Product details
Overview
AIMZA75R140M1HXKSA1 from Infineon is a 750 V, 140 mΩ silicon carbide (SiC) MOSFET in PG-TO247-4 package with driver source pin, rated for 38 A peak drain current and qualified to AEC-Q101 for automotive power conversion. It features low RDS(on) × Qfr, high VGS(th) (4.3 V typ), and Crss/Ciss ratio optimized for robust unipolar gate driving in high-voltage on-board chargers and DC-DC converters.
For engineers reviewing the AIMZA75R140M1HXKSA1 datasheet, AIMZA75R140M1HXKSA1 pinout, AIMZA75R140M1HXKSA1 application, or AIMZA75R140M1HXKSA1 equivalent, key selection criteria include avalanche ruggedness (48 mJ), dv/dt immunity (200 V/ns), gate charge (13 nC), thermal resistance (1.74 °C/W), and driver-source pin isolation for reduced common-source inductance in hard-switching half-bridges.
Technical Context
This CoolSiC™ G1-generation SiC MOSFET uses Infineon's proprietary die attach technology and internal body diode for bidirectional operation in HV-LV DC-DC and OBC topologies. Its 750 V blocking capability, 175 °C max junction temperature, and 100% avalanche-tested construction enable reliable operation under harsh automotive transients.
The device integrates a dedicated driver source pin (Pin 3) separate from power source (Pin 2), enabling Kelvin-source gate control to minimize switching losses and suppress parasitic turn-on. Its Crss/Ciss ratio of ~0.7% and high VGS(th) provide inherent noise immunity in high-dv/dt environments typical of 800 V battery systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 750 V - Sustains full 800 V battery system transients with margin; supports 400–800 V EV architectures without derating. |
| RDS(on), typ | 140 mΩ at VGS = 18 V, Tj = 25 °C - Enables <1.2 W conduction loss at 9 A RMS in 11 kW OBC phase-legs. |
| QG, typ | 13 nC - Allows fast 10–20 ns switching with standard 2 A gate drivers; reduces gate drive power in 100–200 kHz soft-switching. |
| Eoss, typ @ 500 V | 5.1 µJ - Low stored output energy minimizes turn-off loss in ZVS resonant converters and improves light-load efficiency. |
| dv/dt ruggedness | 200 V/ns - Withstands rapid voltage transients during commutation in half-bridge configurations without false triggering. |
| Tj,max | 175 °C - Supports compact heatsinking in space-constrained traction auxiliary power modules with >10-year lifetime. |

Pinout & Package
Package: PG-TO247-4 - Thermally enhanced 4-pin TO-247 variant with isolated driver source terminal and tab-connected drain for low-inductance, high-current PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Tab) | Drain | Electrically connected to metal tab; primary high-side current path and thermal interface to heatsink. |
| Pin 2 | Power Source (S) | Main source connection for power current return; carries full load current but not used for gate control. |
| Pin 3 | Driver Source (SDRV) | Kelvin source reference for gate driver IC; eliminates common-source inductance impact on switching waveform fidelity. |
| Pin 4 | Gate | Control input for MOSFET channel; requires 0 V to 18 V logic-level drive; internal RG,int = 16 Ω limits ringing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 750 V SiC MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STW75N140K6-EP | 140 mΩ RDS(on), 15 nC QG, no driver source pin, TO-247-3 package | Lacks Kelvin source; higher gate loop inductance limits >150 kHz hard-switching stability | Preferable for cost-sensitive 100 kHz OBC designs where layout-induced ringing is mitigated via PCB optimization. |
| IXYS IXTH75N140L2 | 140 mΩ RDS(on), 16.5 nC QG, 150 °C Tj,max, TO-247-3 | Lower max junction temperature and no AEC-Q101 qualification; higher Qoss (45 nC) | Suitable for industrial DC-DC where automotive qualification and 175 °C operation are not required. |
Compared with STW75N140K6-EP and IXTH75N140L2, AIMZA75R140M1HXKSA1 delivers superior dv/dt immunity (200 vs. 150 V/ns), lower Eoss (5.1 vs. ≥7.2 µJ), and AEC-Q101 validation-making it the only choice for production automotive OBC and HV-LV DC-DC requiring zero-field failure risk.

FAQ
Can AIMZA75R140M1HXKSA1 be used in parallel configurations?
Yes, but only with matched gate drive loops and symmetrical PCB layout. The device's positive RDS(on) temperature coefficient (1.7× increase from 25 °C to 175 °C) enables natural current sharing. However, the driver source pin must be routed separately for each device to avoid ground bounce coupling; mismatched source inductance causes dynamic current imbalance above 100 kHz.
What is the maximum recommended gate resistor value for hard-switching applications?
For 100–150 kHz hard-switching with 18 V gate drive, Infineon recommends RG ≤ 4.7 Ω to maintain <15 ns rise/fall times while limiting overshoot. At 200 kHz, RG = 2.2 Ω is optimal-verified by measured td(on)/tr of 6/7 ns and td(off)/tf of 13/13 ns with 1.8 Ω external RG in the datasheet test circuit.
Is the internal body diode suitable for continuous freewheeling in bidirectional converters?
Yes-the body diode is fully rated for continuous reverse conduction up to 16 A at TC = 25 °C (11 A at TC = 100 °C), with VSD = 3.9 V typ at 4.7 A and Tj = 25 °C. Its Qfr of 46–57 nC supports efficient zero-current switching in CLLC topologies, but forward recovery time (7–20 ns) requires careful dead-time tuning to avoid shoot-through.
Does the driver source pin require a separate ground plane connection?
Yes-Pin 3 (driver source) must connect directly to the gate driver IC's source reference node via a low-inductance, dedicated trace, physically isolated from the main power source (Pin 2) return path. Sharing ground planes between Pins 2 and 3 defeats the Kelvin sensing benefit and reintroduces 5–15 V gate voltage error during high di/dt events.
