Import Diode Rectifier M7 — Buy in Bulk from Supplier in China

The M7 diode rectifier is a surface-mount device designed for general-purpose rectification in electronic circuits, featuring a plastic encapsulated package with a maximum reverse voltage of 1000V and a forward current rating of 1A. It complies with Underwriters Laboratories Flammability Rating 94V-0, indicating its flame-resistant housing material. The device is optimized for automated assembly and is commonly used in low-to-medium power applications where space efficiency and thermal stability are critical.

The diode is constructed using a silicon PN junction with a standard plastic epoxy body, typical of industry-standard SMD rectifiers in the M7 form factor. Its lead-free construction meets RoHS guidelines, and the package dimensions follow the standard DO-214AC (SMA) footprint. While the listing does not specify forward voltage drop or reverse leakage current, typical values for this class of diode range from 0.85V to 1.1V at rated current and under 5µA at room temperature, respectively.

This component is sourced by manufacturers in telecommunications, automotive control modules, and consumer electronics for power supply circuits, AC-DC conversion, and reverse polarity protection. Buyers typically order in reels of 1000 or 3000 units for automated PCB assembly. Trade terms include FOB and CIF shipping from Guangdong ports, with packaging in anti-static tape and reel or bulk tray formats. Minimum order quantities are not stated and should be confirmed directly with the supplier.

Kingtronics International Company is a supplier based in Changping, Dongguan, Guangdong, China, with an imported tier classification and harbor trust verification. The company specializes in discrete semiconductor components, including rectifiers, Zener diodes, and transient voltage suppressors. This listing does not indicate years in operation, production capacity, or client names, nor does it list certifications beyond the UL 94V-0 rating referenced for the M7 package.

The supplier's profile confirms physical presence in a manufacturing region known for electronics component production but provides no public details on quality systems, testing equipment, or R&D capabilities. Responses to buyer inquiries are not tracked, indicating no active customer service infrastructure on the platform. Buyers should request documentation directly to confirm compliance with industry standards beyond the stated flammability rating.
