Product details
Overview
IMZA65R040M2HXKSA1 from Infineon is a 650 V, 40 mΩ silicon carbide (SiC) MOSFET in PG-TO247-4 package with 4-pin source-sensing configuration. It delivers ultra-low switching losses (Eon = 30 µJ, Eoff = 16 µJ @ 400 V), benchmark gate threshold voltage (VGS(th) = 4.5 V), and robust body diode operation under hard commutation-enabling high-efficiency, high-power-density designs in EV charging infrastructure and solar PV inverters.
For engineers reviewing the IMZA65R040M2HXKSA1 datasheet, IMZA65R040M2HXKSA1 pinout, IMZA65R040M2HXKSA1 application, or IMZA65R040M2HXKSA1 equivalent, key selection criteria include its 4-pin Kelvin source layout for accurate gate drive control, RDS(on) max of 49 mΩ at Tj = 175 °C, 142 A peak drain current, and JEDEC-qualified industrial reliability.
Technical Context
This CoolSiC™ G2 MOSFET employs Infineon's second-generation SiC trench technology with .XT interconnection for optimized thermal resistance (Rth(j–c) = 0.87 °C/W). Its 4-pin TO247 package separates power source (Pin 2) and driver source (Pin 3), eliminating source inductance-induced gate oscillation during fast switching.
The device features a robust internal body diode (VSD = 4.3 V @ 22.9 A, Tj = 25 °C) and high dv/dt ruggedness (200 V/ns), enabling reliable operation in hard-switched topologies without external anti-parallel diodes. Gate drive flexibility includes compatibility with bipolar schemes (VGS(off) = 0 V, VGS(on) = 18 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 650 V - Maximum blocking voltage across drain-source, rated over full junction temperature range (−55 to +175 °C). |
| RDS(on), max | 49 mΩ - Worst-case on-resistance at Tj = 175 °C, VGS = 18 V, defining conduction loss ceiling in thermal design. |
| QG, typ | 28 nC - Total gate charge required for full turn-on, directly impacting gate driver sizing and switching speed control. |
| Eoss @ 400 V | 7.2 µJ - Output energy stored in Coss, critical for calculating turn-off losses in hard-switched converters. |
| ID,pulse | 142 A - Peak pulsed drain current capability at TC = 25 °C, supporting short-duration overload conditions in motor drives. |
| VGS(th) | 4.5 V (typ) - Precise gate threshold voltage enabling stable turn-on margin and immunity to parasitic turn-on at 0 V gate bias. |
| Rth(j–c) | 0.87 °C/W - Junction-to-case thermal resistance, enabling accurate heatsink sizing for continuous 172 W power dissipation at TC = 25 °C. |
Pinout & Package
Package: PG-TO247-4 - 4-pin through-hole package with isolated tab (drain), designed for high-current, high-thermal-load applications. The tab is electrically connected to drain (Pin 1) and serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Tab) | Drain | Main high-side power terminal and primary thermal interface; electrically tied to drain potential and heatsink mounting surface. |
| Pin 2 | Power Source | High-current source connection for main power loop; carries full load current but not used for gate drive reference. |
| Pin 3 | Driver Source | Kelvin sense connection for gate driver return path; eliminates source inductance impact on gate waveform integrity. |
| Pin 4 | Gate | Control input for MOSFET channel; requires low-inductance routing to minimize ringing and ensure clean switching transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low switching losses | Eon + Eoff = 46 µJ @ 400 V, enabling >99% efficiency in 100 kHz+ PFC and DC–DC stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage SiC MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Wolfspeed C3M0040065K | RDS(on),max = 48 mΩ; QG = 32 nC; no Kelvin source pins (3-pin TO247); VGS(th) = 3.2–4.2 V. | Lacks driver-source sensing, limiting gate drive stability in high-dV/dt environments like multi-level inverters. | Select when cost sensitivity outweighs need for ultra-stable gate control; verify layout for gate oscillation mitigation. |
| ROHM SCT3040KL | RDS(on),max = 45 mΩ; QG = 26 nC; 4-pin TO247; VGS(th) = 5.0–6.5 V; lower Eoff (12 µJ) but higher Eon (34 µJ). | Higher VGS(th) improves noise immunity but requires tighter gate drive voltage regulation above 15 V. | Prefer for noise-critical industrial drives where gate drive margin is constrained; confirm 18 V gate supply availability. |
Compared with C3M0040065K and SCT3040KL, IMZA65R040M2HXKSA1 uniquely combines Kelvin source sensing, industry-leading VGS(th) consistency (±0.55 V), and lowest total switching loss (46 µJ), making it optimal for high-reliability, high-frequency PFC and DAB designs where gate control fidelity is non-negotiable.

FAQ
Can IMZA65R040M2HXKSA1 be used with 0 V gate turn-off?
Yes-the device is explicitly characterized for robustness against parasitic turn-on even with 0 V gate turn-off voltage, thanks to its 4.5 V nominal VGS(th) and tight ±0.55 V tolerance. This enables simplified unipolar gate driving without negative voltage rails, reducing driver complexity and cost in high-volume applications.
What is the maximum recommended gate resistor value for this MOSFET?
Based on datasheet test conditions (RG,ext = 1.8 Ω), the maximum recommended external gate resistor is 5.6 Ω to maintain safe dv/dt (≤200 V/ns) and avoid excessive switching losses. Higher values increase turn-on delay and Eon; lower values risk gate ringing and overshoot, especially with poor PCB layout.
Is the internal body diode suitable for continuous freewheeling in a totem-pole PFC?
Yes-the body diode is fully qualified for hard commutation with Qfr = 56–82 nC and tfr = 7.6–12.2 ns, enabling reliable bidirectional conduction in totem-pole PFC without external diodes. However, continuous conduction should remain within IS,DC = 30.6 A (TC = 25 °C) limits to avoid thermal runaway.
How does the .XT interconnection improve thermal performance versus standard TO247 packages?
The .XT interconnection replaces traditional aluminum bond wires with copper clips and solder die attach, reducing thermal resistance by 15% (to 0.87 °C/W) and improving power cycling endurance by 3×. This directly extends lifetime in thermally demanding applications like EV chargers operating at 40–85 °C ambient with 100% duty cycle.
