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.
