    • 4H-SI: >1E5 Ω·cm

Packaging:
Available in multi-wafer cassettes or single-wafer containers for maximum protection.

Applications

The 2-inch SiC wafer is designed for a wide range of cutting-edge applications, including:

  • Power Electronics: High-efficiency power devices such as MOSFETs, IGBTs, and Schottky diodes.
  • RF Electronics: Suitable for high-frequency amplifiers and RF modules.
  • Optoelectronics: High-performance photodetectors and UV photodiodes.
  • Research & Development: Ideal for material characterization and prototype development in academic and industrial labs.
  • Dummy Grades: Perfect for process testing, calibration, and equipment tuning without using high-cost prime wafers.

This wafer's superior thermal stability, high breakdown voltage, and wide bandgap make it indispensable for applications demanding high efficiency, robustness, and reliability. Whether for prototyping, production, or research, this SiC wafer delivers performance you can trust.

    Note: (PO) boxes or FPO/APO military addresses can only be shipped out by standard shipping method).
    The shipping fare for the expedited shipment method may higher than the standard one you chose for, then please be aware that you may ask to pay for the balance for the pertinent shipment substitution. You are welcome to contact our customer service via “contact us” for further inquiry and requisition.

  • Shipping cost all about

    It is deeply appreciated to take your kind pardon for any misunderstanding about the shipping price due to the package is shipped from China.
    The contract we have stipulated with FedEx, DHL, UPS and EMS is already set and therefore all merchandise is sent via Air rather than Ground. While this may not be the most cost effective for all customers, in terms of delivery time, ease of shipment and reliability we have determined that this is the most effective overall.
    The shipping cost for all merchandises are displayed by adding items to your shipping bag, you can estimate shipping time and cost and acquire more shipping cost information from our site.

  • International Shipping

    International shipping costs are calculated in U.S. currency based on estimated shipment weight and destination. Shipping costs for orders placed on the website are fairly accurate, but there are times when those estimates are incorrect. If we need to adjust shipping charges for your order we will contact you to authorize those additional shipping charges.
