P6KE6.8A Series
600 Watt Peak Power
Surmetict-40 Transient
Voltage Suppressors
Unidirectional*
The P6KE6.8A series is designed to protect voltage sensitive
components from high voltage, high energy transients. They have
excellent clamping capability, high surge capability and fast response
time. These devices are ON Semiconductor’s exclusive,
cost-effective, highly reliable Surmeticꢀ axial leaded package and is
ideally-suited for use in communication systems, numerical controls,
process controls, medical equipment, business machines, power
supplies and many other industrial/consumer applications.
