Product details

Overview

AIMZA75R008M1HXKSA1 from Infineon is a 750 V, 90.3 A (T_C = 25 °C), silicon carbide (SiC) MOSFET in PG-TO247-4 package with typ. R_DS(on) = 7.8 mΩ, Q_G = 178 nC, and E_oss = 63.1 μJ @ 500 V. It features separate driver source pin (Pin 3), avalanche-rated ruggedness, and AEC-Q101 qualification for automotive traction inverters and on-board chargers.

For engineers reviewing the AIMZA75R008M1HXKSA1 datasheet, AIMZA75R008M1HXKSA1 pinout, AIMZA75R008M1HXKSA1 application, or AIMZA75R008M1HXKSA1 equivalent, key selection criteria include its 750 V blocking capability, low R_DS(on) × Q_G figure-of-merit, unipolar gate drive robustness, and integrated body diode performance in hard-switching half-bridges.

Technical Context

This CoolSiC™ G1 device uses Infineon's proprietary SiC die attach and trench-gate MOS structure to achieve high dV/dt immunity (200 V/ns), low C_rss/C_iss ratio, and stable V_GS(th) (3.5–5.6 V) across −55 °C to 175 °C. Its 4-pin TO247 layout isolates driver source (Pin 3) from power source (Pin 2) to suppress common-source inductance effects during fast switching.

The MOSFET delivers 926 mJ single-pulse avalanche energy at I_AS = 34.7 A and supports continuous operation up to T_j = 175 °C with R_th(j–c) = 0.29 °C/W. Gate drive is optimized for 0–18 V turn-on and 0 V turn-off, avoiding negative bias while maintaining immunity to parasitic turn-on.

Key Specifications

Pinout & Package

PG-TO247-4 package with isolated tab (Drain), four leads: Pin 1 = Drain, Pin 2 = Power Source, Pin 3 = Driver Source, Pin 4 = Gate. The driver source pin enables Kelvin connection for precise gate voltage control and minimizes dynamic R_DS(on) rise due to source inductance.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Tab)	Drain	Main high-side power terminal; electrically connected to metal tab for thermal and electrical conduction.
Pin 2	Power Source	Current return path for main power loop; carries full load current but not referenced for gate drive.
Pin 3	Driver Source	Kelvin sense point for gate driver feedback; decouples gate loop from power loop to suppress oscillation.
Pin 4	Gate	Control input; requires 0–18 V drive with ≤100 nA leakage; internal R_G,int = 3.0 Ω.

Key Features

Feature	Design Value
Separate driver source pin	Enables true Kelvin gate drive, reducing effective gate resistance and improving switching consistency under high di/dt.
100% avalanche tested	Guarantees single-pulse ruggedness to 926 mJ without derating-critical for traction inverter fault tolerance.
AEC-Q101 qualified	Validated for automotive under-hood use including temperature cycling, humidity, and mechanical shock per JESD47.
Low C_rss/C_iss ratio	Typ. 37 pF / 6137 pF = 0.006 - Minimizes Miller-induced dv/dt coupling and improves noise immunity.
Robust V_GS(th) stability	3.5–5.6 V over −55 °C to 175 °C - Ensures reliable turn-on margin across full automotive ambient range.

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
Wolfspeed C3M0065070D	R_DS(on) = 6.5 mΩ (lower), Q_G = 160 nC, no driver source pin, TO247-3 package	Lacks Kelvin source; requires careful PCB layout to avoid gate ringing in >100 kHz designs	Prefer when cost sensitivity outweighs need for ultra-stable gate control in lower-power OBCs
ROHM SCT3080ALHRL	R_DS(on) = 8.0 mΩ, Q_G = 152 nC, driver source pin included, same PG-TO247-4 footprint	Slightly higher R_DS(on) but tighter V_GS(th) distribution (4.0–5.0 V); lower E_oss (52 μJ)	Preferred for space-constrained traction inverters where gate drive simplicity and layout reproducibility are critical

Compared with C3M0065070D and SCT3080ALHRL, AIMZA75R008M1HXKSA1 offers the best balance of low R_DS(on) × Q_G, integrated Kelvin source, and AEC-Q101 validation-making it optimal for production-grade automotive inverters requiring zero field returns.

FAQ

What is the maximum recommended gate drive voltage for AIMZA75R008M1HXKSA1?

The datasheet specifies a recommended turn-on voltage of 18 V and turn-off voltage of 0 V. Static gate-source voltage must stay within −2 V to +20 V, and transient spikes may reach −10 V to +25 V for ≤500 ns. Exceeding these ranges risks accelerated gate oxide degradation and threshold shift over lifetime.

Can the driver source (Pin 3) and power source (Pin 2) be shorted together?

No. The datasheet explicitly warns that exchanging or shorting Pins 2 and 3 may cause malfunction. Pin 3 provides Kelvin feedback for gate control; tying it to Pin 2 reintroduces source inductance into the gate loop, degrading switching speed and increasing risk of oscillation or false turn-on.

Is AIMZA75R008M1HXKSA1 suitable for linear-mode operation?

No. The datasheet states "Linear mode operation is not recommended" and directs users to contact Infineon sales for assessment if required. This device is optimized for switching applications only; its SOA and thermal limits do not support sustained linear (ohmic) conduction.

What is the thermal resistance from junction to case (R_th(j–c))?

R_th(j–c) is 0.29 °C/W, measured per JESD51-14. This value is verified by design and characterization-not subject to production test-but applies to standard mounting conditions with 60 Ncm screw torque and proper thermal interface material on the tab surface.
