Dimensions of mold length and diameter do not include mold flash and gate burr, mold flash shall not exceed 0.015 inch per side. These
dimensions are measured at the outermost extreme of the plastic body
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.
• In some instances, the thermal effect (see Vc Clamping
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.
• 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,
extremely fast response time, and low impedance, (Ron).
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
(Vc) at a maximum peak pulse current is specified.
• 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.
