Circuit Protection of DC input

Solutions

Design Notes:

Protection Application:

For satellite radios that include an external AC adapter, a DC voltage (typically in the range of 5VDC to 6VDC) will be supplied. The electrical threats include ESD, low-level lightning surges, and overcurrent conditions (short circuit or overload).

Solution Description:

As shown at the left, a fuse or PTC can be used for short circuit and overload current conditions. For surge and ESD protection, an MLV can be used.

Companion Solutions:

Does not apply.

Regulatory Issues:

If ESD is a concern, the IEC 61000-4-2 can be consulted to find information on the test method and transient waveform that should be used.
