typ	43 nC - Determines gate drive power and switching speed; low value reduces driver stress.
Q_rr	0.72 µC @ V_R = 400 V - Minimizes diode recovery losses and EMI in LLC/ZVS circuits.
E_oss	3.0 µJ @ 500 V - Directly impacts turn-off energy loss and snubber design requirements.
diF/dt	1300 A/µs - Supports robust hard commutation in asymmetric half-bridge and phase-shifted topologies.
R_thJC	4.10 °C/W - Enables 30 W power dissipation at T_C = 25°C; critical for heatsink sizing.

Pinout & Package

IPA95R450PFD7XKSA1 is housed in PG-TO220 FP (FullPAK) package with isolated drain tab, optimized for high-voltage isolation and thermal performance. The package features solderable leads and 2500 V_rms insulation withstand voltage.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives 10 V gate drive; 3 V V_GS(th) ensures compatibility with standard 5 V/15 V controllers.
Pin 2 (Drain)	High-side power node	Connected to DC bus; electrically isolated tab allows direct heatsink mounting without insulator.
Pin 3 (Source)	Reference node	Serves as return path for load current and gate drive loop; defines local ground reference.

Key Features

Feature	Design Value
Integrated ultra-fast body diode	Enables self-commutated resonant operation in LLC without external diode, reducing BOM count and layout area.
Lowest Q_rr in 950 V class (0.72 µC)	Reduces switching loss and EMI during diode reverse recovery, improving full-load efficiency by ~0.3–0.5% in 100–300 kHz LLC designs.
Tight V_GS(th) tolerance (±0.5 V)	Ensures consistent turn-on timing across units and temperature, simplifying gate drive design and improving system reliability.
ESD protection ≥ Class 2 (HBM)	Reduces production yield loss during PCB assembly and handling; eliminates need for external ESD safeguards.
Optimized FOM: R_DS(on) × E_oss	Delivers best-in-class trade-off between conduction and switching loss for 70–300 kHz industrial SMPS.

Applications

Industrial LLC Resonant Converter

LED Driver with Active PFC + LLC

Use Scenario: 1–3 kW industrial power supply using asymmetric half-bridge LLC topology with 700–800 V DC bus.

IC Role / Device Role / Timing Role: Primary-side high-side switch in resonant tank; handles ZVS turn-on and hard commutation at turn-off.

Use Value: 1300 A/µs diF/dt rating prevents diode-induced shoot-through; low Q_rr cuts recovery loss by >40% vs. P7 series.

Use Scenario: Outdoor LED streetlight driver with universal AC input, active PFC front-end, and isolated LLC stage.

IC Role / Device Role / Timing Role: Main switch in LLC half-bridge; operates at 200–250 kHz with variable frequency control.

Use Value: Integrated fast body diode eliminates need for discrete antiparallel SiC Schottky, reducing cost and board space by 12 mm².

Server PSU with High-Voltage Bus

Industrial Motor Drive Inverter Stage

Use Scenario: 2 kW server power supply with 540 V nominal bus, upgraded to 760 V for higher efficiency and power density.

IC Role / Device Role / Timing Role: High-side switch in phase-shifted full-bridge; subjected to 120 V/ns dv/dt during commutation.

Use Value: 120 V/ns dv/dt ruggedness prevents spurious turn-on; 950 V rating provides 50% overvoltage margin at 760 V bus.

Use Scenario: 3-phase 400 VAC motor drive with 3-level NPC inverter architecture requiring high-voltage clamping capability.

IC Role / Device Role / Timing Role: Clamping switch in flying-capacitor cell; conducts during regeneration and absorbs transient energy.

Use Value: 29 mJ single-pulse avalanche energy (E_AS) enables safe operation during short-circuit events without external snubbers.

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
IPA95R500P7XKSA1	Same 950 V rating but higher R_DS(on) (500 mΩ), no integrated fast diode, Q_rr = 1.4 µC	Limited to hard-switched PFC; unsuitable for LLC due to slow body diode	Select only if cost sensitivity outweighs efficiency targets and topology is non-resonant.
IPW95R600P7FKSA1	TO-247 package, 600 mΩ R_DS(on), same P7 generation, no fast diode, higher R_thJC (0.55 °C/W)	Better thermal headroom but larger footprint; requires external diode for resonant use	Prefer when board space allows TO-247 and legacy P7 qualification is required.

Compared with IPA95R500P7XKSA1 and IPW95R600P7FKSA1, IPA95R450PFD7XKSA1 delivers superior efficiency in resonant topologies via its integrated fast diode and lower Q_rr, while maintaining identical 950 V rating and JEDEC industrial qualification-making it the optimal choice for new LLC-based designs targeting >96% efficiency.

FAQ

What is the maximum continuous drain current for IPA95R450PFD7XKSA1 at 100°C case temperature?

The maximum continuous drain current is 4.5 A at T_C = 100°C, derated from 7.2 A at 25°C per the datasheet's thermal limits. This reflects junction temperature constraints and R_DS(on) increase with temperature, not package current-carrying capacity alone.

Does IPA95R450PFD7XKSA1 require an external freewheeling diode in LLC applications?

No. The device integrates an ultra-fast body diode with 1300 A/µs diF/dt and 0.72 µC Q_rr, validated for self-commutated operation in LLC and ZVS topologies. External diodes are unnecessary unless specific layout or reliability redundancy is mandated.

What is the gate plateau voltage and why does it matter for drive circuit design?

The gate plateau voltage is 4.5 V (typical), measured during Miller region transition. It determines the minimum gate drive voltage needed to sustain full enhancement and influences gate resistor selection to balance switching speed and ringing-especially critical in high-dv/dt resonant circuits.

Is IPA95R450PFD7XKSA1 qualified for automotive applications?

No. It is fully qualified per JEDEC standards for industrial applications only (T_j = –55 to 150°C, AEC-Q101 not claimed). Automotive-grade equivalents require separate qualification, including HTOL, ESD, and temperature cycling tests beyond industrial scope.
