Product details

Overview

IPQC65R125CFD7AXTMA1 from Infineon is a 650 V, 125 mΩ automotive-qualified Superjunction MOSFET in PG-HDSOP-22 package with Kelvin source configuration, integrated fast body diode (diF/dt = 1300 A/µs), and AEC-Q101 qualification. It delivers ultra-low Qrr (0.52 µC), low R_DS(on)×Q_g and R_DS(on)×E_oss, and is optimized for ZVS phase-shift full-bridge and LLC resonant DC-DC converters in on-board chargers.

For engineers reviewing the IPQC65R125CFD7AXTMA1 datasheet, IPQC65R125CFD7AXTMA1 pinout, IPQC65R125CFD7AXTMA1 application, or IPQC65R125CFD7AXTMA1 equivalent, key selection criteria include its Kelvin-source-controlled switching behavior, 100% avalanche-tested ruggedness, 66 A pulsed drain current, and validated performance at 150 °C junction temperature in high-reliability automotive power stages.

Technical Context

This CoolMOS™ CFD7A device implements a charge-compensated superjunction structure with an integrated fast-recovery body diode and dedicated Kelvin source terminal (Pin 2) for precise gate drive control. Its dv/dt ruggedness (120 V/ns) and reverse diode commutation speed (1300 A/µs) enable stable operation in hard-switched and resonant topologies without external snubbers.

The PG-HDSOP-22 package features a thermally enhanced exposed drain tab (Pins 12–22 + Tab) and separate driver source (Pin 2) and power source (Pins 3–11) terminals to minimize source inductance and suppress oscillation during high-di/dt switching. Gate resistance is specified at 6 Ω (f = 250 kHz, open drain).

Pinout & Package

PG-HDSOP-22 is a surface-mount, thermally enhanced package with an exposed drain tab (Pins 12–22 + metal tab) and dual-source configuration: Driver Source (Pin 2) for gate loop integrity and Power Source (Pins 3–11) for main current return.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Main gate input; requires low-inductance routing to minimize ringing during fast switching
Pin 2	Driver Source (Kelvin)	Reference for gate driver IC feedback; must not be connected to power source or ground plane
Pins 3–11	Power Source	Main source return path for high-current conduction; routed separately from Driver Source
Pins 12–22 + Tab	Drain	Exposed copper drain pad; soldered directly to PCB thermal pad for <0.78 °C/W R_thJC

Key Features

Feature	Design Value
Integrated fast body diode	di_F/dt = 1300 A/µs and t_rr = 105 ns - Eliminates need for external anti-parallel SiC/Si diode in resonant PFC and DC-DC stages
Kelvin source configuration	Dedicated Pin 2 for gate driver reference - Enables accurate V_GS control and suppresses false turn-on during high-di/dt transitions
AEC-Q101 qualified	Validated for automotive-grade reliability including 100% single-pulse avalanche testing (E_AS = 78 mJ) - Meets functional safety requirements for OBC and traction inverters
Low R_DS(on) × Q_g FOM	125 mΩ × 32 nC = 4.0 nC·Ω - Balances conduction and switching losses for >100 kHz operation in compact OBC designs

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
IPW65R125CFD7XKSA1	TO-247-4 package; identical die, no Kelvin source; R_DS(on) = 125 mΩ, Q_g = 32 nC	Lacks dedicated driver source pin; higher source inductance limits high-frequency ZVS performance	Preferred for cost-sensitive industrial PFC where layout-induced ringing is manageable
STW65N65FD2	650 V, 120 mΩ, Q_g = 42 nC, no Kelvin source, no AEC-Q101	Higher Q_g increases gate drive loss; unqualified for automotive use	Suitable for non-automotive server PSUs requiring lower R_DS(on) but tolerating higher switching loss

Compared with IPW65R125CFD7XKSA1 and STW65N65FD2, IPQC65R125CFD7AXTMA1 uniquely combines AEC-Q101 qualification, Kelvin source control, and ultra-low Q_rr-making it the only choice for production automotive OBCs demanding ZVS stability, EMI compliance, and functional safety traceability.

Manufacturer

Infineon Technologies AG is a German semiconductor manufacturer specializing in power semiconductors, microcontrollers, and security solutions, with leadership in automotive and industrial power systems.

FAQ

What is the purpose of the separate Driver Source (Pin 2) and Power Source (Pins 3–11)?

Pin 2 provides a Kelvin connection for the gate driver's source reference, isolating gate loop impedance from high-current source return paths. Pins 3–11 carry bulk source current to minimize voltage spikes during switching. Mixing these connections causes gate overdrive and potential device failure due to elevated V_GS during high-di/dt events.

Can IPQC65R125CFD7AXTMA1 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'" due to unvalidated safe operating area and thermal runaway risk. Linear applications require dedicated devices with SOA characterization and derating guidance.

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 (MSL) 1 specifications, with reflow peak temperature rated at 260 °C. Full compliance documentation-including substance declarations and test reports-is available via Infineon's official product portal.

How does the integrated fast body diode differ from standard CoolMOS™ body diodes?

This CFD7A generation features a modified drift region and optimized doping profile that reduces reverse recovery charge (Q_rr = 0.52 µC) and increases diode commutation speed (di_F/dt = 1300 A/µs). Unlike earlier CoolMOS™ variants, it achieves near-SiC-like diode performance without external diodes, enabling reliable ZVS in LLC and phase-shifted topologies up to 500 kHz.
