P6KE6.8A Series
600 Watt Peak Power
Surmetict-40 Zener Transient
Voltage Suppressors
Unidirectional*
http://onsemi.com
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, low zener
impedance and fast response time. These devices are
ON Semiconductor’s exclusive, cost-effective, highly reliable
Surmetict 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.
