A switching converter is an electronic device that can convert electrical energy from one form to another. It is usually used in power supplies, chargers, adapters and other devices to convert AC to DC, or DC to AC. Switching converters have the advantages of high efficiency, compactness, and lightness, and are widely used in various electronic devices. Different types of switching converters have different characteristics and applications, such as buck converters, boost converters, flyback converters, forward converters, etc. .

In order to avoid surge voltages caused by lightning, line faults, etc. from damaging the switching power supply or interfering with subsequent electronic equipment, the surge voltage needs to be controlled within a certain range.

Socay Electronics has launched the ceramic gas discharge tube SC3E5-150LSMD, which is widely used to protect switching converters.

SC3E5-150LSMD main parameters:

DC breakdown voltage: 150V
