Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The 1N5819UB1 Schottky diode is ESCC certified. It is available in a surface-mount hermetically sealed ceramic LCC-2B package with a footprint that is fully compliant with the industry standard of D5B. Its all-planar technology provides excellent performance and high reliability at junction temperatures up to 150 °C. The diode is ESCC certified. The diode is ESCC certified for use in the space programme. It is commonly used in switch-mode power supplies, high-frequency DC-DC converters, or low-voltage buck chopper drivers to perform secondary rectification, redundant OR-Ing, freewheeling diode, or reverse polarity protection.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
