Protect your device from high temperature

In the previous article, we informed you about bridge rectifiers by MDD. If your device needs to be  protected from possible high temperatures, you are in the right place. The patented thermal fuse for surface mounting protects against heat leakage of power semiconductors, such as: MOSFET, IC, IGBT, Triac, SCR, etc., that is why it should be the right solution for you. Its high reliability is mainly due to complete galvanic separation. The thermal fuse separates the rated voltage up to 60 VDC. Galvanic separation occurs inside the RTS housing. And thanks to the integrated shunt, PCB space can be saved. The mechanical activation takes place only after mounting, with this fuse, therefore there will be no damage during mounting on the line. After activating this non-resettable fuse, it will work up to 210 ° C, once this temperature is reached it will disconnect the components and thus protect all parts of the device
