Product details

Overview

IPA95R310PFD7XKSA1 from Infineon Technologies is a 950 V, 310 mΩ superjunction MOSFET with integrated ultra-fast body diode, optimized for resonant LLC and ZVS topologies in industrial SMPS and high-voltage lighting power supplies. It delivers 8.7 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 IPA95R310PFD7XKSA1 datasheet, IPA95R310PFD7XKSA1 pinout, IPA95R310PFD7XKSA1 application, or IPA95R310PFD7XKSA1 equivalent, key selection criteria include hard commutation robustness (1300 A/µs diF/dt), low Eoss (4.2 µJ @ 500 V), tight VGS(th) tolerance (±0.5 V), and PG-TO220 FP package compatibility with through-hole thermal management.

Technical Context

This CoolMOS™ PFD7 device employs silicon superjunction architecture with charge compensation trenches 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 SiC diodes.

The MOSFET features a 3 V nominal gate threshold voltage with ±0.5 V variation, enabling stable turn-on under wide supply conditions, and supports gate drive with standard 13 V logic-level controllers. Thermal resistance junction-to-case is 4.0 °C/W, confirming suitability for conduction-limited industrial power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	950 V - Enables direct operation from 800 V DC bus without series stacking in industrial PFC+LLC systems.
R_DS(on), max	310 mΩ @ T_j = 25°C - Delivers low conduction loss at full load in 1–3 kW SMPS designs.
Q_g, typ	61 nC - Reduces gate driver power demand and switching loss in high-frequency (>100 kHz) resonant converters.
E_oss @ 500 V	4.2 µJ - Low output energy capacitance minimizes turn-on loss during ZVS transitions.
Q_rr	0.78 µC @ V_R = 400 V - Lowest published Qrr in 950 V SJ MOSFET class, critical for soft-switching reliability.
diF/dt	1300 A/µs - Supports high-speed synchronous rectification and hard commutation without oscillation or failure.
V_GS(th)	3 V ±0.5 V - Ensures consistent turn-on across temperature and process variation, simplifying gate bias design.

Pinout & Package

IPA95R310PFD7XKSA1 uses the PG-TO220 FP (FullPAK) package with isolated drain tab, designed for high-voltage isolation and mechanical mounting via M2.5 screws (50 Ncm torque). The drain is internally connected to the metal tab for optimal thermal path.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	High-impedance control input requiring <5.3 Ω series gate resistor for safe switching; referenced to source.
Pin 2	Drain	Main high-voltage power terminal; electrically connected to isolated metal tab for heatsink mounting and thermal conduction.
Pin 3	Source	Power return node and gate reference; forms common node with internal body diode cathode.

Key Features

Feature	Design Value
Integrated ultra-fast body diode	Q_rr = 0.78 µC enables reliable LLC resonance without external diode snubbing or timing margining.
Low E_oss & C_iss	E_oss = 4.2 µJ and C_iss = 1765 pF reduce turn-on loss and improve ZVS range in high-frequency topologies.
Tight V_GS(th) distribution	±0.5 V variation eliminates need for adaptive gate bias or overdesign in multi-phase or paralleled configurations.
ESD protection	HBM Class 2 (≥2 kV) reduces production yield loss and field failure risk during PCB handling and assembly.
JEDEC industrial qualification	Fully qualified per JEDEC JESD47 for 150 °C T_j operation, supporting long-term reliability in unventilated enclosures.

Applications

Industrial PFC Stage

LLC Resonant Converter

Use Scenario: Active boost PFC front-end operating from 380–800 V DC bus in factory automation power supplies.

IC Role / Device Role / Timing Role: High-side switch in continuous conduction mode (CCM) boost stage, handling 3–5 kW average power.

Use Value: 950 V rating avoids series stacking; low Q_rr prevents diode-induced shoot-through during zero-crossing commutation.

Use Scenario: Primary-side power switch in 1–2 kW server PSU LLC half-bridge with 500–700 kHz switching frequency.

IC Role / Device Role / Timing Role: Resonant switch synchronized to zero-voltage turn-on; body diode conducts freewheeling current during dead time.

Use Value: 1300 A/µs diF/dt ensures clean commutation; 4.2 µJ E_oss extends ZVS range across line/load variations.

ZVS Flyback for Lighting

High-Voltage DC-DC Isolator

Use Scenario: 100–300 W smart LED driver with universal AC input and regulated 48–56 V output.

IC Role / Device Role / Timing Role: Primary switch in quasi-resonant flyback with valley-switching control and 65–130 kHz variable frequency.

Use Value: Integrated fast body diode eliminates need for external HV diode; 310 mΩ R_DS(on) maintains >92% efficiency at full load.

Use Scenario: Isolated 400 V to 24 V DC-DC converter in EV charging station auxiliary power unit (APU).

IC Role / Device Role / Timing Role: Primary-side switch in phase-shifted full-bridge topology with 100–200 kHz fixed frequency and adaptive dead-time control.

Use Value: 2500 V_rms insulation withstand voltage meets reinforced isolation requirements; 4.0 °C/W R_thJC enables compact heatsink design.

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
IPW95R310CFD7	Same 950 V/310 mΩ rating but in TO-247 package; higher R_thJC (3.5 °C/W) and no integrated fast diode (Q_rr = 1.4 µC).	Lacks integrated diode optimization for LLC; requires external diode snubbing in resonant topologies.	Preferred where higher peak current (12 A) and TO-247 mechanical robustness outweigh diode performance needs.
STW95N95F6	950 V/320 mΩ, Q_rr = 1.1 µC, C_iss = 2100 pF, V_GS(th) = 3.5 V ±1.0 V; PG-TO220FP package.	Higher Q_rr and looser V_GS(th) tolerance reduce ZVS margin and require tighter gate drive tuning.	Valid for cost-sensitive industrial SMPS where 5–10% lower efficiency and reduced soft-switching margin are acceptable.

Compared with IPW95R310CFD7 and STW95N95F6, IPA95R310PFD7XKSA1 provides superior hard commutation robustness (1300 A/µs vs ≤900 A/µs), lowest Q_rr in class, and tightest V_GS(th) control-making it the preferred choice for high-reliability, high-frequency resonant converters demanding minimal design margining.

FAQ

What is the maximum continuous drain current for IPA95R310PFD7XKSA1 at 100°C case temperature?

The maximum continuous drain current is 5.6 A at T_C = 100°C, as specified in Table 2 of the Rev. 2.1 datasheet. This derating reflects thermal limits of the PG-TO220 FP package and ensures safe operation within the 150°C maximum junction temperature rating under sustained load conditions.

Does IPA95R310PFD7XKSA1 require an external gate resistor, and what value is recommended?

Yes, a series gate resistor is required for controlled turn-on/turn-off. The datasheet recommends R_G = 5.3 Ω for characterization (Table 9), yielding 13 ns turn-on delay and 10 ns rise time at V_DD = 400 V. For production designs, 4.7–6.8 Ω balances switching speed, EMI, and gate driver stress.

How does the integrated body diode differ from standard CoolMOS™ P7 devices?

The PFD7 body diode achieves Q_rr = 0.78 µC at 400 V-less than half the 1.6 µC typical of P7-series devices-due to optimized carrier lifetime control and tailored doping profiles. This enables reliable operation in LLC topologies without diode-induced voltage spikes or shoot-through.

Is IPA95R310PFD7XKSA1 suitable for use in high-humidity or outdoor industrial environments?

Yes-the device is fully qualified per JEDEC JESD47 for industrial applications and features 2500 V_rms insulation withstand voltage (1 min, 25°C), confirming robust dielectric integrity. When mounted with conformal coating and proper creepage/clearance layout, it supports IP65-rated enclosure deployments.
