Introduction: With the explosive growth of “NewSpace” and low Earth orbit (LEO) satellite constellations, market demand for cost-effective, radiation-hardened devices in automotive-grade plastic packages has surged. As a key player in the electronic components supply chain, Shenzhen Mingjiada Electronics Co., Ltd. has announced that it is actively acquiring inventory of Infineon’s recently launched full range of radiation-hardened MOSFETs and traditional high-reliability power devices to support asset revitalization and project upgrades for global aerospace and high-end industrial customers.
Market Background: The “Plastic” Revolution in Radiation-Hardened Devices
Traditional space-grade MOSFETs typically use expensive ceramic or metal packages, resulting in high costs and long lead times. To adapt to the short cycle times, low costs, and high-volume production requirements of next-generation satellites (such as Starlink-type projects), Infineon is introducing automotive-grade (AEC-Q101) plastic packaging technology into the aerospace sector.
According to reports from Infineon and industry media outlet Semiconductor Digest, Infineon has recently significantly expanded its portfolio of radiation-tolerant power MOSFETs. These devices are optimized for low-Earth orbit missions lasting 2 to 5 years, offering a perfect balance between cost and radiation resistance.
Acquisition Focus: Infineon Radiation-Tolerant and High-Reliability MOSFETs
Leveraging nearly three decades of industry expertise, Mingjiada Electronics (hkmjd.com) is now seeking to acquire the following categories of Infineon high-reliability MOSFETs from global manufacturers, distributors, and research institutions:
1. Next-Generation Plastic-Packaged Radiation-Tolerant MOSFETs (NewSpace-Grade)
This is currently the focus of market attention and the core target of this acquisition. Unlike traditional radiation-hardened (Rad Hard) devices, these devices utilize plastic packaging and employ CoolMOS super-junction technology to achieve extremely low on-resistance and high-speed switching.
Specific models and technical specifications:
N-Channel: Covers 60V and 150V voltage ratings. For example, subsequent plastic-packaged replacement models for the relevant IRHN series, featuring a total ionizing dose (TID) resistance of 30–50 krad(Si) and a single-event event (SEE) resistance of 46 MeV·cm²/mg.
P-Channel: Infineon’s newly released 60V radiation-hardened P-channel MOSFETs. These devices are used for high-side drive or reverse-connection protection in complex bridge-drive circuits, complementing N-channel devices.
Package Features: Must be plastic-packaged and tested to AEC-Q101 standards (including additional aerospace-grade outgassing tests).
2. Sealed-Case Radiation-Hardened MOSFETs (HiRel Aerospace Grade)
For high-orbit satellites or deep-space exploration missions with service lives of up to 15 years, Mingjiada also sources traditional ceramic/metal-cased radiation-hardened devices.
Sourcing Focus: IR HiRel series utilizing proprietary radiation-hardened technologies such as R9.
Key Specifications: High total radiation dose resistance ranging from 100 kRad to 300 kRad, SEE resistance up to 90 MeV/(mg/cm²), and RDS(on) as low as 25 mΩ (typical).
Package Types: Surface-mount ceramic package (SMD-0.5) or bare die.
3. CoolSiC™ Silicon Carbide MOSFET Modules (Industrial and High-Voltage)
Although primarily designed for industrial applications, Mingjiada has recognized their potential in radiation testing and high-end power supply requirements, and has simultaneously acquired the full range of Infineon’s CoolSiC™ modules on a large scale:
62mm half-bridge modules: Specifically, 1200V and 2000V modules utilizing M1H chip technology, such as the FF1MR12KM1H and similar models.
EasyPACK™ / HybridPACK™: Power modules for energy storage, electric vehicle charging, and 800V electric drive systems.
Why Choose Mingjiada?
Mingjiada Electronics not only focuses on general industrial products but also leverages its professional technical evaluation team to specialize in resolving inventory backlog issues in high-reliability sectors, particularly for the aforementioned aerospace-grade, automotive-grade, and high-performance SiC devices.
Professional Evaluation Capabilities: We can distinguish the subtle technical differences between industrial-grade, automotive-grade (AEC-Q), and true aerospace-grade (radiation-hardened/ruggedized) devices to ensure accurate pricing.
Capital and Efficiency: As a well-capitalized spot market participant, we offer rapid payment within 1–3 business days for large-volume inventory clearance (especially discontinued and surplus/obsolete parts).
Compliant Channels: We purchase exclusively through authorized distributors, OEM factories, and legitimate traders to ensure transparent and compliant processes.
