Product details
Overview
FS03MR12A6MA1BBPSA1 from Infineon is a HybridPACK™ Drive module integrating dual 1200 V, 400 A CoolSiC™ MOSFET half-bridge switches with integrated NTC thermistor and press-fit terminals, designed for high-power traction inverters in electric drivetrains. It delivers 2.75 mΩ RDS(on) at 25 °C, <8.5 nH stray inductance, and 150 °C maximum junction temperature operation under direct liquid cooling.
For engineers reviewing the FS03MR12A6MA1BBPSA1 datasheet, FS03MR12A6MA1BBPSA1 pinout, FS03MR12A6MA1BBPSA1 application, or FS03MR12A6MA1BBPSA1 equivalent, key selection criteria include SiC-based switching loss reduction, 4.2 kV DC insulation rating, 720 g mass with PinFin baseplate, and compatibility with AQG324 automotive qualification requirements.
Technical Context
This module implements a dual-channel, isolated half-bridge topology using silicon carbide MOSFETs with co-packaged body diodes and an integrated NTC sensor. Its low-inductance layout (<8.5 nH) and 0.1 K/W junction-to-fluid thermal resistance enable high-frequency, high-efficiency operation up to 150 °C junction temperature under 50/50 water-glycol coolant flow.
The press-fit contact technology eliminates solder reflow, while the Si3N4 ceramic baseplate and 9.0 mm creepage distances meet IEC 61140 Class 1 basic insulation requirements for automotive traction systems. Gate drive interface uses standard ±5 V/15 V logic-level signals with internal 0.23 Ω gate resistors.

FAQ
What is the maximum allowable coolant flow rate and pressure for FS03MR12A6MA1BBPSA1?
The module supports up to 10 dm³/min coolant flow at 60 °C with a maximum pressure of 2.5 bar below 40 °C baseplate temperature and 2.0 bar above 40 °C. Exceeding these limits risks mechanical deformation of the PinFin structure or seal failure, as validated per AN-HPDPERF-ASSEMBLY guidelines.
Does FS03MR12A6MA1BBPSA1 require external gate resistors?
No-each gate channel includes an internal 0.23 Ω resistor, optimized for use with standard ±5 V/15 V isolated gate drivers. External resistors are unnecessary unless fine-tuning of dv/dt or switching speed is required for specific EMI or voltage overshoot constraints.
How is the NTC thermistor calibrated and what tolerance applies?
The integrated NTC has a nominal 5 kΩ resistance at 25 °C with ±5% deviation at 100 °C (ΔR/R), and B-values of 3375 K (25/50 °C), 3411 K (25/80 °C), and 3433 K (25/100 °C). Calibration follows IEC 60751 Class B, enabling ±1.5 °C accuracy across the full –40 to 150 °C operating range.
Can FS03MR12A6MA1BBPSA1 be used in non-automotive industrial motor drives?
Yes-it is qualified to AQG324 for automotive but also meets industrial standards including UL 94 V0, 4.2 kV DC isolation, and 125 °C storage temperature. Its 150 °C operational limit and low-inductance design make it suitable for high-performance servo drives and renewable energy converters where efficiency and thermal headroom are critical.
