APPLICATION NOTES
The 5KP series of high power transient voltage suppressors
were designed to be used on the output of switching power
supplies. These devices may be used to replace crowbar
circuits. Both the 5 % and 10 % voltage tolerances are
referenced to the power supply output voltage level.
They are able to withstand high levels of peak current while
allowing a circuit breaker to trip or a fuse blow before
shorting. This will enable the user to reset the breaker or
replace the fuse and continue operation. For this type
operation, it is recommended that a sufficient mounting
surface be used for dissipating the heat generated by the
Transient Voltage Suppressor during the transient or
over-voltage condition.
