Product details

Overview

IPA65R310CFDXKSA2 from Infineon Technologies is a 650 V, 11.4 A (T_C = 100 °C), 0.31 Ω R_DS(on) max CoolMOS™ CFD2 superjunction power MOSFET in TO-220 FullPAK package, featuring ultra-fast body diode (t_rr = 95 ns, Q_rr = 0.35 µC), high commutation ruggedness (di/dt = 900 A/µs), and low E_oss (3.5 µJ @ 400 V). It is engineered for resonant-mode SMPS in PC Silverbox, LCD TV, and telecom power supplies.

For engineers reviewing the IPA65R310CFDXKSA2 datasheet, IPA65R310CFDXKSA2 pinout, IPA65R310CFDXKSA2 application, or IPA65R310CFDXKSA2 equivalent, key selection criteria include body diode recovery performance, R_DS(on)×Q_g figure-of-merit (FOM), thermal resistance (R_thJC = 3.9 °C/W), and full-pak package suitability for high-current, low-inductance layouts.

Technical Context

This device implements Infineon's CoolMOS™ CFD2 superjunction architecture with optimized charge balancing for reduced switching and conduction losses. Its gate threshold voltage (V_GS(th) = 3.5–4.5 V) and plateau voltage (6.4 V) support standard 10–15 V gate drivers without level-shifting.

The integrated ultra-fast body diode enables hard- and soft-switching operation in LLC and phase-shifted full-bridge topologies. With 900 A/µs di/dt capability and 50 V/ns dv/dt ruggedness, it withstands fast transient stress during ZVS/ZCS transitions without failure.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	650 V - rated blocking voltage for 400 V DC-link applications with 1.6× safety margin
R_DS(on),max	0.31 Ω @ T_J = 25 °C - enables low conduction loss at 11.4 A continuous drain current
Q_g,typ	41 nC - moderate gate charge supports efficient 100–300 kHz switching with <3.4 Ω gate resistor
E_oss@400V	3.5 µJ - low output energy reduces turn-on loss and eases snubber design in resonant converters
t_rr	95 ns - fast reverse recovery minimizes diode switching loss and ringing in half-bridge configurations
R_thJC	3.9 °C/W - junction-to-case thermal resistance specific to TO-220 FP package, enabling 32 W P_D at T_C = 25 °C
I_D,pulse	34.4 A - peak pulsed current rating supports overload and startup surge handling

Pinout & Package

IPA65R310CFDXKSA2 is housed in a TO-220 FullPAK (PG-TO220FP-3-1) package with isolated drain tab, optimized for high-current PCB mounting and thermal transfer via drain pad soldering.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control input	High-impedance MOS gate requiring <4.5 Ω series resistance to damp oscillation; referenced to source
Pin 2 (Drain)	High-side power terminal	Internally connected to exposed metal tab; must be soldered to large copper area for thermal and electrical integrity
Pin 3 (Source)	Power return / reference node	Low-inductance connection point for gate driver return and current sensing; defines local ground reference

Key Features

Feature	Design Value
Ultra-fast body diode	t_rr = 95 ns, Q_rr = 0.35 µC - eliminates need for external anti-parallel SiC Schottky in many 100–200 kHz resonant designs
High commutation ruggedness	di/dt = 900 A/µs - sustains rapid current reversal under ZVS conditions without latch-up or thermal runaway
Low R_DS(on) × Q_g FOM	12.71 Ω·nC - balances conduction and switching loss for optimal efficiency in 150–300 kHz LLC converters
Industrial-grade qualification	JEDEC J-STD-020 & JESD22 compliant - validated for 150 °C T_J operation and reflow/wave soldering per MSL-1
Pb-free & halogen-free	RoHS-compliant plating and mold compound - meets IPC-1752A material declaration and automotive supply chain requirements

Telecom Rectifier Module

Server PSU Front-End

Use Scenario: Active clamp forward or phase-shifted full-bridge switch in -48 V telecom rectifier delivering 1.5 kW.

IC Role / Device Role / Timing Role: High-reliability power switch subjected to frequent line transients and 150 °C ambient operation.

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
IPW65R310CFD	TO-247 package, R_thJC = 1.2 °C/W, P_D = 104.2 W - higher thermal performance but larger footprint	Better suited for high-power industrial SMPS where heatsink space allows TO-247 mounting	Select when >60 W continuous dissipation is required and board layout accommodates larger package
IPP65R310CFD	TO-220 (non-FullPAK), R_thJC = 1.2 °C/W, drain pin 2 not isolated - lower thermal resistance but no drain-tab soldering	Preferred for cost-sensitive consumer adapters where thermal budget permits leaded mounting only	Choose when PCB cannot support FullPAK drain-pad soldering but still requires low R_thJC

Compared with IPW65R310CFD and IPP65R310CFD, IPA65R310CFDXKSA2 trades some thermal headroom (R_thJC = 3.9 °C/W) for compact size and integrated drain-tab thermal path-ideal for space-constrained, high-density telecom and server power modules.

FAQ

What is the maximum junction temperature for IPA65R310CFDXKSA2?

The absolute maximum junction temperature is 150 °C, as specified in the Infineon datasheet Rev. 2.3. Continuous operation at this temperature requires strict thermal design: R_thJC = 3.9 °C/W and sufficient PCB copper area for the drain tab. Derating begins above 100 °C case temperature per the P_D vs. T_C curve.

Can IPA65R310CFDXKSA2 replace a standard N-channel MOSFET in a hard-switched flyback?

Yes, but with gate drive optimization: its 6.4 V gate plateau and 41 nC total charge require a 10–15 V gate driver with ≤3.4 Ω series resistance. Unlike standard MOSFETs, its ultra-fast body diode eliminates need for external snubbers in discontinuous conduction mode, reducing component count.

Is the drain tab electrically isolated in the TO-220 FullPAK package?

Yes-the TO-220 FullPAK (PG-TO220FP-3-1) package features an electrically isolated drain tab, allowing direct soldering to a thermal pad without shorting to other layers. Pin 2 is internally connected to the tab, while pins 1 and 3 remain insulated; isolation voltage exceeds 2500 V_RMS.

How does IPA65R310CFDXKSA2's body diode performance compare to standard SJ-MOSFETs?

It delivers t_rr = 95 ns and Q_rr = 0.35 µC-up to 3× faster and 5× lower recovered charge than typical 650 V SJ-MOSFETs. This reduces diode switching loss and EMI in bridge configurations, and enables reliable operation at di/dt rates up to 900 A/µs without oscillation or thermal runaway.
