DC output

Circuit Protection of DC output

Design Notes:

Protection Application:
The DC output of the power supply will experience less severe transient surges than the AC input. For this reason, circuits where added protection is desired, TVS diodes can be used. There will typically be multiple DC circuits, including +3.3V, -5V, +5V, -12V and +12VDC.
Solution Description:
As shown at the left, a TVS diode can be used to provide additional transient protection on each DC output of the power supply. This will minimize the transient stress on the power components on the respective DC power buses.
Companion Solutions:
Does not apply.
Regulatory Issues:
Standards will vary depending on the product to be protected. Examples include: IEC 61000-4-5 UL1414 UL1449
Unique Features:
