Mingjiada Supply/Recycle Infineon AIMZA75R040M2H 750V Automotive Silicon Carbide CoolSiC™MOSFETs

As the demands for energy efficiency and power density continue to rise in new energy vehicles, charging points and high-end industrial power supplies, silicon carbide (SiC) power devices are gradually replacing traditional silicon-based devices. The AIMZA75R040M2H, a 750V automotive-grade CoolSiC™ MOSFET, has become the preferred choice for numerous demanding power electronics designs thanks to its outstanding switching performance, high-temperature stability and reliability.

Shenzhen Mingjiada Electronics Co., Ltd. — a long-standing supplier and recycler of automotive-grade silicon carbide (SiC) power devices such as the AIMZA75R040M2H — offers genuine, original products, stock availability and surplus stock recycling services, helping new energy vehicle and industrial power supply companies to reduce costs and improve efficiency.

AIMZA75R040M2H Product Overview
The AIMZA75R040M2H is a 750V automotive-grade silicon carbide (SiC) MOSFET developed by Infineon based on second-generation CoolSiC™ trench technology. It is housed in a PG-TO247-4 (4-pin asymmetric lead) package, with a typical on-resistance of 40 mΩ and a continuous drain current of 40 A (at 25°C). The device is AEC-Q101 automotive-grade certified, operates within a junction temperature range of –55°C to 175°C, and offers high reliability, low switching losses and excellent resistance to parasitic conduction. It is specifically designed for automotive high-voltage systems and high-efficiency power supplies.
Part Number: AIMZA75R040M2H
Drain-source voltage (VDS): 750 V, suitable for 400 V to 800 V battery systems
On-resistance: Rds(on) = 40 mΩ (Tj = 25 °C)
Continuous drain current (ID): 40 A
On-resistance (RDS(on)): Typical value 40 mΩ (at VGS = 18 V), reducing on-resistance losses
Package: PG-TO247-4, with Kelvin source pin, optimising the drive circuit and minimising switching oscillations
Operating junction temperature (Tj): Up to 175 °C, meeting stringent thermal management requirements.

Key Product Benefits (AIMZA75R040M2H)
Second-generation CoolSiC™ trench technology: Compared to planar structures, the trench design reduces on-resistance and switching losses whilst enhancing power density.
PG-TO247-4 four-pin package: A dedicated drive source pin reduces package parasitic inductance, improves high-speed switching performance, and suppresses ringing and EMI.
High dv/dt robustness (up to 200 V/ns): Suitable for both hard-switching and soft-switching topologies, making it ideal for high-frequency applications.
Excellent RDS(on) × Qoss and RDS(on) × Qg products: Delivers industry-leading efficiency performance in the 750 V class.
High gate threshold voltage (VGS(th) typically 5.6 V): Strong immunity to interference, reducing the risk of parasitic conduction.

Typical Applications for the AIMZA75R040M2H
New Energy Vehicles (EV/HEV): On-board chargers (OBC), high-voltage DC-DC converters, auxiliary inverters, battery protection/disconnect switches.
Charging Infrastructure: DC fast-charging modules, AC charging station power stages.
Industry and Energy: Photovoltaic inverters, Energy Storage Systems (ESS), telecommunications and server SMPS, solid-state relays, UPS.
High-Voltage Power Distribution and Circuit Breakers: Smart circuit breakers, high-voltage solid-state switches.
