APPLICATION NOTES

• This P6KE TVS series is a low cost commercial product for

use in applications where large voltage transients can

permanently damage voltage-sensitive components.

• The P6KE series device types are designed in a small

package size where power and space is a consideration.

They are characterized by their high surge capability,

Because of the unpredictable nature of transients, and the

variation of the impedance with respect to these

transients, impedance, per se, is not specified as a

parametric value. However, a minimum voltage at low

current conditions (BV) and a maximum clamping voltage

Voltage) may be responsible for 50 % to 70 % of the

observed voltage differential when subjected to high

current pulses for several duty cycles, thus making a

maximum impedance specification insignificant.

• In case of a severe current overload or abnormal transient

beyond the maximum ratings, the Transient Voltage

Suppressor will initially fail ‘short’ thus tripping the

system’s circuit breaker or fuse while protecting the entire

circuit. Curves depicting clamping voltage vs. various

current pulses are available from the factory. Extended

power curves vs. pulse time are also available.
