Product details
Overview
FS03MR12A6MA1LB from Infineon is a HybridPACK™ Drive power module integrating dual 1200 V CoolSiC™ MOSFETs and anti-parallel body diodes in a single direct-cooled PinFin baseplate package. It delivers 400 A nominal drain current, 8.5 nH stray inductance, and operates up to 150 °C junction temperature-designed for high-efficiency traction inverters in battery electric vehicles.
For engineers reviewing the FS03MR12A6MA1LB datasheet, FS03MR12A6MA1LB pinout, FS03MR12A6MA1LB application, or FS03MR12A6MA1LB equivalent, key selection criteria include its 1200 V/400 A SiC MOSFET rating, integrated NTC thermistor (5 kΩ @ 25 °C), low RDS,on (3.7 mΩ typ. @ 25 °C), and UL 94 V0 / AQG 324-qualified automotive qualification status.
Technical Context
This module implements a half-bridge topology with two co-packaged 1200 V CoolSiC™ MOSFETs sharing a common source terminal and featuring ultra-low gate charge (QG = 1.32 µC) and reverse transfer capacitance (Crss = 0.17 nF). Its internal layout achieves <10 nH stray inductance and uses Si3N4 ceramic for isolation between terminals and heatsink.
The integrated NTC thermistor (R25 = 5 kΩ, B25/100 = 3433 K) enables real-time junction temperature monitoring, while the PressFIT contact technology eliminates soldering and supports high-reliability thermal cycling in automotive traction drives operating at 150 °C continuous junction temperature.

FAQ
What is the maximum allowable case temperature for FS03MR12A6MA1LB during continuous operation?
The module's terminal temperature (Tterminal) must not exceed 105 °C for 500 A RMS current rating. Its junction temperature (Tvj,op) is rated up to 150 °C, verified per AQG 324 with 4.5σ statistical confidence. Thermal design must ensure Rth,j-f ≤ 0.108 K/W using 50 % water / 50 % ethylene glycol coolant at 10 dm³/min flow rate.
Does FS03MR12A6MA1LB require external gate resistors for standard automotive gate drivers?
Yes-external gate resistors are required. The module has no internal gate resistor beyond the specified 0.23 Ω RG,int. Recommended values are RG,on = 5.1 Ω and RG,off = 5.1 Ω for balanced turn-on/turn-off timing and EMI control, as validated in the datasheet's energy loss and switching time measurements.
How is the integrated NTC thermistor calibrated, and what is its accuracy over temperature?
The NTC has R25 = 5 kΩ ±5 % at 25 °C and B-values of 3433 K (25/100 °C), with deviation ΔR/R ≤ ±5 % at 100 °C. Calibration follows the Steinhart-Hart equation using the provided B25/100 coefficient, enabling ±1.5 °C temperature measurement accuracy from -40 °C to 150 °C when paired with a 1 % precision bias resistor.
Can FS03MR12A6MA1LB be used in a three-phase inverter without additional external components?
No-it contains one half-bridge (two switches). A full three-phase inverter requires three identical modules (six total switches) or one module per phase leg. Gate drive isolation, DC-link capacitors, current sensors, and NTC signal conditioning remain external, as confirmed by the circuit diagram in section 6 of the datasheet.
