Abstract

MOS Transistors and Integrated Circuits are normally shipped and handled with shorting rings or loops of bare wire which tie all the device leads together to prevent static discharges from entering the device and destroying it, This ring must be removed before use,

ELEMENT

MOS Transistors and Integrated Circuits are normally
shipped and handled with shorting rings or loops of
bare wire which tie all the device leads together to
prevent static discharges from entering the device
and destroying it, This ring must be removed before
use,

To provide temporary protection, a fuse element is
wired from the leads to be protected to the case.
The fuse element is chosen so that it can be removed
by the application of a low voltage high current
source. The clearing voltage would be too low to
harm the MOS device and the clearing current would
be higher than that of a static discharge.
