Mingjiada Electronics Supplies Infineon Automotive-Grade MOSFETs: AEC-Q101 Certified, OptiMOS™ 5/6/7 and CoolMOS™ S7A in Stock, Covering OBC, Traction Inverters, and 800V High-Voltage Platforms

As the electrical architecture of new energy vehicles accelerates its evolution from 400V to 800V, on-board chargers (OBCs), DC-DC converters, battery management systems (BMS), and traction inverters are placing increasingly stringent demands on the voltage rating, conduction loss, and high-temperature reliability of automotive-grade power MOSFETs. Shenzhen Mingjiada Electronics Co., Ltd., an authorized independent distributor of electronic components established in 1996, leverages its dual warehouse network in Shenzhen and Hong Kong to provide a long-term supply of Infineon automotive-grade MOSFETs from stock, covering the OptiMOS™ 5/6/7, CoolMOS™ S7A super-junction series, and CoolSiC™ silicon carbide automotive-grade products. We provide AEC-Q101-certified genuine devices and BOM fulfillment support to customers in the automotive electronics and new energy power conversion sectors.

I. What Types of Infineon Automotive-Grade MOSFET Products Does Mingjiada Supply?

Mingjiada Electronics’ supply portfolio for Infineon automotive-grade power devices is not based on sporadic stocking of individual models, but rather on a tiered matrix organized by technical platforms and application voltage ranges.

1. OptiMOS™ Series: The Main Platform for Mid-to-Low-Voltage Automotive-Grade MOSFETs

OptiMOS™ is Infineon’s flagship technology platform in the field of low- to medium-voltage automotive-grade MOSFETs. Mingjiada maintains a stock of models covering 5th, 6th, and 7th generation products, with voltage ranges concentrated between 30V and 300V. These are primarily targeted at applications such as body control, electric power steering (EPS), battery isolator switches, 48V mild hybrid systems, and auxiliary power supplies for traction inverters. Specific available models include:

OptiMOS™ 7 Automotive Grade: IAUCN04S7L038D, IAUCN04S7L018D, IAUAN04S7N012, IAUCN10S7N025T, IAUCN08S7N036T, IAUTN08S7N007, IAUTN10S7N009, etc.;

OptiMOS™ 6 Automotive Grade: IAUCN04S6N007T, IAUCN04S6N013T, IAUTN15S6N025T, IAUTN15S6N038T, etc.;

OptiMOS™ 5 Automotive Grade: IAUCN10S5L110T, IAUT300N08S5N012, IAUT260N10S5N019, IAUC100N10S5L040, IAUS200N08S5N023, etc.

OptiMOS™ 7 achieves RDS(on) reductions of up to 25% and 40% compared to the previous generation at the 40V and 80V/100V nodes, respectively. Combined with packages such as TOLL, SSO8, and S3O8, it is suitable for high-current automotive designs with stringent requirements for power density and parallel consistency.

2. CoolMOS™ S7A Automotive-Grade Super-Junction MOSFETs: A Cost-Effective Choice for High-Voltage Automotive Applications

For high-voltage automotive power distribution, the PFC stage of on-board chargers (OBCs), and high-voltage solid-state switches, Mingjiada supplies Infineon’s CoolMOS™ S7A series of automotive-grade N-channel high-voltage MOSFETs. Represented by the IPDQ60R series, these devices feature a 600V rating, a maximum RDS(on) of 17 mΩ, and a PG-HDSOP-22 (Q-DPAK) bottom-cooled package. Featuring a Kelvin-source design and AEC-Q101 certification, these devices operate within a temperature range of -40°C to 150°C and are suitable for applications such as PFC in on-board chargers, high-voltage solid-state relays, and battery protection modules.

3. CoolSiC™ Automotive-Grade Silicon Carbide MOSFETs: Leading Options for the 800V High-Voltage Platform

To meet the demands of 800V high-voltage architectures and higher switching frequencies, Mingjiada simultaneously supplies Infineon’s CoolSiC™ automotive-grade MOSFETs, with voltage ratings covering 400V, 650V, 750V, 1200V, and higher. CoolSiC™ devices can significantly reduce switching losses in on-board chargers (OBCs) and high-voltage DC-DC converters, supporting improved system efficiency and optimized power density, making them a key component option for next-generation high-voltage power conversion in electric vehicles.

II. Key Application Scenarios for These Automotive-Grade MOSFETs in Automotive Electronics

The Infineon automotive-grade MOSFETs supplied by Mingjiada address several critical nodes in the automotive powertrain where reliability requirements are most stringent:

On-Board Charger (OBC): The CoolMOS™ S7A and CoolSiC™ series cover the 600V PFC stage and the 750V/1200V high-voltage DC-DC stage, respectively, and are suitable for 11kW/22kW OBC designs.

DC-DC Converters and BMS: The low- to medium-voltage models of the OptiMOS™ 5/6/7 series provide low on-resistance solutions for low-voltage DC-DC converters, battery isolation switches, and main circuit protection in the 40V to 150V range.

Traction Inverters and Electric Drive Auxiliary Power Supplies: The OptiMOS™ 6 150V series, featuring RDS(on) values in the 2.5 mΩ range and TOLL/TOLG/TOLT packages, supports the use of multiple devices in parallel in high-power electric drive and auxiliary power applications; CoolSiC™ is designed to meet the high-frequency, high-efficiency requirements of 800V main drive inverters.

Body and Chassis Electronics: AEC-Q101-certified low- to medium-voltage automotive-grade MOSFETs are also widely used in electric power steering, braking systems, LED lighting, and load switches within domain controllers.

III. Why AEC-Q101 and Supply Chain Qualifications Are Critical for Procuring Automotive-Grade MOSFETs

The core distinction between automotive-grade MOSFETs and industrial-grade devices lies not in the voltage and current specifications listed in the datasheets, but in the reliability verification system and batch consistency. Infineon’s automotive-grade MOSFETs are generally AEC-Q101 certified, with operating junction temperatures up to 175°C. Some series (such as the OptiMOS™ 6 150V) feature a thermal resistance as low as 0.4 K/W and support the PPAP (Production Part Approval Process). For safety-critical applications such as on-board chargers (OBCs) and inverters, whether the devices come from traceable, legitimate channels and whether the batches maintain original manufacturer consistency directly impact the validation cycle and mass production risks of the entire vehicle project.

Mingjiada Electronics holds ISO 9001 Quality Management System certification and ISO 14001 Environmental Management certification. We guarantee that all Infineon automotive-grade MOSFETs we supply are genuine factory products with full batch traceability, and we support a phased procurement model ranging from sample requests and small-batch trial production to mass production BOM order fulfillment. For teams currently developing 800V platforms or next-generation OBC designs, this means they can validate Infineon’s automotive-grade devices early in the selection process with a low barrier to entry, then gradually transition to mass production supply.
