HL Haolin Elec SR840 T B Schottky Barrier Diode for High Frequency Inverters and Polarity Protection
Product Overview
This series of Schottky Barrier Diodes, manufactured by SHENZHEN HAOLIN ELECTRONICS TECHNOLOGY CO., LTD, offers high-efficiency rectification for various electronic applications. Designed with a plastic package featuring UL Flammability Classification 94V-0 and a metal silicon junction for majority carrier conduction, these diodes provide low power loss and high current capability. They are ideal for low voltage, high frequency inverters, free wheeling, and polarity protection applications, benefiting from a guard ring for overvoltage protection and high surge capability. The diodes are guaranteed for high-temperature soldering.
