Mingjiada has the advantage of selling the onsemi series of photodetectors (SPAD, SiPM)

 From nanosecond-level photon capture by lidar to the detection of low-light molecules in medical images, single-photon photodetectors (SPAD/SiPM) are becoming the "ultimate eyes" of high-precision perception. onsemi, with its technical barriers of single-photon sensitivity, automotive-grade reliability and quantum efficiency, holds a core position in the global LiDAR, medical imaging and industrial inspection fields. As a well-known distributor of electronic components, Mingjiada Electronics provides "from laboratory to mass production" photonic sensing solutions for new energy vehicle manufacturers, medical equipment manufacturers and industrial automation enterprises through direct supply channels from original factories and a million-level inventory reserve.

I. Technological High Ground: The Three Irreplaceability of SPAD/SiPM

1. Single-photon sensitivity: "Photon Hunter" in the Dark

onsemi's SPAD/SiPM features industry-leading photon detection efficiency (PDE) :

The SiPM series: For instance, ARRAYRDM-0112A20-QFN achieves a PDE of 16% at a wavelength of 905nm, making it the core of solid-state LiDAR long-range detection.

SPAD array: Wide field of view (FoV) design supports short/medium/long-range LiDAR applications and maintains stable depth-of-field imaging even in strong light environments.

2. Automotive-grade reliability: The "Survival Rule" in Extreme environments

AEC-Q102 certification: Resistant to a wide temperature range of -40 ° C to 125 ° C and 50G mechanical shock (such as R series SiPM), suitable for the vibration environment of the engine compartment.

Anti-ambient light interference: Integrated crosstalk suppression technology ensures that the LiDAR ranging error is ≤3cm in intense sunlight or thick fog.

3. Manufacturing process Barriers: The "Balancing Technique" between Cost and Performance

RDM patented process: Single-chip integrated 1x12-pixel array (pixel size 0.47mm×1.12mm), with a 40% increase in yield compared to the traditional APD solution;

QFN package enhancement: 10mm×5.2mm compact size supports direct mounting, reducing the complexity of optical calibration.

Ii. Mingjiada Supply Matrix: Focusing on Three Major "Photon Fundamental Frequencies"

1. LiDAR dedicated Detector: The "Visual hub" of Autonomous Driving

Long-range LiDAR: The SiPM series (such as the RD series) empowers RoboSense RS-LiDAR-M1 (CES Innovation Award product), with a detection range of > 200m and an accuracy of ±2cm;

Solid-state flash LiDAR: The SPAD array supports a non-scanning architecture, replacing mechanical rotation solutions and reducing costs by 60%.

2. Medical Imaging and Scientific Research Exploration: The "Photon Microscope" in Life Sciences

PET molecular imaging: The high gain characteristic of SiPM enhances the efficiency of gamma photon capture, and the imaging resolution exceeds 0.5mm.

Quantum communication: The single-photon timing accuracy of SPAD is less than 100ps, providing a hardware foundation for quantum key distribution.

3. Industrial Safety and National Defense Perception: The "Decoder" of Invisible Light

Short-wave infrared (SWIR) detection: Supports onsemi's new CQD technology (acquired SWIR Vision Systems), detects defects through smoke/plastic, with a wavelength coverage of 2100nm;

Unmanned aerial vehicle (UAV) obstacle avoidance system: The SPAD array achieves millimeter-level accuracy ToF ranging and can withstand strong electromagnetic interference.

Iii. The three major supply advantages of Mingjiada: Solving industry pain points

1. Original factory genuine product traceability system

All SPAD/ SIPMs are provided with onsemi batch codes and vacuum packaging, supporting X-ray scanning and dynamic oven testing (-55℃ to 125℃) for verification.

2. Global dual-warehouse million-level spot goods

The dual-hub layout of Shenzhen Central Warehouse and Hong Kong constant temperature warehouse keeps over 50 onsemi detector models in stock, including rare automotive-grade SIPMs (such as the ARRAYRDM series).

Urgent orders are responded to within 24 hours: domestic delivery within 48 hours, and door-to-door service to Europe, America and Southeast Asia within 72 hours (DDP terms + anti-static cold chain logistics).

3. Flexible procurement strategies

R&d support: Minimum order of 1 piece, split supply, and free evaluation kits (such as SPAD array EVK) are included.

Mass production support: The price for orders of tens of thousands of pieces is 12% lower than the market price, and VMI consignment is supported to reduce the risk of inventory preparation.

Mingjiada Electronics, with its original factory resource penetration power and tens of millions of supply chain resilience technology value-added services, transforms the "physical limit" of photons into the "market barrier" of customers' products - enabling every beam of invisible light to be precisely captured and rewriting the precision scale with every detection.
