Mingjiada Supply Infineon IMZA65R027 650V Silicon Carbide CoolSiC™ MOSFET Discretes

As applications such as photovoltaic energy storage, electric vehicle charging, server power supplies and industrial drives place ever-increasing demands on high efficiency, high power density and high-temperature reliability, silicon carbide (SiC) MOSFETs are rapidly becoming the mainstream choice in high-voltage power supply design. Mingjiada Electronics supplies the Infineon IMZA65R027 650V CoolSiC™ MOSFET discrete device, offering customers stock enquiries, sample procurement, small-batch orders and BOM fulfilment services to help R&D and procurement teams shorten the product selection cycle.

Product Overview: 650V CoolSiC™ MOSFET, on-resistance rating of approximately 27mΩ
The IMZA65R027 is part of Infineon’s CoolSiC™ MOSFET 650V series of discrete devices; the ‘027’ in the model number corresponds to an on-resistance rating of approximately 27mΩ, making it suitable for high-voltage power supply topologies with stringent requirements for conduction losses, switching losses and power density. Based on silicon carbide (SiC) material, this device typically offers lower switching losses and more stable high-temperature characteristics under high-voltage, high-frequency and high-temperature operating conditions compared to traditional silicon-based MOSFETs. This helps to improve system efficiency, reduce thermal management demands and minimise the size of magnetic components and filtering devices.

In typical designs, the IMZA65R027 can be used in topologies such as totem-pole PFC, LLC/CLLC resonant converters, DC-DC boost and buck converters, on-board chargers (OBCs), photovoltaic inverters, energy storage converters and industrial power supplies. Its 650 V voltage rating covers common 400 V DC bus and high-voltage conversion scenarios, making it suitable for power supply solutions requiring a balance of efficiency and reliability. Specific package types, gate drive requirements, thermal resistance and dynamic parameters should be subject to Infineon’s official data sheets and actual part specifications.

Key Technical Features and Design Benefits (IMZA65R027)
1. Low-loss advantages offered by silicon carbide (SiC) material
CoolSiC™ MOSFETs feature low on-resistance and switching losses, helping to improve power conversion efficiency; they are particularly well-suited to high-frequency switching and hybrid hard-switching/soft-switching topologies. For server power supplies, telecommunications power supplies and EV charging station modules, improved efficiency translates directly into reduced thermal management costs and increased power density.
2. 650V voltage rating covers mainstream high-voltage busbar applications
The 650V rating is suitable for 400V DC buses, PFC outputs and a variety of high-voltage DC-DC scenarios, providing a wide voltage margin for photovoltaic, energy storage, UPS and industrial drive applications.
3. High-Temperature Stability and Reliability
Silicon carbide devices exhibit relatively stable on-state characteristics at high temperatures, helping to simplify thermal management design and enhance system reliability in harsh environments. For outdoor or high-load equipment such as charging points and photovoltaic inverters, device reliability is a key consideration in product selection.
4. Flexible Discrete Device Solutions
As a discrete MOSFET, the IMZA65R027 allows designers to flexibly configure layouts based on power rating, number of parallel devices, thermal management structures and drive schemes, making it suitable for a wide range of design requirements from small-to-medium power supplies to higher-power modules.

Typical Applications of the IMZA65R027
Photovoltaic inverters and micro-inverters;
Energy storage power converters (PCS) and battery energy storage systems;
Electric vehicle charging points and on-board chargers (OBC);
Server power supplies, telecommunications power supplies and UPS systems;
