Notes: (1) V(BR) measured after IT applied for 300µs IT=square wave pulse or equivalent
(2) Surge current waveform per Fig. 3 and derate per Fig. 2
(3) For bidirectional types with VWM of 10V and less, the ID limit is doubled
(4) For the bidirectional 5KP5.0CA, the maximum VBR is 7.25V
(5) All items and symbols are consistent with ANSI/IEEE C62.35
Application
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 percent 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.
Transient Voltage Suppressors are Silicon PN Junction devices designed for absorption of high voltage transients associated with power
disturbances, switching and induced lighting effects.
