Power supply equipment design scheme: DC output TVS Diode

   Circuit protection of DC output current

Protection application:

The transient surge of DC output terminal of power supply equipment is less than that of AC input terminal. Therefore, the circuit that needs to be protected can use transient suppression diode. There are usually multiple DC circuits, including + 3.3V, - 5V, + 5V, - 12V and + 12VDC circuits.

Solution Description:

As shown in the figure above, the transient suppression diode is used to provide additional transient protection for each DC output of the power supply. This will minimize the transient pressure on each DC power bus power supply device.

Solution: TVs transient suppression diode
