P6KE6.8 thru P6KE550CA

Descriptions

The 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

the unpredictable nature of transients, and the variation of the impedance with respect to these transients, impedance

is not specified as a parametric value. However, a minimum voltage at low current conditions (BV) and a maximum

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.
