Product details

Overview

IPQC65R040CFD7AXTMA1 from Infineon is a 650 V, 40 mΩ automotive-qualified Superjunction MOSFET in PG-HDSOP-22 package with Kelvin source configuration, integrated fast body diode (diF/dt = 1300 A/µs), and 100% avalanche tested. It delivers ultra-low Qrr (1.30 µC) and best-in-class FOM (R_DS(on) × Q_g = 3.88 Ω·nC), enabling high-efficiency PFC and ZVS phase-shift full-bridge operation in on-board chargers.

For engineers reviewing the IPQC65R040CFD7AXTMA1 datasheet, IPQC65R040CFD7AXTMA1 pinout, IPQC65R040CFD7AXTMA1 application, or IPQC65R040CFD7AXTMA1 equivalent, key selection criteria include its Kelvin-source-controlled switching stability, 211 A pulsed drain current capability, 14.8 µJ E_oss at 400 V, AEC-Q101 qualification, and PG-HDSOP-22 thermal performance (R_thJC = 0.35 °C/W).

Technical Context

This CoolMOS™ CFD7A device uses charge compensation technology to achieve low R_DS(on) while maintaining robust dv/dt ruggedness (120 V/ns) and fast reverse recovery (trr = 180 ns). Its Kelvin source pin (Pin 2) separates driver return path from power source (Pins 3–11), eliminating source inductance effects during high-diF/dt commutation.

The integrated body diode supports resonant topologies without external anti-parallel diodes - critical for LLC and bidirectional DC-DC converters. Gate plateau voltage (5.7 V) and low Q_gd/Q_gs ratio (1.0) ensure predictable turn-on/turn-off timing under varying load conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	650 V - Supports 400 V bus designs with 1.6× safety margin against transient overvoltage in automotive OBCs.
R_DS(on),max	40 mΩ @ T_j = 25°C - Enables <1.0 W conduction loss at 24.8 A, reducing heatsink requirements in compact SMD layouts.
Q_g,typ	97 nC - Low gate drive energy allows use with standard 1–2 A gate drivers without excessive Miller-induced oscillation.
E_oss @ 400 V	14.8 µJ - Minimizes hard-switching losses in PFC boost stages operating above 100 kHz.
diF/dt	1300 A/µs - Enables reliable zero-current switching in LLC half-bridge secondaries without snubber networks.
T_j,max	150 °C - Rated for continuous operation in under-hood environments per AEC-Q101 stress test profile.
R_thJC	0.35 °C/W - Delivers 357 W power dissipation at T_C = 25°C, supporting high-power density OBC modules.

Pinout & Package

PG-HDSOP-22 is a thermally enhanced surface-mount package with exposed metal tab (Drain) and 22-pin layout optimized for high-current automotive power stages. The Kelvin source configuration isolates driver return (Pin 2) from main source (Pins 3–11), suppressing gate ringing during fast diode commutation.

Pin/Terminal	Circuit Role	Design Meaning
Tab & Pins 12–22	Drain	Primary high-side switching node; electrically connected to exposed copper tab for direct PCB thermal coupling.
Pin 1	Gate	Main gate control input; requires low-inductance routing to minimize ringing during 115 ns turn-off delay.
Pin 2	Kelvin Source (Driver Source)	Reference return for gate driver IC; must not be swapped with power source pins to avoid instability.
Pins 3–11	Power Source	Main current return path for 64 A continuous conduction; paralleled to reduce resistive drop and skin effect.

Key Features

Feature	Design Value
Integrated fast body diode	diF/dt = 1300 A/µs and Q_rr = 1.30 µC enable clean zero-current turn-on in LLC resonant converters without external diodes.
Kelvin source configuration	Separate driver return (Pin 2) eliminates source inductance impact on gate control loop, ensuring stable switching up to 500 kHz.
AEC-Q101 qualified	Validated for automotive-grade reliability including HTGB, HTRB, and 100% UIS testing - suitable for production OBC and DC-DC modules.
Ultra-low FOM	R_DS(on) × Q_g = 3.88 Ω·nC and R_DS(on) × E_oss = 0.59 mΩ·mJ enable >98% efficiency in 3.3 kW PFC stages.
Thermally optimized SMD	PG-HDSOP-22 package achieves 0.35 °C/W junction-to-case resistance - 30% lower than comparable TO-220FP devices at same R_DS(on).

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
IPW65R041C7	Same 650 V/41 mΩ rating but THD TO-247 package; no Kelvin source; higher R_thJC (0.45 °C/W); Q_rr = 1.45 µC.	Limited to lower-frequency (<150 kHz) PFC due to slower diode recovery and no Kelvin source for high-diF/dt control.	Select when board space permits through-hole mounting and thermal interface allows higher case temperature rise.
STP65N6F7	650 V/38 mΩ in TO-220FP; no AEC-Q101 qualification; Q_g = 115 nC; E_oss = 22.5 µJ; no integrated fast diode.	Suitable only for industrial non-automotive DC-DC where cosmic radiation immunity and automotive reliability are not required.	Choose for cost-sensitive industrial SMPS where AEC-Q101 compliance and resonant topology support are unnecessary.

Compared with IPW65R041C7 and STP65N6F7, IPQC65R040CFD7AXTMA1 uniquely combines AEC-Q101 qualification, Kelvin source control, lowest Q_rr, and PG-HDSOP-22 thermal performance - making it the only option qualified for production automotive OBCs requiring ZVS and bi-directional operation.

FAQ

Can IPQC65R040CFD7AXTMA1 be used in linear mode operation?

No. Infineon explicitly advises against linear mode operation for this device. The datasheet states "We do not recommend using the CoolMOS mentioned in this datasheet to operate in 'linear mode'" and requires direct technical consultation with Infineon sales if such use is considered. Thermal runaway risk and undefined SOA behavior make it unsuitable for analog amplification or constant-current regulation.

What is the maximum allowable gate resistor value for stable switching?

The recommended gate resistor range is determined by the 3.3 Ω reference test condition in the datasheet's dynamic characteristics table. Using RG > 10 Ω increases turn-off delay (td(off) = 115 ns) and risks incomplete turn-off at high frequencies. For 300 kHz operation, RG ≤ 4.7 Ω is advised to maintain <5% duty cycle error and prevent shoot-through in half-bridge configurations.

Is the PG-HDSOP-22 package lead-free and RoHS compliant?

Yes. The PG-HDSOP-22 package meets RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) with peak reflow temperature of 260 °C. Lead finish is 100% matte tin, and all materials comply with Infineon's green policy and conflict minerals reporting requirements.

How does the Kelvin source pin affect PCB layout requirements?

The Kelvin source (Pin 2) must be routed with minimal inductance directly to the gate driver's ground reference, separate from the high-current power source traces (Pins 3–11). Mixing these paths introduces gate voltage error during diF/dt events, causing erratic turn-on and potential device failure. A dedicated 2 mm wide copper pour with via stitching to inner ground planes is required for Pin 2.
